Ingredients
  

For the Cake
  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 1 cup unsweetened cocoa powder
  • 1.5 tsp baking powder
  • 1.5 tsp baking soda
  • 1 tsp salt
  • 2 large eggs
  • 1 cup buttermilk
  • 0.5 cup vegetable oil
  • 2 tsp vanilla extract
  • 1 cup boiling water (or hot coffee for a richer flavor)
For the Mousse
  • 8 oz semi-sweet chocolate, chopped
  • 1 cup heavy cream, divided
  • 2 tbsp powdered sugar
  • 1 tsp vanilla extract
For the Ganache
  • 8 oz semi-sweet chocolate, chopped
  • 0.5 cup heavy cream
  • 1 tbsp unsalted butter
For Garnish
  • Chocolate shavings or curls
  • Fresh berries (optional)
  • Edible gold dust (optional)

Method
 

Preparation
  1. Preheat the oven to 350°F (175°C). Grease, flour, and line two 9-inch round cake pans with parchment paper.
  2. In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  3. Add the eggs, buttermilk, vegetable oil, and vanilla extract. Beat on medium speed until well combined.
  4. Gradually mix in the boiling water or hot coffee until the batter is smooth.
  5. Divide the batter evenly between the prepared pans. Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.
  6. Allow the cakes to cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
Make the Mousse
  1. Melt the chopped chocolate in a double boiler or microwave.
  2. In a separate bowl, whip 1/2 cup of heavy cream with powdered sugar and vanilla extract until stiff peaks form.
  3. Fold the whipped cream into the melted chocolate until fully combined.
Prepare the Ganache
  1. Heat the remaining heavy cream until it simmers.
  2. Pour it over the chopped chocolate and let it sit for a few minutes before stirring until smooth. Add the butter and mix until fully blended.
Assemble the Cake
  1. Optionally, slice each cooled cake horizontally to create four layers.
  2. Place one layer on a serving plate and spread a layer of mousse on top.
  3. Repeat this process with the other layers, ending with mousse on top.
  4. Pour the ganache over the assembled cake, allowing it to drip down the sides.
  5. Garnish with chocolate shavings, fresh berries, or edible gold dust if desired.
  6. Refrigerate the cake for at least 1 hour to allow the mousse to set.

Notes

Make sure all your ingredients are at room temperature for better mixing. Don't overmix the batter after adding the boiling water or coffee. Allow the cake layers to cool completely before assembling to avoid melting the mousse. Chill the ganache slightly before pouring to help it maintain its shape on the cake.
