Instructions
Step 1 – Prepare the Brownie Base:
Preheat oven to 350°F (175°C). Melt butter and dark chocolate together in a heatproof bowl over a water bath. Stir until smooth, then remove from heat. Add sugar, eggs, flour, cocoa powder, and salt. Mix just until combined. Pour into a lined 9-inch (23 cm) springform pan and bake for 20–25 minutes. Cool completely.
Step 2 – Make the Dark Chocolate Mousse:
Melt dark chocolate and set aside to cool slightly. Whip heavy cream until soft peaks form. In a separate bowl, beat egg whites with sugar until stiff peaks form. Fold the melted chocolate into the whipped cream, then gently fold in the egg whites. Spread over the cooled brownie base and refrigerate for 30 minutes to set.
Step 3 – Make the Milk Chocolate Mousse:
Repeat the same process using milk chocolate. Once the dark mousse is slightly firm, gently spread the milk chocolate mousse on top. Smooth the surface and refrigerate for at least 4 hours or overnight until fully set.
Step 4 – Decorate and Serve:
Before serving, garnish with chocolate curls, cocoa powder, or berries. Slice with a warm knife for clean layers and enjoy the ultimate chocolate experience.
