Method

Step 1 – Bake the Cupcakes

1. Preheat oven to 180°C / 350°F. Line a 12-hole cupcake tray with cases.

5. Alternate adding dry ingredients and milk into the butter mixture, mixing gently until combined. 
6. Divide batter evenly into cupcake cases. 
7. Bake for 18–20 minutes until golden and springy. 
8. Cool completely before frosting. 

Step 2 – Make the Biscoff Buttercream

1. Beat softened butter until pale and creamy. 
2. Add powdered sugar gradually, mixing until smooth. 
3. Beat in Biscoff spread until fully combined. 
4. If too thick, add 1–2 tbsp milk for a silky, pipeable consistency. 

Step 3 – Decorate

2. Top each with a mini Biscoff biscuit. 
3. Sprinkle crushed biscuits for extra crunch. 

Tips for Perfect Biscoff Cupcakes

• Use room temperature ingredients for a smooth batter.
