Ingredients
Scale
For the brownie base:
- ½ cup unsalted butter (melted)
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- ⅓ cup unsweetened cocoa powder
- ½ cup all-purpose flour
- ¼ teaspoon salt
For the dark chocolate mousse:
- 6 oz dark chocolate (chopped)
- 1 cup heavy cream (divided)
- 1 teaspoon unflavored gelatin
- 1 tablespoon water
For the milk chocolate mousse:
- 6 oz milk chocolate (chopped)
- 1 cup heavy cream (divided)
- 1 teaspoon unflavored gelatin
- 1 tablespoon water
For the white chocolate mousse:
- 6 oz white chocolate (chopped)
- 1 cup heavy cream (divided)
- 1 teaspoon unflavored gelatin
- 1 tablespoon water
Instructions
- Make the brownie base: Preheat oven to 350°F (175°C). Grease and line the bottom of a 9-inch springform pan. In a medium bowl, whisk together the melted butter and sugar. Add the eggs and vanilla and whisk until smooth. Stir in cocoa powder, flour, and salt just until combined. Pour into the pan and smooth the top. Bake for 18–20 minutes or until set. Let cool completely.
- For each mousse layer: In a small bowl, sprinkle gelatin over water and let bloom for 5 minutes. Heat ¼ cup of heavy cream until just simmering. Remove from heat and stir in the bloomed gelatin until dissolved. Pour the hot cream mixture over chopped chocolate in a bowl and stir until smooth. Whip the remaining ¾ cup heavy cream to soft peaks. Fold into the chocolate mixture gently until combined.
- Assembly: Once the brownie base is fully cooled and still in the pan, spread the dark chocolate mousse evenly over it. Chill for 20–30 minutes until slightly firm. Repeat with the milk chocolate mousse, followed by the white chocolate mousse, chilling briefly between layers. Once fully assembled, chill the cake for at least 4 hours or overnight to set completely. Run a warm knife around the edges before releasing the springform pan. Serve chilled.
Notes
- Use high-quality chocolate for best flavor and texture.
- To smooth each mousse layer, tap the pan gently on the counter.
- Garnish with chocolate curls or cocoa powder before serving.
