  • 4 large eggs (room temperature)
  • â…“ cup sugar
  • ¼ teaspoon salt
  • 1 teaspoon vanilla extract
  • ½ cup butter (softened at room temperature)

Semisweet Chocolate Mousse

  • 10 oz high-quality semisweet chocolate (chopped)
  • 1 ½ cups heavy whipping cream
  • 1 teaspoon unflavored gelatin
  • 2 tablespoons cool water

White Chocolate Mousse

  • 7 oz high-quality white chocolate (chopped)
  • 1 ½ cups heavy whipping cream
  • 1 teaspoon unflavored gelatin
  • 1 tablespoon cool water


Instructions

  1. Prepare Cake Pan: Preheat the oven to 350°F (175°C). Grease and line a 9-10 inch springform pan with parchment paper for easy removal.
  2. Set up Water Bath: Wrap the springform pan in aluminum foil to prevent leaks and place it inside a larger pan filled with hot water to create a moist baking environment.
  3. Melt Chocolate: Gently melt the semisweet chocolate over low heat using a double boiler or microwave, stirring frequently to prevent burning.
  4. Whip Egg Whites: In a clean bowl, whisk the egg whites and sugar, starting slowly and increasing speed until soft peaks form, creating a fluffy meringue.
  5. Combine Butter & Yolks: Stir the softened butter into the melted chocolate, then whisk in the egg yolks until smooth.
  6. Fold Batter: Carefully fold the chocolate mixture with the meringue to maintain aeration, then pour the batter into the prepared pan.
  7. Bake Cake: Bake the cake in the water bath for 28 minutes, or until a toothpick inserted comes out with a few moist crumbs. Allow it to cool completely in the pan.
  8. Dissolve Gelatin for Semisweet Mousse: Sprinkle gelatin over 2 tablespoons of cool water and let it bloom for a few minutes.
  9. Heat Chocolate & Cream: In a saucepan, gently heat the semisweet chocolate and 1 ½ cups of heavy whipping cream until smooth and combined.
  10. Add Gelatin: Stir the dissolved gelatin into the warm mixture and allow it to cool to room temperature.
  11. Whip Cream & Fold: Whip the heavy cream to soft peaks and gently fold it into the cooled chocolate mixture until fully incorporated.
  12. Chill Semisweet Mousse: Refrigerate the semisweet mousse until firm, about 2 hours.
  13. Dissolve Gelatin for White Chocolate Mousse: Sprinkle gelatin over 1 tablespoon of cool water and allow it to bloom.
  14. Heat White Chocolate & Cream: In a saucepan, heat the white chocolate and 1 ½ cups of heavy whipping cream until smooth.
  15. Add Gelatin: Stir the dissolved gelatin into the white chocolate mixture and cool to room temperature.
  16. Whip Cream & Fold: Whip the heavy cream to soft peaks and gently fold it into the white chocolate mixture.
  17. Chill White Chocolate Mousse: Refrigerate the white chocolate mousse until firm, about 2 hours.
  18. Assemble Cake Base: Once the cake base is cooled, invert it onto a serving platter removing the parchment paper.
  19. Add Semisweet Mousse: Spread the semisweet chocolate mousse evenly over the cake base.
  20. Add White Chocolate Mousse: Spread the white chocolate mousse layer evenly on top of the semisweet mousse.
  21. Chill Final Cake: Refrigerate the assembled cake for at least 4 hours or until the mousse layers are fully set before serving.

Notes

  • Ensure eggs are at room temperature to achieve better volume when whipping.
  • Using a water bath helps prevent the cake from drying out and maintains moisture.
  • Fold the mixtures gently to preserve the airy texture of the mousse layers.
  • Use high-quality chocolate for the best flavor and smooth texture.
  • Gelatin is essential to set the mousse layers firmly; ensure it is fully dissolved before mixing.
  • Refrigerate the cake well before slicing to maintain clean, defined layers.
