Equipment

  • 8–9-inch round cake pan
  • Parchment paper
  • Mixing bowls
  • Whisk & spatula
  • Hand mixer (optional)
  • Double boiler or heatproof bowl + saucepan
  • Strainer (for ganache if needed)

Ingredients
  

Cake Base:

  • 1 cup all-purpose flour (or almond flour for gluten-free)
  • ½ cup Dutch-process cocoa powder
  • 1 cup granulated sugar
  • ½ tsp salt
  • 1 tsp espresso powder (optional)
  • 2 large eggs
  • ½ cup melted butter
  • 1 tsp vanilla extract

Truffle/Mousse Layer:

  • 8 oz dark chocolate (60–70%)
  • 1 cup heavy cream (divided)
  • 2 tbsp powdered sugar (optional, for stability)

Ganache Topping:

  • 6 oz dark or semisweet chocolate
  • ½ cup heavy cream
  • 2 tbsp butter

Instructions
 

  • Bake the base: Whisk flour, cocoa, sugar, salt, and espresso powder. In another bowl, combine eggs, butter, and vanilla. Fold wet into dry until smooth. Bake at 350°F (175°C) for 25–30 minutes, until a toothpick shows moist crumbs. Cool completely.
  • Bake the base: Whisk flour, cocoa, sugar, salt, and espresso powder. In another bowl, combine eggs, butter, and vanilla. Fold wet into dry until smooth. Bake at 350°F (175°C) for 25–30 minutes, until a toothpick shows moist crumbs. Cool completely.
  • Prepare ganache: Heat cream until steaming. Pour over chocolate, add butter, whisk until glossy. Pour over set mousse layer, tap pan to smooth. Chill until softly set (30–60 minutes).
  • Serve: Slice slightly chilled for clean edges. Let sit 10 minutes before serving for silkier texture.

Notes

  • Make-ahead: Assemble a day early; flavors bloom overnight.
  • Storage: Refrigerate covered; best within 3–4 days.
  • Freezing: Wrap slices tightly; thaw overnight in fridge.
  • Variations: Try mocha (espresso powder), raspberry (purée folded into mousse), or salted caramel (thin layer under ganache).
  • Tip: Warm knife before slicing for clean edges.
