Ingredients
UnitsScale
For the brownie base:
1/2cup unsalted butter
1cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
1/3cup unsweetened cocoa powder
1/2cup all-purpose flour
1/4 teaspoon salt
For the dark chocolate mousse:
6oz dark chocolate (chopped)
1cup heavy cream (divided)
1 teaspoon vanilla extract
For the milk chocolate mousse:
6oz milk chocolate (chopped)
1cup heavy cream (divided)
1/2 teaspoon vanilla extract
For the white chocolate mousse:
6oz white chocolate (chopped)
1cup heavy cream (divided)

Instructions
Make the brownie base: In a medium saucepan, melt butter over low heat. Remove from heat and stir in sugar, eggs, and vanilla. Add cocoa powder, flour, and salt; mix until just combined. Spread batter into the pan and bake for 20–22 minutes or until a toothpick inserted comes out with moist crumbs. Cool completely.
Make the dark chocolate mousse: Melt dark chocolate with ¼ cup cream in a heatproof bowl over simmering water, stirring until smooth. Let cool. Whip remaining ¾ cup cream to stiff peaks and fold into the cooled chocolate mixture. Spread over the brownie base and chill for 20–30 minutes.
Make the milk chocolate mousse: Repeat the same process with the milk chocolate and cream. Spread gently over the set dark chocolate layer. Chill again for 20–30 minutes.
Make the white chocolate mousse: Repeat with white chocolate and cream, then spread over the milk chocolate layer. Chill the completed cake for at least 4 hours or overnight until fully set.
When ready to serve, run a knife around the edge of the pan and release the springform ring. Garnish with chocolate shavings, curls, or cocoa powder if desired.
Notes
Use high-quality chocolate for best texture and flavor.
To speed up setting time, chill in the freezer for 1 hour before refrigerating.
For clean slices, dip a sharp knife in hot water and wipe dry between cuts.
