Ingredients

Scale
  • 1 cup all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, softened
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup buttermilk
  • 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
  • Whipped cream (for garnish)
  • Chocolate shavings (for garnish)

Instructions

  1. Make the Cake: Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round cake pan. In a bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Set aside. In a large mixing bowl, cream the softened butter and sugar together until light and fluffy. Beat in the eggs one at a time, followed by the vanilla extract. Gradually add the dry ingredients to the wet mixture, alternating with the buttermilk. Mix until just combined. Pour the batter into the prepared cake pan and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely in the pan.
  2. Prepare the Mousse: In a heatproof bowl, melt the chopped chocolate and butter together over a pot of simmering water, stirring until smooth. Remove from heat and let cool slightly. In a separate bowl, beat the egg whites until soft peaks form. Gradually add the sugar and continue beating until stiff peaks form. Stir the egg yolks into the cooled chocolate mixture until well combined. Gently fold the whipped egg whites into the chocolate mixture until no white streaks remain. In another bowl, whip the heavy cream and vanilla extract until soft peaks form. Fold the whipped cream into the chocolate mixture until fully incorporated.
  3. Assemble the Cake: Once the cake has cooled, carefully slice it in half horizontally. Place one layer on a serving plate and spread half of the chocolate mousse over it. Top with the second layer and spread the remaining mousse on top. Refrigerate the cake for at least 240 minutes, or until the mousse is set.
  4. Garnish and Serve: Before serving, garnish the top with whipped cream and chocolate shavings. Slice and enjoy your decadent chocolate mousse cake!

Notes

Make sure your ingredients are at room temperature for the best results. Don’t skip chilling the cake; it helps the mousse set properly. Use high-quality chocolate for a richer flavor.
