- â…“ cup sugar
- ¼ teaspoon salt
- 1 teaspoon vanilla extract
- ½ cup butter (softened at room temperature)

White Chocolate Mousse

- 1 ½ cups heavy whipping cream
- 1 teaspoon unflavored gelatin

Instructions
- Prepare the Oven and Pan: Preheat your oven to 350°F (175°C). Grease and line a 9-10 inch springform pan with parchment paper to ensure easy removal later.
- Set Up Water Bath: To keep the cake moist during baking, wrap the springform pan tightly in aluminum foil and place it inside a larger pan filled with hot water.
- Melt Chocolate for Cake: Gently melt the 10 oz of semisweet chocolate using a double boiler or microwave to avoid burning.
- Whisk Egg Whites: In a clean bowl, whisk the egg whites with sugar until fluffy, gradually increasing speed until soft peaks form to incorporate air for a light texture.
- Combine Butter, Chocolate, and Egg Yolks: Stir the softened butter into the melted chocolate, then whisk in the egg yolks until smooth.
- Fold Mixtures: Carefully fold the chocolate mixture into the meringue, preserving as much air as possible, then pour batter into the prepared pan.
- Bake Cake Base: Bake for about 28 minutes, or until a toothpick inserted comes out with a few moist crumbs. Allow the cake to cool completely in the pan.
- Dissolve Gelatin for Semisweet Mousse: Soak 1 teaspoon gelatin in 2 tablespoons cool water until dissolved.
- Heat Semisweet Chocolate Mixture: In a saucepan, warm the 10 oz semisweet chocolate and 1 ½ cups heavy whipping cream until smooth and well combined.
- Add Gelatin: Stir in the dissolved gelatin into the warm chocolate mixture, then cool to room temperature.
- Whip Cream and Fold: Whip another 1 ½ cups of heavy cream to soft peaks and gently fold it into the chocolate mixture until smooth.
- Chill Semisweet Mousse: Place the mousse in the refrigerator and chill until firm, approximately 2 hours.
- Dissolve Gelatin for White Chocolate Mousse: Soak 1 teaspoon gelatin in 1 tablespoon cool water until fully dissolved.
- Heat White Chocolate Mixture: Warm 7 oz white chocolate and 1 ½ cups heavy cream together in a saucepan until smooth.
- Add Gelatin to White Chocolate: Stir the dissolved gelatin into the white chocolate mixture and let cool to room temperature.
- Whip Cream and Fold: Whip an additional 1 ½ cups heavy cream to soft peaks and gently fold it into the white chocolate mixture.
- Chill White Chocolate Mousse: Refrigerate until the mousse is firm, about 2 hours.
- Invert Cake Base: Once cooled, carefully remove the cake from the springform pan and invert it onto a serving platter.
- Spread Semisweet Mousse: Evenly spread the chilled semisweet chocolate mousse layer over the cake base.
- Add White Chocolate Mousse Layer: Gently spread the white chocolate mousse evenly on top of the semisweet mousse.
- Chill Assembled Cake: Refrigerate the fully assembled cake for at least 4 hours or until the mousse layers are fully set for perfect slicing.
Notes
- Use high-quality chocolate for the best flavor and texture in both the cake and mousse layers.
- Soaking the springform pan in a water bath helps maintain moisture and prevents cracking during baking.
- Make sure gelatin is fully dissolved and the chocolate mixtures are cooled to room temperature before folding in whipped cream to maintain mousse texture.
- This cake can be made a day ahead to allow flavors to meld and mousse to set perfectly.
- Serve chilled for the best taste and texture.
