Oatmeal Cookies — Thick, Chewy, and Better the Next Day

Oatmeal cookies are thick, chewy drop cookies made with rolled oats, brown sugar, and butter, baked at moderate heat for 11 to 12 minutes until the edges are set and the centre stays soft. They use a brief dough-chilling step that prevents spreading and keeps the texture dense rather than flat. Total prep is under 15 minutes. Best for anyone who wants a bakery-style chewy cookie that holds its texture for up to 5 days.

This oatmeal cookies recipe gives you thick, chewy cookies with golden edges, a soft centre, and visible oat texture in every bite. One bowl, no mixer needed, 15 minutes of prep. The most common problem with homemade oatmeal cookies is flat, crispy spread — and this recipe addresses that with brown butter and a 30-minute chill that keeps every ball thick through the entire bake. I tested this recipe 4 times with different butter and sugar ratios before publishing — the version here is the one that gave me consistent thickness and a soft centre every single time.

Why This Recipe Works

Most oatmeal cookie recipes produce flat, dry discs that turn rock-hard by day two. This one is engineered for thickness and a consistently soft chew — and these are the exact reasons it works:

• Brown butter, not melted butter. — Browning the butter removes water and concentrates the milk solids into a nutty, caramel-like flavour. The result is a noticeably deeper flavour than standard melted-butter recipes — without any extra ingredients.
• More brown sugar than white. — The molasses in dark brown sugar is hygroscopic — it attracts and holds moisture in the crumb. Cookies made with all-white sugar dry out within 24 hours. These stay soft for best quality for up to 5 days.
• 30-minute dough chill. — Chilling firms the butter back up after browning, which means the dough holds its shape instead of spreading flat in the oven. This is the single biggest factor in getting a thick cookie.
• Rolled oats, not quick oats. — Rolled oats hold their structure through baking and give every bite a visible chew. Quick oats dissolve into the dough and produce a uniform, soft drop cookie rather than the classic oatmeal texture.
• One bowl, no mixer. — Every step is done with a whisk and spatula. No equipment to set up, no risk of overmixing with a stand mixer.
• Make ahead, bake to order. — The dough keeps refrigerated for up to 3 days and frozen as balls for up to 3 months — you can bake a single tray whenever you need it.

If you are building a baking repertoire, classic cookie recipes are a strong place to start once you have this one down.

Ingredients for Oatmeal Cookies

Every ingredient here has a specific job. Here is what each one does — and what to use if you need to make a substitution.

The Cookie Base

Ingredient	Amount	What It Does	Best Substitute + Impact
Unsalted butter	225g	Browned to remove water and develop deep nutty flavour; provides fat for spread control	Salted butter — omit the added salt; vegan butter block — works at 1:1, skip browning step
Dark brown sugar	200g, packed	Molasses content keeps moisture in the crumb for days after baking	Light brown sugar — slightly less depth; coconut sugar — similar result at 1:1
White granulated sugar	100g	Promotes crispy edges and helps the cookies spread to the right diameter	Omit for a softer, thicker cookie — reduce bake time by 1 minute
Large eggs	2, room temperature	Structure and moisture; the extra yolk from 2 whole eggs creates a richer, chewier crumb	Flax egg (1 tbsp ground flax + 3 tbsp water per egg) — slightly denser result
Pure vanilla extract	2 tsp	Rounds and deepens the brown butter and brown sugar flavour notes	Vanilla bean paste at 1:1; imitation vanilla at 1.5x quantity
Plain flour	190g	Structure — keeps the cookie thick and slice-clean rather than crumbly	GF plain flour blend at 1:1 + ½ tsp xanthan gum — slightly more crumbly
Baking soda	1 tsp	Lift and spread — reacts with the brown sugar to give slight rise	Baking powder at 3 tsp — less browning, slightly puffier and cakier texture
Ground cinnamon	1 tsp	The defining warm spice note in a classic oatmeal cookie	Mixed spice — similar warmth; omit for a plain oat-forward flavour
Fine sea salt	½ tsp	Balances the sweetness and makes every other flavour more pronounced	Table salt at ¼ tsp — smaller grain packs more saltiness per measure

The Oats and Mix-Ins

Ingredient	Amount	What It Does	Best Substitute + Impact
Rolled oats (old-fashioned)	270g	The defining texture — whole flakes hold structure through baking and give each bite a visible chew	Quick oats — smoother, softer cookie, less oat texture; steel-cut — too coarse, not recommended
Mix-ins (chocolate chips, raisins, or walnuts)	150g	Flavour variation and texture contrast	Any combination of dried fruit, nuts, or chocolate — keep total weight at 150g

Key Ingredient Notes

Butter temperature after browning: After browning, the butter must cool to room temperature before you add the sugars — not warm, not hot. Warm butter mixed with sugar begins to melt the sugar crystals prematurely, which removes the structure that keeps cookies thick. Wait at least 15 minutes, or place the bowl in the refrigerator for 5 minutes.

Flour measurement: Spoon flour into your measuring cup and level off with a straight edge — do not scoop directly from the bag. Scooping packs the cup and adds up to 25% more flour than the recipe calls for — that extra flour produces a stiff, dry cookie that bakes hard rather than chewy.

Baking soda freshness: Old baking soda loses its lift within 6 months of opening. Drop ½ teaspoon into hot water — if it bubbles vigorously, it is active. No bubbles means it is spent and your cookies will spread flat.

Equipment You Need

• Light-coloured saucepan — essential for browning butter; a dark pan hides the colour change and makes it easy to burn the solids.
• Large mixing bowl — you need room to fold in 270g of oats without overflow.
• 2-tablespoon cookie scoop — consistent sizing means consistent baking times across the whole tray.
• Two flat baking trays — lined with parchment paper or silicone mats; avoid dark non-stick pans, which absorb too much heat and overbrown the bottoms.
• Wire cooling rack — moves cookies off the hot tray after 5 minutes to stop carry-over baking.

The Oat Type Guide

The type of oat you use is the single biggest factor in the final texture of your oatmeal cookies. Here is what each type produces:

Oat Type	What It Looks and Feels Like	Use for This Recipe?
Rolled oats (old-fashioned)	Flat, wide flakes; hold their shape through baking; visible in every bite	✅ Best — the classic oatmeal cookie texture
Quick oats (1-minute oats)	Finely cut, thin flakes; absorb more liquid; disappear into the dough	⚠️ Works — smoother texture, less chew, slightly cakier
Instant oats (pre-cooked)	Powdery; almost no texture after baking	❌ Not recommended — produces a uniform soft cookie, no oat character
Steel-cut oats	Coarse, hard groats; do not soften in 12 minutes of baking	❌ Not recommended — gritty, hard texture in the finished cookie
Jumbo rolled oats	Extra-large flakes; dramatic texture; very visible in the baked cookie	✅ Works — slightly longer hydration time; chewy, rustic result

Workaround if you only have quick oats: Use 240g quick oats instead of 270g rolled oats (quick oats absorb more liquid). The cookies will be softer and more uniform — chill the dough for 45 minutes instead of 30 to compensate for the extra absorption.

What properly hydrated oats look like after chilling: After 30 minutes in the refrigerator, the oats should look slightly darker and feel less dry — they will have absorbed some moisture from the dough. This is correct. It is what gives you a tender, soft interior once baked.

How to Make Oatmeal Cookies — Step by Step

Follow these steps in order. The one rule that matters most: do not skip the 30-minute chill — this is what separates thick cookies from flat ones.

Step 1 — Brown the Butter

Place 225g of butter in a light-coloured saucepan over medium heat. Swirl the pan every 30 seconds — do not stir constantly, as that slows the browning. After 5 to 6 minutes you will hear the sizzling quieten as the water evaporates, and the butter will shift from yellow to golden to amber with small brown flecks on the base of the pan. The smell shifts from milky to nutty and toasty.

⚠️ Pull it at amber, not dark brown. The solids continue cooking in the hot pan after you remove it from the heat. Pour immediately into your mixing bowl — do not leave it in the pan. Dark brown solids mean burnt butter and a bitter cookie.

What to look for: Golden-amber colour, a nutty smell like toasted hazelnuts, and visible brown specks on the base of the bowl when you pour it out.

Step 2 — Mix the Sugars Into the Brown Butter

Let the brown butter cool in the bowl for 15 minutes — it should be warm but not hot to the touch. Add 200g dark brown sugar and 100g white granulated sugar. Whisk until fully combined and smooth — about 1 minute. The mixture will look like a thick, dark paste at this stage.

What to look for: A uniform dark caramel-coloured paste with no visible unmixed sugar around the edges of the bowl.

Step 3 — Add the Eggs and Vanilla

Add both eggs and 2 teaspoons of vanilla extract to the butter-sugar mixture. Whisk vigorously for a full 60 seconds — set a timer. This step builds structure: the extended whisking incorporates air and slightly thickens the mixture, which helps the cookies hold their height during baking. A quick stir is not enough.

⚠️ Whisk for the full 60 seconds. Under-whisked eggs produce a flat, dense cookie. The mixture should look glossy and slightly thickened — almost like a ribbon when you lift the whisk.

What to look for: A glossy, slightly thickened mixture that falls in a thick ribbon from the whisk.

Once you are comfortable with this method, brown butter baking techniques are worth exploring — the same principle applies across brownies, blondies, and shortbread.

Step 4 — Fold in the Dry Ingredients

Sift the plain flour, baking soda, cinnamon, and salt directly into the bowl. Switch to a rubber spatula and fold from the base of the bowl up and over — do not use the whisk at this point. Stop folding the moment you see no more dry flour streaks. The dough will be thick and slightly sticky.

Overmixing at this stage develops the gluten in the flour and produces a tough, dense cookie that spreads less but bakes hard rather than chewy. Ten extra folds is genuinely all it takes to change the texture.

What to look for: A uniform, thick dough with no visible flour pockets and no dry crumbly sections.

Step 5 — Add the Oats and Mix-Ins

Add the 270g of rolled oats and your 150g of mix-ins (chocolate chips, raisins, or walnuts). Fold in with the spatula using large, deliberate strokes. The dough will be very thick at this point — work from the bottom of the bowl and use some pressure to distribute the oats evenly.

What to look for: Oats and mix-ins distributed evenly throughout the dough, with no large unmixed pocket at the bottom of the bowl.

Step 6 — Chill the Dough

Cover the bowl tightly with cling film and refrigerate for a minimum of 30 minutes. The chilling step firms the butter back up after browning — this is what stops the dough from spreading flat in the oven. The dough can stay refrigerated for up to 3 days at this stage.

What to look for: After 30 minutes, the dough should feel firm enough to scoop cleanly — it should hold its ball shape without immediately flattening when you roll it.

Step 7 — Scoop, Space, and Bake

Preheat your oven to 175°C (350°F / Gas Mark 4). Line two flat baking trays with parchment paper. Scoop 2-tablespoon balls (about 45g each) onto the trays, spacing them at least 5cm apart — the cookies will spread slightly as they bake. Bake on the middle rack for 11 to 12 minutes.

Pull the tray when the edges look set and golden but the centres still appear slightly underdone and glossy. Leave on the hot tray for 5 minutes — they will finish cooking from the residual heat. Transfer to a wire rack to cool completely.

What to look for: Set, golden edges; a centre that looks slightly underset and pale — this is correct. After 5 minutes on the tray, press the centre gently — it should feel firm but give slightly.

The Science Behind a Perfect Oatmeal Cookie

A great oatmeal cookie result is not luck — it is four ingredients doing specific, predictable jobs at specific temperatures.

Why Brown Butter Changes the Flavour

Butter → heated past melting point → water evaporates and milk solids toast via the Maillard reaction → produces hundreds of new flavour compounds including diacetyl and pyrazines, which taste like toasted nuts and caramel. You can observe this directly: a cookie made with regular melted butter tastes flat and one-dimensional next to one made with brown butter, using identical amounts of every other ingredient.

Why Brown Sugar Over White

Dark brown sugar → contains 6 to 10% molasses → molasses is hygroscopic (it draws and holds moisture from the surrounding environment) → the crumb stays soft at room temperature for days longer than a white-sugar cookie. A cookie made with all white sugar dries out noticeably by day two. The brown sugar also contributes an acidic pH that reacts with the baking soda, giving you a slightly chewier, denser crumb rather than a puffy, cakey one.

Why Chilling Prevents Flat Cookies

Brown butter → liquefied during the browning process → needs to re-solidify to trap air and resist spreading in the oven. An unchilled dough ball hits the hot oven surface while the fat is still semi-liquid — it spreads immediately before the flour proteins set, giving you a flat disc. A chilled ball holds its shape for the first 4 to 5 minutes of baking — exactly the window the edges need to set before the centre softens. The single rule: if your dough has been in a warm kitchen for more than 20 minutes after chilling, chill it again for 10 minutes before baking.

Tips for the Best Result

These are the details that separate a good oatmeal cookie from one people ask you to make again.

• Use a kitchen scale, not cups. — Flour in particular is notoriously difficult to measure by volume — a packed cup can contain 50g more flour than a spooned cup. A scale gives you the same result every single time.
• Add a tap of the tray mid-bake. — At the 8-minute mark, lift the tray 5cm off the rack and drop it firmly onto the oven shelf. This deflates any large air bubbles and encourages the edges to crinkle — a visual signal of a chewy, dense interior.
• Bake one tray at a time on the middle rack. — Two trays stacked in the oven create uneven heat: the bottom tray gets a pale, underbaked base while the top tray over-browns. One tray, middle rack, every time.
• Pull early, rest on the tray. — The 5 minutes of carry-over cooking on the hot tray finish the centre. Cookies that look done in the oven will be overbaked and hard once cooled.
• Store with a slice of white bread. — A slice of white bread in the cookie tin draws moisture and keeps the cookies soft for an extra 1 to 2 days past the point they would normally start to firm up.
• For a thicker cookie, chill the balls. — After scooping, refrigerate the portioned balls for 15 minutes before baking. This is especially useful in a warm kitchen where the dough has softened.
• Doubling: — Doubles cleanly. Use the largest bowl you have for the oat fold — 270g of oats is a significant volume. Bake in separate batches rather than stacking trays.

Common Mistakes to Avoid

These are the six errors that reliably ruin oatmeal cookies — and the exact fix for each one.

❌ Using Warm Butter

Result: Your cookies will spread flat and thin in the oven — the fat is already liquid when the dough hits the heat, so nothing holds the ball shape.
Fix: After browning, wait at least 15 minutes before adding sugar. The butter should be warm but not hot — if you can hold your palm near the bowl without discomfort, it is ready.

❌ Skipping the Dough Chill

Result: Flat, thin, wide cookies that spread across the tray and lose their thickness before the edges can set.
Fix: Chill for 30 minutes minimum. If you are in a hurry, put the entire bowl in the freezer for 12 minutes — this achieves the same result.

❌ Overbaking Past Set Edges

Result: Hard, dry cookies that lose their chew within hours of baking — the excess baking time drives out the moisture the brown sugar worked to keep.
Fix: Pull the tray when the edges are set and golden but the centre still looks slightly underdone. The 5-minute rest on the hot tray finishes them.

❌ Measuring Flour by Scooping

Result: Up to 25% too much flour, which produces a stiff, dry dough that bakes into a dense cookie with no chew.
Fix: Spoon flour into your measuring cup from the bag and level off with a straight edge — or weigh it at 190g.

❌ Using Quick Oats Instead of Rolled Oats

Result: A smooth, uniform, soft cookie with no visible oat texture — closer to a soft drop cookie than a classic oatmeal cookie.
Fix: Use rolled oats (old-fashioned oats) for the texture this recipe is built around. If quick oats are your only option, reduce the quantity to 240g and chill the dough for 45 minutes.

❌ Packing Trays Too Close Together

Result: Cookies that spread into each other, fuse at the edges, and bake unevenly — the centre of the tray gets less airflow and the cookies there bake slower than the ones near the edges.
Fix: Space cookies at least 5cm apart. 12 cookies per standard tray is the maximum for 2-tablespoon balls.

Variations Worth Trying

The base recipe is a reliable framework. Each of these variations requires a single change at one specific point in the process.

Oatmeal Raisin Cookies

What changes: Replace the 150g of chocolate chips with 150g of raisins. For softer, plumper raisins, soak them in warm water for 10 minutes and pat dry before adding.
When: At Step 5.
Result: The classic American oatmeal cookie — sweet, spiced, and slightly sticky inside. The raisins add a soft chewiness that contrasts with the oat texture.

Chocolate Chip Oatmeal Cookies

What changes: Use 150g of semi-sweet chocolate chips as your mix-in. For a bakery-style finish, press 5 to 6 extra chips onto the top of each ball before baking — these show up visually in photos and give a more generous chocolate-to-oat ratio on the surface.
When: At Step 5 and just before baking.
Result: The most popular variation — warm chocolate pockets against the chewy oat base.

Vegan Oatmeal Cookies

What changes: Replace butter with a vegan butter block (not spread) at 1:1. Skip the browning step — vegan butter does not brown the same way. Replace each egg with a flax egg: 1 tablespoon ground flaxseed + 3 tablespoons water, rested 5 minutes per egg.
When: At Step 1 (melt instead of brown) and Step 3.
Result: A slightly denser, more uniform cookie with a flatter spread. Increase the chill time to 45 minutes to compensate for the higher water content in vegan butter.

Gluten-Free Version

What changes: Replace plain flour with a GF plain flour blend at 1:1. Add ½ teaspoon xanthan gum if your blend does not already contain it. Verify your oats are certified gluten-free (oats are naturally GF but are often processed in facilities with wheat).
When: At Step 4.
Result: A slightly more crumbly cookie that benefits from a longer chill — 45 to 60 minutes — to hold its shape better during baking. The flavour is essentially identical.

Salted Caramel Oatmeal Cookies

What changes: Replace 150g of mix-ins with 100g of caramel chips and 50g of chopped pecans. After baking and cooling, drizzle with 2 tablespoons of melted caramel sauce. Finish with a pinch of flaky sea salt on top while the caramel is still warm.
When: Mix-ins at Step 5; drizzle and salt after cooling.
Result: An elevated, occasion-worthy cookie — the buttery caramel and salt create a more complex flavour against the cinnamon-spiced oat base.

How to Store

Room Temperature

Baked oatmeal cookies keep for best quality for up to 5 days at room temperature in an airtight container. Store with a slice of white bread — the bread slowly releases moisture into the container, which keeps the cookies soft for 1 to 2 days longer than they would last without it. Replace the bread slice every 2 days. What degrades first at room temperature is the chew — the cookies gradually firm up and become crisper as the moisture evaporates. Keep away from direct heat and sunlight.

Refrigerator

Refrigerating baked cookies is generally not recommended — the cold air dries out the crumb faster than room-temperature storage. If you must refrigerate (in very warm weather), use an airtight container and bring cookies to room temperature for 15 minutes before eating. Cold oatmeal cookies feel harder and drier than they actually are — the fat in the cookie firms up in the cold, which makes the texture seem stiffer. Best quality for up to 7 days refrigerated. For unbaked dough, refrigerate in the bowl, tightly covered, for up to 3 days.

Freezer — Complete Guide

Can it be frozen? Yes — both baked cookies and unbaked dough balls freeze very well.

Baked cookies: Cool completely. Layer in an airtight container with parchment between layers. Freeze for best quality for up to 3 months. Thaw at room temperature for 30 minutes, or microwave for 15 seconds to restore the just-baked warmth.

Unbaked dough balls: Scoop into balls and freeze on a lined tray until solid — about 2 hours. Transfer to a zip-lock freezer bag. Label with the date. Freeze for best quality for up to 3 months. Bake straight from frozen at the same temperature, adding 2 to 3 extra minutes.

Texture note: Baked cookies thaw with very little noticeable texture change — the high oat content helps them hold up better than many other cookies. The brown sugar keeps the crumb from drying out during freezing. Use your judgment — if they smell off or show mould, discard them.

If batch baking and freezing ahead is part of your routine, this recipe is one of the best candidates for a large-batch freeze.

How to Serve

Classic Ways to Serve

• Warm from the oven — reheat individual cookies in a 150°C oven for 3 minutes to restore the just-baked texture
• With a cold glass of whole milk — the fat in the milk cuts the sweetness and complements the cinnamon spice note
• As a lunchbox cookie — pack individually wrapped once fully cooled for clean transport without sticking

Upgraded and Occasion-Worthy

• Ice cream sandwich — press a scoop of vanilla bean ice cream between two cookies; freeze for 15 minutes to firm up before serving
• Cookie platter for gifting — stack the salted caramel variation alongside the raisin and chocolate chip versions; wrap in cellophane with a ribbon and include the storage note
• Cookie and coffee pairing — the brown butter and cinnamon notes pair exceptionally well with a flat white or a pour-over coffee with medium roast beans

Oatmeal cookies work as a weeknight bake, a school treat, or a gift — the flavour profile is crowd-neutral enough to serve to anyone. Best served within 48 hours of baking when the interior is at its softest.

Frequently Asked Questions

Can I make oatmeal cookies without eggs?

Yes — you can make oatmeal cookies without eggs by substituting 1 flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, rested 5 minutes) per egg. The cookies will spread slightly more and have a denser, chewier texture than the original. A ripe mashed banana (60g) also works as a substitute and adds a faint natural sweetness.

Why did my oatmeal cookies turn out flat?

Flat oatmeal cookies are almost always caused by warm or melted butter that was not cooled before mixing, or by skipping the dough-chilling step. Warm butter causes the fat to spread before the structure sets in the oven. Chill your dough for at least 30 minutes before baking — this firms the butter and gives you a thicker, puffier cookie. Also check that your baking soda is fresh: old baking soda loses its lift.

How do I know when oatmeal cookies are done?

Oatmeal cookies are done when the edges are set and lightly golden, but the centre still looks slightly underdone and glossy. They will continue to firm up on the hot tray for 5 minutes after you pull them from the oven. Pulling them early — before the edges are fully set — is the correct move for a chewy centre. Waiting until the centre looks fully baked produces a crisp, dry cookie.

Can I make oatmeal cookie dough ahead of time?

Yes — oatmeal cookie dough keeps well in the refrigerator for up to 3 days, tightly covered, and can be frozen as portioned balls for up to 3 months. Chilled dough actually bakes better than fresh dough: the resting time allows the oats to fully hydrate and the brown sugar to deepen in flavour. Bake straight from the freezer — add 2 to 3 minutes to the bake time. If you enjoy other make-ahead cookie dough recipes, the same freezer method applies across most drop cookie doughs.

How long do oatmeal cookies last?

Oatmeal cookies keep for best quality for up to 5 days at room temperature in an airtight container. Adding a slice of white bread to the container draws excess moisture and helps the cookies stay soft for longer. Refrigerating them dries out the crumb and is not recommended unless the weather is very warm. Use your judgment — if they smell off or show mould, discard them.

Can I freeze oatmeal cookies?

Yes — both baked oatmeal cookies and unbaked dough balls freeze well. For baked cookies: cool completely, layer with parchment in an airtight container, and freeze for best quality for up to 3 months. For dough: portion onto a lined tray, freeze until solid (about 2 hours), then transfer to a freezer bag. Bake from frozen at the same temperature, adding 2 to 3 minutes.

What can I substitute for brown sugar in oatmeal cookies?

The best substitute for brown sugar in oatmeal cookies is coconut sugar at a 1:1 ratio — it has a similar molasses depth and keeps the crumb moist. White granulated sugar works at a 1:1 swap but produces a crispier, less chewy cookie that dries out faster. Honey or maple syrup can replace brown sugar at ¾ the quantity, but reduce other liquids slightly and expect a softer, flatter spread.

Can I double this recipe?

Yes — this recipe doubles straightforwardly. Mix in a large bowl to give the oats room to fold in without overflow. Bake one tray at a time on the middle rack rather than stacking two trays — stacked trays create uneven heat that results in pale, underbaked bottoms on the lower tray. Chilling time stays the same.

Why did my oatmeal cookies turn out hard?

Hard oatmeal cookies are caused by overbaking, using too much flour, or not enough brown sugar. Overbaking is the most common cause — pull the cookies when the edges are set but the centre still looks slightly underdone. Too much flour creates a stiff dough that bakes hard. Measure flour by spooning into the cup and levelling off, not by scooping directly from the bag.

What size should oatmeal cookies be?

For the chewy, thick style in this recipe, use a 2-tablespoon scoop (about 45g per ball) — this produces a cookie roughly 7 to 8cm in diameter after baking. Smaller balls (1 tablespoon) bake in 8 to 10 minutes and produce a thinner, crispier result. Larger balls (3 tablespoons) need 14 to 16 minutes and give you a bakery-style oversized cookie with a soft centre.

Should I use quick oats or rolled oats for oatmeal cookies?

Rolled oats (old-fashioned oats) are the correct choice for this recipe — they give you visible oat texture, a slightly chewy bite, and hold their structure through baking. Quick oats absorb more liquid and produce a smoother, more uniform cookie that is closer to a soft drop cookie than a classic oatmeal cookie. Steel-cut oats are too coarse and do not soften enough during the bake time.

Can I add raisins to oatmeal cookies?

Yes — raisins are the most classic oatmeal cookie add-in. Fold in 150g of raisins at the same point you would add chocolate chips, right before chilling the dough. For softer, plumper raisins, soak them in warm water for 10 minutes and pat dry before adding — this stops them from pulling moisture from the cookie during baking and keeps them tender rather than chewy.
