Ingredients:
For the Cake Base:
- 1 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1 cup granulated sugar
- 1/2 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened
- 2 large eggs
- 1/2 cup buttermilk
- 1/2 cup boiling water
- 1 teaspoon vanilla extract
For the Chocolate Mousse:
- 8 oz (225g) semi-sweet chocolate, chopped
- 2 cups heavy cream
- 1/4 cup granulated sugar
- 1 teaspoon vanilla extract
- 3 large egg yolks
For the Ganache:
- 6 oz (170g) semi-sweet chocolate, chopped
- 1/2 cup heavy cream
For Garnishing:
- Whipped cream, for topping
- Chocolate shavings or fresh berries, optional
Instructions:
- Prepare the Cake Base: Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round cake pan, or line it with parchment paper.
- Mix Dry Ingredients: In a medium bowl, whisk together the flour, cocoa powder, granulated sugar, baking powder, baking soda, and salt.
- Cream Butter and Eggs: In a large bowl, beat the softened butter until creamy. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
- Combine Ingredients: Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk. Mix until just combined. Stir in the boiling water until the batter is smooth and well combined.
- Bake the Cake: Pour the batter into the prepared cake pan. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
- Prepare the Chocolate Mousse: In a heatproof bowl, melt the chopped semi-sweet chocolate over a pot of simmering water or in the microwave in short intervals, stirring until smooth. Let the melted chocolate cool slightly.
- Whip Cream and Combine: In a separate bowl, whip the heavy cream and granulated sugar until soft peaks form. Gently fold the whipped cream into the cooled melted chocolate. In another bowl, beat the egg yolks until thick and pale. Fold the beaten egg yolks into the chocolate mixture.
- Assemble the Cake: Place the cooled cake base on a serving plate. Spread a layer of the chocolate mousse evenly over the top of the cake. Refrigerate the cake while you prepare the ganache.
- Prepare the Ganache: Heat the heavy cream in a small saucepan until it begins to simmer. Pour the hot cream over the chopped chocolate in a bowl. Let it sit for a few minutes, then stir until smooth and glossy.
- Top the Cake: Pour the ganache over the chilled mousse layer, spreading it evenly with a spatula. Return the cake to the refrigerator and chill for at least 4 hours, or until set.
- Garnish and Serve: Before serving, top the cake with whipped cream and garnish with chocolate shavings or fresh berries if desired.
Tips:
- Room Temperature Ingredients: Ensure the butter and eggs are at room temperature for a smoother batter and better texture.
- Avoid Overmixing: When combining ingredients, mix until just combined to avoid a dense cake.
- Cool Cake Completely: Allow the cake to cool completely before adding the mousse to prevent melting.
- Chill Thoroughly: Make sure to chill the cake thoroughly to set the mousse and ganache properly.
