Ingredients:

For the Chocolate Cake:

• 1 ½ cups all-purpose flour
• 2 cups granulated sugar
• ¾ cup unsweetened cocoa powder
• 1 ½ teaspoons baking powder
• 1 ½ teaspoons baking soda
• 1 teaspoon salt
• 1 cup buttermilk
• ½ cup vegetable oil
• 2 large eggs
• 2 teaspoons vanilla extract
• 1 cup boiling water

For the Chocolate Mousse:

• 1 cup heavy cream, chilled
• 1 cup semi-sweet chocolate chips
• ¼ cup granulated sugar
• 1 teaspoon vanilla extract

For the Ganache (Optional):

• ½ cup heavy cream
• 4 ounces semi-sweet chocolate, finely chopped

Instructions:

Making the Chocolate Cake:

1. Preheat & Prep: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. Dry Ingredients: In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.
3. Wet Ingredients: In a separate bowl, combine buttermilk, oil, eggs, and vanilla extract.
4. Combine: Gradually add the wet ingredients to the dry ingredients, mixing until just combined.
5. Boiling Water: Slowly pour in the boiling water while mixing on low speed. The batter will be thin.
6. Bake: Divide the batter evenly between the prepared cake pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
7. Cool: Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.

Making the Chocolate Mousse:

1. Melt Chocolate: Melt the chocolate chips in a double boiler or in the microwave in 30-second intervals, stirring until smooth. Let cool slightly.
2. Whip Cream: In a chilled bowl, beat the heavy cream with an electric mixer until stiff peaks form.
3. Fold: Gently fold in the melted chocolate, sugar, and vanilla extract into the whipped cream until combined. Be careful not to overmix.

Assembling the Gateau:

1. Level Cakes (Optional): If your cake layers are uneven, use a serrated knife to level them.
2. Layer: Place one cake layer on a serving plate or cake stand. Spread half of the chocolate mousse evenly over the cake layer. Top with the second cake layer.
3. Frost: Frost the entire cake with the remaining chocolate mousse.
4. Ganache (Optional): If using, melt the chocolate and heavy cream together. Let it cool slightly before drizzling over the mousse.
5. Chill: Refrigerate the gateau for at least 4 hours, or preferably overnight, to allow the mousse to set.

Tips for Success:

• Room Temperature Ingredients: Ensure your eggs and buttermilk are at room temperature for optimal mixing.
• Don't Overmix: Overmixing the cake batter can lead to a tough cake. Mix until just combined.
• Chill Time is Key: Allow sufficient chilling time for the mousse to set properly. The longer it chills, the firmer it will become.
• Get Creative with Decorations: Garnish with fresh berries, chocolate shavings, or even a dusting of cocoa powder for an extra touch of elegance.

This chocolate mousse gateau recipe is sure to become a favorite! Its rich chocolate flavor and airy texture make it a truly unforgettable dessert. Enjoy!
