Ingredients

Scale

Cake

  • 7 oz dark chocolate (70% cocoa)
  • 1/2 cup unsalted butter
  • 3/4 cup granulated sugar
  • 4 large eggs
  • 1 cup all-purpose flour
  • 1/3 cup unsweetened cocoa powder

Mousse

  • 1 cup heavy cream
  • Remaining melted dark chocolate from cake preparation

Instructions

  1. Preheat and Prepare Pans: Preheat your oven to 350°F (175°C) and grease two round cake pans to ensure the cakes do not stick during baking.
  2. Melt Chocolate and Butter: Melt the dark chocolate and unsalted butter together using a double boiler until the mixture is smooth and completely combined.
  3. Whisk Sugar and Eggs: In a separate bowl, whisk the granulated sugar and eggs until the mixture is pale and fluffy, helping to incorporate air for a lighter texture.
  4. Combine Mixtures: Gently fold the melted chocolate and butter mixture into the sugar and eggs mixture, combining them carefully to maintain airiness.
  5. Add Dry Ingredients: Sift the all-purpose flour and unsweetened cocoa powder into the wet ingredients and fold gently until just combined, avoiding overmixing.
  6. Bake the Cake: Divide the batter evenly between the prepared pans and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Allow cakes to cool completely on a wire rack.
  7. Prepare the Mousse: Whip the heavy cream to stiff peaks, then gently fold it into the remaining melted dark chocolate to create a smooth, airy mousse.
  8. Assemble the Cake: Place one cake layer on a serving plate, spread half of the mousse evenly over it. Top with the second cake layer and finish by spreading the remaining mousse on top. Refrigerate the assembled cake for at least two hours to set before serving.

Notes

  • Use high-quality dark chocolate (at least 70% cocoa) for the best flavor and texture.
  • Ensure cake layers are fully cooled before adding the mousse to prevent melting.
  • For a firmer mousse layer, refrigerate the mousse mixture slightly before folding in whipped cream.
  • This cake is best served chilled and can be stored in the refrigerator for up to 3 days.
