2 large eggs
120ml (½ cup) milk
1 ½ tsp baking powder
1 tsp vanilla extract
Pinch of salt

For the Biscoff Buttercream Frosting:

150g (? cup) unsalted butter, softened
200g (1 ½ cups) powdered sugar
150g (about ½ cup) Biscoff spread (smooth)
1–2 tbsp milk (to loosen, if needed)

For Topping:

Mini Biscoff biscuits (one per cupcake)
Crushed biscuits for sprinkling (optional)

Method

Step 1 – Bake the Cupcakes

Preheat oven to 180°C / 350°F. Line a 12-hole cupcake tray with cases.
Beat butter and sugar together until light and fluffy.
Add eggs one at a time, then stir in vanilla.
Mix flour, baking powder, and salt in a separate bowl.
Alternate adding dry ingredients and milk into the butter mixture, mixing gently until combined.
Divide batter evenly into cupcake cases.
Bake for 18–20 minutes until golden and springy.
Cool completely before frosting.

Step 2 – Make the Biscoff Buttercream

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

Step 3 – Decorate

Pipe swirls of Biscoff buttercream onto cooled cupcakes.
Top each with a mini Biscoff biscuit.
Sprinkle crushed biscuits for extra crunch.

Tips for Perfect Biscoff Cupcakes

Use room temperature ingredients for a smooth batter.
Don’t overbake – cupcakes should be soft and springy.
Chill the frosting slightly before piping for firmer swirls.
Make ahead – cupcakes can be baked the day before and frosted when ready to serve.
