Ingredients
Method
- Preheat oven to 170°C / 340°F (150°C fan). Line a 12-cup muffin tin with cupcake liners.
- Whisk the cake flour, baking powder, and salt together in a medium bowl. Set aside.
- Beat softened butter on medium speed for 2 minutes. Add caster sugar and continue beating for a full 3 minutes until the mixture is pale and noticeably lighter in texture.
- Add eggs one at a time, beating 20 seconds after each. Add vanilla extract with the second egg.
- Add flour and buttermilk in three alternating additions (flour, buttermilk, flour, buttermilk, flour), mixing on low speed. Stop the moment you no longer see dry flour streaks.
- Divide batter evenly between the 12 liners, filling each two-thirds full (approximately 55 to 60g per cup). Bake for 18 to 22 minutes until a toothpick comes out clean.
- Cool in the tin for 5 minutes, then transfer to a wire rack. Cool completely — at least 45 minutes — before frosting.
- Beat softened butter for 3 minutes until pale. Add sifted icing sugar in two additions, beating well between each. Add cream one tablespoon at a time until the frosting reaches piping consistency. Beat in vanilla.
- Divide frosting and tint with gel food colouring as desired. Pipe onto cooled cupcakes using a star tip. Decorate immediately with sprinkles and holiday toppers.
Notes
- Cake flour substitute: Use all-purpose flour — expect a slightly firmer crumb.
- Buttermilk substitute: 120ml whole milk + 1½ tsp white vinegar, rested 5 minutes.
- Frosting too stiff? Add cream ½ tsp at a time. Too loose? Add 1 tbsp sifted icing sugar and beat 30 seconds.
- Make ahead: Bake bases up to 2 days ahead; frost on the day of serving.
- Gel colouring: Use "Christmas red" or "super red" for a vivid red — standard red gel can turn coral-pink.
