Ingredients
- 6 oz, chopped bittersweet chocolate
- 6 oz, chopped milk chocolate
- 3 cups, divided heavy cream
- 1/2 cup granulated sugar
- 4 egg yolks
- 1 tbsp gelatin powder
- 3 tbsp cold water
- 2 tbsp, softened unsalted butter
- 2 tbsp, for dusting cocoa powder
Instructions
- Step 1: Sprinkle 1 tbsp gelatin powder over 3 tbsp cold water in a small bowl and let bloom for 5 minutes.
- Step 2: Heat 1 cup heavy cream with 1/4 cup granulated sugar in a saucepan over medium heat until hot but not boiling. In a separate bowl, whisk 4 egg yolks. Slowly pour hot cream into yolks, whisking continuously to temper. Return mixture to saucepan and cook over low heat, stirring constantly until thickened to a custard consistency, about 5 minutes. Remove from heat and stir in bloomed gelatin until dissolved.
- Step 3: Divide custard evenly; melt 6 oz chopped bittersweet chocolate in one half and 6 oz chopped milk chocolate in the other half, stirring each until smooth. Let cool slightly.
- Step 4: Whip remaining 2 cups heavy cream to soft peaks. Fold half the whipped cream gently into bittersweet chocolate custard and the other half into milk chocolate custard.
- Step 5: In a springform pan, pour and smooth the bittersweet chocolate mousse layer. Chill in refrigerator for 1 hour until set. Then pour the milk chocolate mousse layer on top and chill for another 2 hours.
- Step 6: Melt 4 oz bittersweet chocolate with 2 tbsp unsalted butter over a double boiler, stirring to a glossy ganache. Pour ganache over chilled mousse cake and smooth evenly. Dust lightly with 2 tbsp cocoa powder before serving.
