Ingredients

  • For the Chocolate Cake:

    • 2 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 hot brewed coffee

  • For the White Chocolate Mousse:

    • 12 ounces good-quality white chocolate, finely chopped

    • 1 ½ cups heavy cream, divided

    • 1 teaspoon gelatin powder

    • 2 tablespoons cold water

  • For the Chocolate Ganache:

    • 8 ounces good-quality dark chocolate, finely chopped

    • 1 cup heavy cream

Instructions

  1. Prepare the Chocolate Cake: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

  2. In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.

  3. In a separate bowl, combine the buttermilk, oil, eggs, and vanilla extract. Add the wet ingredients to the dry ingredients and mix until just combined.

  4. Gradually pour in the hot coffee while mixing on low speed until the batter is smooth. Be careful to avoid splashing hot coffee.

  5. 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.

  6. Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.

  7. Make the White Chocolate Mousse: In a small bowl, sprinkle the gelatin over cold water and let it bloom for 5 minutes.

  8. In a separate heatproof bowl, place the finely chopped white chocolate.

  9. Heat ½ cup of the heavy cream in a small saucepan until it just begins to simmer. Pour over the white chocolate and let it sit for a minute to allow the chocolate to soften. Whisk until the chocolate is completely melted and smooth.

  10. Heat the bloomed gelatin in the microwave for about 10-15 seconds until melted, and stir it into the white chocolate.

  11. In a separate bowl, whip the remaining 1 cup of heavy cream until stiff peaks form.

  12. Gently fold the whipped cream into the white chocolate mixture until the mousse is light and airy.

  13. Assemble the Cake: Once the cake layers are completely cool, place one layer on a serving plate or cake stand.

  14. Spread the white chocolate mousse evenly over the first cake layer. Top with the second cake layer.

  15. Prepare the Chocolate Ganache: Place the chopped dark chocolate in a heatproof bowl. Heat the heavy cream in a small saucepan until it just begins to simmer. Pour the hot cream over the chocolate.

  16. Let the mixture sit for a minute, then whisk until smooth and glossy.

  17. Pour the ganache over the top of the cake, allowing it to drip down the sides. Use a spatula to gently smooth the ganache over the top and sides.

  18. Refrigerate the cake for at least 2 hours to allow the ganache to set and the mousse to firm up.

  19. Slice and serve.

Notes

  • For a richer flavor, use good-quality dark chocolate and white chocolate.

  • Ensure your cake layers are completely cool before assembling, or else the mousse will melt.

  • If you prefer a less sweet mousse, you can adjust the amount of white chocolate.

  • For a smooth ganache, make sure the cream is just at a simmer (not boiling).

  • You can also add a thin layer of chocolate shavings or white chocolate curls as decoration over the top of the ganache before it sets.

  • For a more intensely flavored chocolate cake, you can use a slightly higher percentage of cocoa powder.
