Ingredients

Scale

For the Sponge:

200g butter, softened
200g caster sugar
4 large eggs
1 tsp vanilla extract
200g self-raising flour
30g cocoa powder
2 tbsp milk

For the Mint Buttercream:

150g butter, softened
300g icing sugar
1 tsp peppermint extract (or to taste)
Green food colouring (optional)

For the Topping:

2 x 45g Mint Aero bars, chopped

Instructions

Preheat the oven to 180°C (fan). Grease and line a 20x30cm baking tin.
Cream the butter and caster sugar until light and fluffy.
Beat in the eggs, one at a time, then stir in the vanilla extract.
Fold in the self-raising flour and cocoa powder, then mix in the milk to loosen the batter.
Spread the batter evenly in the tin and bake for 20–25 minutes until springy to the touch. Cool completely.
Prepare the buttercream by beating the butter until smooth. Gradually add icing sugar, then mix in peppermint extract and a drop of green food colouring if desired.
Spread the mint buttercream over the cooled sponge.
Scatter the chopped Mint Aero bars on top.
Drizzle melted chocolate over the traybake for a decadent finish.
Slice into 12 squares and serve!
