Easy Chocolate Mousse Cake Recipe

This cake features a moist chocolate sponge base topped with a luscious chocolate mousse. The preparation takes about 1 hour, plus chilling time, and serves 8-10 people.

Ingredients

For the Chocolate Sponge Cake:
1 cup all-purpose flour
1/2 cup unsweetened cocoa powder
1 cup granulated sugar
1/2 cup unsalted butter, melted
3 large eggs
1 teaspoon vanilla extract
1 teaspoon baking powder
1/2 teaspoon salt
For the Chocolate Mousse:
8 ounces dark chocolate, chopped
2 cups heavy cream, divided
1/4 cup powdered sugar
1 teaspoon vanilla extract
3 large egg whites
1/4 teaspoon cream of tartar

Instructions

Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round cake pan.
Make the Chocolate Sponge Cake: In a mixing bowl, combine flour, cocoa powder, sugar, baking powder, and salt. In another bowl, whisk together melted butter, eggs, and vanilla. Combine wet and dry ingredients until just mixed. Pour into the prepared pan and bake for 25-30 minutes. Let cool completely.
Prepare the Chocolate Mousse: Melt the dark chocolate in a heatproof bowl over simmering water. In a separate bowl, whip 1 cup of heavy cream with powdered sugar and vanilla until soft peaks form. In another bowl, beat egg whites with cream of tartar until stiff peaks form.
Combine Mousse Ingredients: Gently fold the melted chocolate into the whipped cream, then fold in the egg whites until fully incorporated.
Assemble the Cake: Once the sponge cake is cooled, slice it in half horizontally. Place one layer on a serving plate, spread half of the mousse on top, then add the second layer and top with the remaining mousse. Chill in the refrigerator for at least 4 hours or overnight.
Serve: Slice the cake and serve chilled. Optionally, garnish with chocolate shavings or fresh berries.
