Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
  • In a large bowl, mix melted butter, granulated sugar, and egg yolks until smooth and creamy.
  • Sift in the flour and pinch of salt, folding gently until just combined. Don’t overmix—this will keep the cake tender!
  • Pour the batter into your prepared cake pan and bake for about 25 minutes, or until a toothpick inserted into the center comes out clean. Let it cool completely before assembling.

Prepare the Dark Chocolate Mousse

  • Using a double boiler, melt the dark chocolate over low heat until smooth, then let it cool slightly.
  • In a separate bowl, whip 1/2 cup heavy cream to soft peaks.
  • In another bowl, beat the egg whites until stiff peaks form.
  • Gently fold the whipped cream into the cooled chocolate mixture, followed by the beaten egg whites, being careful not to deflate the mixture.

Prepare the Milk Chocolate Mousse

  • Follow the same method as for the dark chocolate mousse, this time with milk chocolate. Set aside.

Prepare the White Chocolate Mousse

  • Again, use the same method with white chocolate and fold in the vanilla extract for added flavor.

Assemble the Cake

  • Once the cake base has cooled, layer the dark chocolate mousse on top, spreading evenly.
  • Next, add the milk chocolate mousse, and finally top with the white chocolate mousse.
  • Smooth the top and refrigerate for at least 4 hours, or until set.

Serve

  • Once set, carefully remove the cake from the pan. Dust with powdered sugar and slice to serve chilled.
  • Enjoy each heavenly layer!

Notes

Use room-temperature butter and eggs for better mixing. Chill bowls and whisks before whipping cream for optimal fluffiness.
