Ingredients

Scale

For the Chocolate Cake:

  • 1 cup all-purpose flour
  • 1 cup granulated sugar
  • 1/2 cup unsweetened cocoa powder
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter (melted)
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup buttermilk

For the Chocolate Mousse:

  • 8 oz semi-sweet chocolate (chopped)
  • 2 tablespoons unsalted butter
  • 3 large eggs (separated)
  • 1/4 cup granulated sugar
  • 1 cup heavy cream
  • 1 teaspoon vanilla extract
  • Pinch of salt

For Garnish:

  • Whipped cream
  • Chocolate shavings or cocoa powder
  • Fresh berries (optional)

Instructions

  1. Bake the Chocolate Cake: Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round cake pan. In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. In another bowl, mix the melted butter, eggs, vanilla extract, and buttermilk until well combined. Gradually add the wet ingredients to the dry ingredients, stirring until just combined. Pour the batter into the prepared cake pan and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Let it cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely.
  2. Prepare the Chocolate Mousse: In a heatproof bowl over simmering water, melt the chopped chocolate and butter together, stirring until smooth. Remove from heat and let cool slightly. In a separate bowl, whisk the egg yolks and sugar together until pale and fluffy. Gradually add the melted chocolate mixture to the egg yolks, stirring until well combined. In another clean bowl, beat the egg whites with a pinch of salt until stiff peaks form. In a separate bowl, whip the heavy cream and vanilla extract until soft peaks form. Gently fold the whipped egg whites into the chocolate mixture, followed by the whipped cream, until no streaks remain.
  3. Assemble the Cake: Once the chocolate cake has cooled completely, slice it in half horizontally to create two layers. Place one layer of cake on a serving plate. Spread half of the chocolate mousse over the top. Place the second layer of cake on top and spread the remaining mousse over the top and sides of the cake. Refrigerate the cake for at least 2 hours to allow the mousse to set.
  4. Serve: Before serving, garnish with whipped cream, chocolate shavings or cocoa powder, and fresh berries if desired. Slice and serve the Chocolate Mousse Cake chilled for a rich and delightful dessert experience!

Notes

  • Ensure the cake is completely cooled before slicing and adding mousse to prevent melting.
  • Use room temperature eggs for easier whipping and better volume.
  • For a more intense chocolate flavor, use high-quality semi-sweet chocolate.
  • Refrigerate the assembled cake for at least 2 hours, but overnight chilling enhances texture.
  • Fresh berries add a pleasant tart contrast but are optional.
  • When folding in whipped egg whites and cream, do so gently to maintain the mousse’s lightness.
