Units Scale

For the brownie base:

  • 1/2 cup unsalted butter
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/3 cup unsweetened cocoa powder
  • 1/2 cup all-purpose flour
  • 1/4 teaspoon salt

For the dark chocolate mousse:

  • 6 oz dark chocolate (chopped)
  • 1 cup heavy cream (divided)
  • 1 teaspoon vanilla extract

For the milk chocolate mousse:

  • 6 oz milk chocolate (chopped)
  • 1 cup heavy cream (divided)
  • 1/2 teaspoon vanilla extract

For the white chocolate mousse:

  • 6 oz white chocolate (chopped)
  • 1 cup heavy cream (divided)
  • 1/2 teaspoon vanilla extract

Instructions

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
