Ingredients
For the Cake:
- 3 large eggs, at room temperature
- 1/2 tbsp Clabber Girl Baking Soda
- 1 cup hot water
- 1/2 cup vegetable oil
- 1 cup unsweetened cocoa powder
- 2.5 cups brown sugar or white granulated sugar
- 1/2 tbsp pure vanilla extract
- 2 cups all-purpose flour
- 1 tsp salt
- 1/2 tbsp baking powder
- 1 cup buttermilk or whole milk
- 1 stick butter
For the Chocolate Mousse:
- 7 ounces semisweet chocolate chips
- 1 cup heavy cream or half and half
For the Frosting:
- 3 cups powdered sugar
- 1/2 cup whole milk
- 1 cup unsalted butter, softened
- 1 cup unsweetened cocoa powder
- 1/2 tbsp pure vanilla extract
Instructions
- In a large bowl, combine the eggs, baking soda, hot water, vegetable oil, cocoa powder, sugar, butter and vanilla extract. Whisk until smooth.
- Sift in the flour, salt, and baking powder into the wet ingredients and mix until just combined.
- Pour in the buttermilk and mix until well incorporated.
- Prepare the mousse topping by combining the semisweet chocolate chips and heavy cream in a medium bowl. Microwave for 1 minute or until melted then stir until smooth before allowing to cool slightly.
- Make the frosting by whisking together powdered sugar, vanilla extract and milk in a medium bowl. Add butter and cocoa powder and mix until light and fluffy.
- Preheat oven to 350°F (175°C). Grease two 9-inch round cake pans and line with parchment paper. Divide the batter evenly among the prepared pans and bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Allow to cool completely before frosting.
- Place one layer of cake onto a plate or stand. Spread cooled chocolate mousse evenly over the top and then place a second layer of cake on top. Cover with frosting.
Notes
- Make sure your ingredients are at room temperature before beginning. This will ensure that everything mixes together evenly and prevents lumps from forming in the batter.
- Be sure to grease and line your cake pans before adding the batter. This will help the cakes release easily and prevent them from sticking to the pan.
- Once the cake layers have cooled completely, it’s important to assemble them as soon as possible. If left too long, they can become dry and crumble when you try to frost them.
- When adding the chocolate mousse topping to the cake, use a thin spatula or butter knife to spread it evenly over the top layer of the cake. This will help ensure that the mousse isn’t too thick or thin in any one spot.
- Let the cake chill for at least 30 minutes before serving, as this will help solidify the frosting and keep it from melting off the cake.
