For the brownie layer
- 200 g unsalted butter, plus extra to grease
- 125 g dark chocolate (70% cocoa solids), chopped
- 4 medium eggs, lightly beaten
- 300 g caster sugar
- 100 g plain flour
- 40 g cocoa powder
For the peppermint cream
- 1 medium egg white
- 2 tsp. peppermint extract
- 200 g icing sugar
- Green food colouring paste (optional)
- 200 g dark chocolate (70% cocoa solids), chopped
- Step 1Preheat oven to 190°C (170°C fan) mark 5. Grease and line a 20.5cm square tin with baking parchment.
- Step 2For the brownie layer, melt butter with 125g dark chocolate in a medium bowl set over a pan of simmering water. Remove bowl from heat, cool for 1min, then stir in remaining brownie ingredients. Scrape into prepared tin and bake for 18-20min until just firm to the touch. Cool completely in tin.
- Step 3Meanwhile, make the peppermint cream layer. In a medium bowl, using a whisk, whisk together the egg white and peppermint essence together until frothy. Sift over the icing sugar and mix with a wooden spoon until combined. Add a little food colouring, if using, and mix until combined. Scrape peppermint mixture onto brownie and spread to cover. Set aside.
- Step 4Melt remaining 200g chocolate in a clean bowl set over simmering water. Leave to cool to room temperature then pour over the peppermint cream layer and tilt the tin to spread the chocolate so it forms an even layer. Chill until, around 45min. To serve, transfer to a board and slices into squares.
