Ingredients
Scale
For the Cake Layer
- 1 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 3/4 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 2 large eggs
- 3/4 cup granulated sugar
- 1/2 cup brown sugar
- 1/2 cup vegetable oil
- 1 teaspoon vanilla extract
- 1/2 cup buttermilk
- 1/2 cup hot coffee
For the Mousse Layer
- 1 1/2 cups semi-sweet chocolate chips
- 2 cups heavy whipping cream, divided
- 2 tablespoons powdered sugar
- 1 teaspoon vanilla extract
For the Ganache Topping
- 1/2 cup semi-sweet chocolate chips
- 1/4 cup heavy cream
Instructions
- Prepare the Cake Batter: Preheat your oven to 350°F. Grease and line an 8-inch springform pan with parchment paper. In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, baking powder, and salt until evenly combined. In a separate large bowl, beat the eggs, granulated sugar, brown sugar, vegetable oil, and vanilla extract until smooth and creamy. Stir in the buttermilk. Gradually add the dry ingredients to the wet ingredients and mix gently. Finally, stir in the hot coffee until the batter is smooth and well combined.
- Bake the Cake: Pour the batter into the prepared springform pan. Bake in the preheated oven for 25 to 30 minutes or until a toothpick inserted into the center of the cake comes out clean. Remove from the oven and let the cake cool completely in the pan on a wire rack.
- Make the Chocolate Mousse: Melt 1 1/2 cups of semi-sweet chocolate chips with 1/2 cup heavy cream in a heatproof bowl over simmering water or by microwaving in short bursts, stirring until smooth. Allow this chocolate mixture to cool slightly. In a separate chilled bowl, whip the remaining 1 1/2 cups heavy whipping cream with powdered sugar and vanilla extract until soft peaks form. Gently fold the melted chocolate mixture into the whipped cream until fully combined to create a light, fluffy mousse.
- Assemble the Cake: Spread the chocolate mousse evenly over the cooled cake layer inside the springform pan. Cover and refrigerate for at least 4 hours to allow the mousse to set and firm up.
- Prepare the Ganache Topping: Heat 1/4 cup heavy cream until warm but not boiling. Pour the warm cream over 1/2 cup semi-sweet chocolate chips and let sit for 2 minutes. Stir the mixture until smooth and glossy.
- Finish the Cake: Pour the chocolate ganache over the chilled mousse layer and spread evenly with a spatula. Refrigerate the cake for an additional 30 minutes to allow the ganache to set before slicing and serving.
Notes
- For a richer flavor, use dark chocolate instead of semi-sweet chocolate in the mousse and ganache.
- Chill the mixing bowl before whipping the cream to achieve the best mousse texture and stability.
- This cake can be prepared a day ahead and stored in the refrigerator to enhance flavor and ease of serving.
