Ingredients

Scale

For the Cake

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

For the Mousse

  • 8 oz semisweet chocolate
  • 2 cups heavy whipping cream
  • ¼ cup granulated sugar
  • 1 teaspoon vanilla extract

For the Ganache

  • ½ cup heavy whipping cream
  • 4 oz bittersweet chocolate, chopped
  • 1 tablespoon light corn syrup
  • 1 tablespoon unsalted butter

Instructions

  1. Preheat Oven and Prepare Pans: Preheat your oven to 350°F (175°C) and grease or line two round cake pans to prevent sticking.
  2. Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt until evenly combined.
  3. Mix Wet Ingredients: In a separate bowl, beat the eggs, vegetable oil, buttermilk, and hot coffee together until smooth.
  4. Combine Ingredients: Gradually add the wet mixture into the dry ingredients and stir just until everything is combined. Avoid overmixing to keep the cake tender.
  5. Bake the Cake: Pour the batter evenly into the prepared cake pans. Bake for 25–30 minutes or until a toothpick inserted into the center comes out clean. Allow the cakes to cool completely before proceeding.
  6. Prepare the Chocolate Mousse: Melt the semisweet chocolate and let it cool slightly. In a chilled bowl, whip the heavy whipping cream with sugar and vanilla extract until stiff peaks form. Gently fold the melted chocolate into the whipped cream to create a smooth mousse.
  7. Assemble the Cake: Using a springform pan, layer one cake layer followed by a thick layer of chocolate mousse. Repeat with the second layer and mousse. Refrigerate until the mousse is set, about 2 hours.
  8. Make the Ganache: Heat the remaining heavy cream until just boiling, then pour it over the chopped bittersweet chocolate. Let it sit for a few minutes, then stir until smooth. Add corn syrup and butter, stirring until glossy.
  9. Finish the Cake: Remove the mousse cake from the refrigerator and spread the ganache evenly over the top. Return to the fridge briefly if needed to set the ganache before serving.

Notes

  • Use high-quality chocolate for the best mousse and ganache flavor.
  • Ensure the cake layers are completely cooled before adding the mousse to prevent melting.
  • For easier mousse folding, gently incorporate melted chocolate using a rubber spatula to maintain airiness.
  • Store leftover cake covered in the refrigerator for up to 3 days.
  • The cake can be made one day ahead and refrigerated to enhance flavors.
