- 6 tablespoons unsalted butter, melted (85g)
- 6 oz bittersweet chocolate (170g), chopped
- 1 cup heavy cream (240ml), chilled
- 3 large eggs, separated, at room temperature
- ¼ cup granulated sugar (50g)
- 5 oz milk chocolate (140g), chopped
- ¾ cup heavy cream (180ml), chilled
- 2 large eggs, separated, room temperature
- 3 tablespoons granulated sugar (38g)
- 5 oz white chocolate (140g), chopped
- ¾ cup heavy cream (180ml), chilled
- 2 large eggs, separated, room temperature
- 2 tablespoons granulated sugar (25g)
- Optional garnishes: fresh berries (raspberries or strawberries), cocoa powder or chocolate shavings, mint leaves
Instructions
- Prepare the crust: Mix the chocolate cookie crumbs with melted butter until evenly combined. Press this mixture firmly into the bottom of a 9-inch springform pan to form an even layer. Chill in the refrigerator for at least 15 minutes.
- Make the dark chocolate mousse: Melt the bittersweet chocolate gently over a double boiler or in the microwave in 30-second bursts. Set aside to cool slightly.
- Whip 1 cup heavy cream until soft peaks form; chill in the fridge.
- Whisk egg yolks with half the sugar until pale and slightly thickened.
- Whisk egg whites in a clean bowl until soft peaks form, gradually add remaining sugar, and whip until glossy stiff peaks appear.
- Fold melted chocolate into the yolk mixture carefully.
- Gently fold in whipped cream, then fold in egg whites last to keep mousse airy.
- Pour mousse over chilled crust and smooth the top. Chill for 20 minutes.
- Make the milk chocolate mousse: Repeat melting and whipping process with milk chocolate, cream, egg yolks, and egg whites using the same folding technique.
- Pour milk chocolate mousse over set dark chocolate layer and smooth. Chill for 20 minutes.
- Make the white chocolate mousse: Repeat the process with white chocolate and respective cream, eggs, and sugar.
- Pour white chocolate mousse over milk chocolate layer and smooth gently.
- Cover cake loosely with plastic wrap and refrigerate for at least 4 hours or overnight to set fully.
- Before serving, run a knife around the pan edge, unlock the springform, and transfer cake to a serving plate. Garnish as desired.
Notes
Use room temperature eggs to avoid curdling. Melt chocolate gently to prevent burning. Whip cream to soft peaks and egg whites to stiff peaks for best texture. Chill between layers to prevent mixing. For dairy-free version, substitute heavy cream with coconut cream and use aquafaba for egg whites. Use pasteurized eggs or substitutes for safety if desired. Chill cake overnight for best flavor and texture. Use a hot knife dipped in water for clean slices.
