Ingredients

Scale

Chocolate Cake

  • 1 cup all-purpose flour
  • 1 cup granulated sugar
  • 6 tablespoons unsweetened cocoa powder
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup buttermilk
  • 1/4 cup vegetable oil
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 cup hot water

Chocolate Mousse

  • 6 ounces semisweet chocolate, chopped
  • 3 large eggs, separated
  • 1/4 cup granulated sugar
  • 1 cup heavy cream, whipped to soft peaks

Cream Topping

  • 1/2 cup heavy cream
  • 1 tablespoon powdered sugar
  • 1/2 teaspoon vanilla extract

Instructions

  1. Prepare the Chocolate Cake: Preheat your oven to 350°F (175°C). In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Add the buttermilk, oil, egg, and vanilla, mixing until smooth. Gradually stir in the hot water. Pour the batter into a greased 8-inch round cake pan and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely on a wire rack.
  2. Make the Chocolate Mousse: Melt the chopped semisweet chocolate over a double boiler or in short bursts in the microwave, stirring until smooth. Let it cool slightly. In a clean bowl, beat the egg whites until soft peaks form, gradually adding sugar until stiff and glossy. In a separate bowl, whisk the egg yolks lightly then slowly combine them with the melted chocolate. Gently fold the egg whites into the chocolate mixture to maintain the mousse’s light texture, then fold in the whipped cream carefully until fully incorporated.
  3. Assemble the Cake: Slice the cooled chocolate cake in half horizontally to create two layers. Place the bottom layer on a serving plate. Spread the chocolate mousse evenly over the first layer. Place the second layer on top and chill the assembled cake in the refrigerator for at least 2 hours to set properly.
  4. Prepare the Cream Topping: Whip the heavy cream together with powdered sugar and vanilla extract until soft peaks form. Spread or pipe this cream over the chilled mousse layer just before serving for an extra creamy finish.

Notes

  • Ensure the cake is completely cooled before layering mousse to prevent melting.
  • Use fresh eggs and consume mousse within 1-2 days as it contains raw eggs.
  • Chilling the mousse cake helps it set and enhances flavor melding.
  • You can substitute buttermilk with milk plus 1 tablespoon vinegar or lemon juice.
  • Use high-quality chocolate for the richest flavor.
