Ingredients

  • 150 g dark chocolate
  • 100 g unsalted butter
  • 150 g granulated sugar (¾ cup)
  • 2 large eggs
  • 95 g all-purpose flour (¾ cup)
  • 2 tablespoons unsweetened cocoa powder
  • 200 g cream cheese, softened
  • 120 g peanut butter (½ cup)
  • 60 g powdered sugar (½ cup)
  • 240 ml heavy cream (1 cup), cold
  • 150 g dark chocolate (for chocolate mousse)
  • 240 ml heavy cream (1 cup), cold (for chocolate mousse)
  • 240 ml heavy cream (1 cup), cold (for cocoa topping)
  • 2 tablespoons powdered sugar (for cocoa topping)
  • 2 tablespoons unsweetened cocoa powder (for cocoa topping)

Instructions

  1. Preheat oven to 340°F (170°C). Grease and line an 8-inch round cake pan.
  2. Melt chocolate and butter together until smooth. Stir in sugar, then add eggs one at a time. Mix well.
  3. Fold in flour and cocoa powder until just combined. Pour into pan and bake for 20 minutes. Let cool completely in pan.
  4. For peanut butter mousse: beat cream cheese until smooth. Add peanut butter and powdered sugar, mix until creamy. Whip heavy cream to soft peaks and fold into the peanut butter mixture.
  5. For chocolate mousse: melt chocolate and let cool slightly. Whip cream to soft peaks and fold into melted chocolate until smooth.
  6. For cocoa cream topping: whip heavy cream with powdered sugar and cocoa powder until medium peaks form.
  7. Assemble the cake: spread peanut butter mousse over cooled brownie layer. Add chocolate mousse on top, then finish with cocoa cream topping.
  8. Refrigerate for at least 4 hours or until fully set. Slice and serve chilled.

Notes

  • Use almond butter instead of peanut butter for a different flavor.
  • Add a thin layer of ganache between mousse layers for richness.
  • Top with chopped nuts or chocolate curls for texture.
  • Chill overnight for best results.
  • Clean knife between slices for neat presentation.
