Method
- Preheat and prepare. Set oven to 350°F (175°C). Line an 8×8-inch metal pan with parchment, leaving a 2-inch overhang on two sides. Grease the parchment lightly.
- Make the brownie batter. Whisk melted butter and sugar until combined and slightly glossy. Add eggs and vanilla; whisk 20 strokes. Sift in cocoa powder, flour, salt, and baking powder. Fold with a rubber spatula just until no dry streaks remain. Do not overmix.
- Make the pumpkin layer. In a separate bowl, whisk pumpkin purée, egg, sugar, cinnamon, nutmeg, cloves, and vanilla until smooth, uniform in color, and visibly spiced.
- Layer and swirl. Pour three-quarters of the brownie batter into the prepared pan and spread evenly. Drop the pumpkin mixture in 6 to 8 spoonfuls across the surface. Add the remaining brownie batter in small dollops between the pumpkin mounds. Use a butter knife to draw 4 to 6 wide S-strokes through the layers. Stop there.
- Bake. Bake on the center rack for 30 to 35 minutes. Start checking at 28 minutes — a toothpick inserted 1 inch from center should come out with a few moist crumbs, not wet batter.
- Cool and slice. Cool in the pan on a wire rack for at least 1 hour. Lift using the parchment overhang. Slice into 16 squares with a sharp knife, wiping the blade clean between each cut.
Notes
Flour and cocoa: always spoon and level — never scoop from the bag
• Pumpkin purée: if the canned purée looks watery, drain through a strainer for 10 minutes before using
• Pan: metal 8×8-inch gives the most consistent, even results
• Swirl: 4 to 6 strokes maximum — stop before the layers blend together
• Storage: airtight container — 3 days room temp / 6 days refrigerator / 3 months freezer
