Ingredients
- Base & Layer: * 2 thin layers of rich chocolate sponge cake
- Mousse Filling:
- 1 ½ cups heavy cream, whipped
- 1 cup mascarpone cheese, softened
- ½ cup powdered sugar
- 3 tbsp high-quality cocoa powder
- 1 shot of espresso (cooled) or 1 tsp instant coffee dissolved in water
- Topping & Garnish:
- ½ cup dark chocolate ganache (melted chocolate + heavy cream)
- Chocolate sprinkles or flakes for the sides
- Extra whipped cream for piping
- Cocoa powder for dusting
- Chocolate curls or shavings
Step-by-Step Instructions
- Prepare the Base: Place the first layer of chocolate sponge at the bottom of a lined loaf pan.
- The Tiramisu Mousse: Beat the mascarpone, powdered sugar, cocoa powder, and espresso until smooth. Gently fold in the whipped heavy cream until airy and uniform.
- Assemble the Layers: Spread half of the mousse over the base sponge. Top with the second layer of sponge, then add the remaining mousse. Smooth the top and freeze for 4 hours to set.
- The Ganache Finish: Pour the smooth chocolate ganache over the top of the chilled cake, allowing it to slightly drip down the sides.
- Side Coating: Carefully remove the cake from the mold and press chocolate sprinkles or flakes into the sides for a textured finish.
- Decorative Piping: Pipe dual-toned or alternating chocolate and vanilla cream rosettes down the length of the cake.
- Final Flourish: Dust the top generously with cocoa powder and garnish each rosette with a delicate chocolate curl.
- Thaw & Serve: Refrigerate for 1 hour before serving to ensure the perfect mousse consistency.
Pro-Tips for a Professional Look
- Perfect Curls: Use a vegetable peeler on a room-temperature block of dark chocolate to achieve the long, elegant curls seen in the image.
- Sharp Layers: Slicing the cake while it is still very cold or semi-frozen ensures the mousse and sponge layers stay perfectly distinct.
- Coffee Soak: For a more traditional tiramisu flavor, lightly brush the chocolate sponge layers with extra espresso before adding the mousse.
