Chocolate Sponge
- 3 large eggs (room temperature)
- 55 g light brown sugar
- 65 g granulated sugar
- 1 tsp vanilla extract
- 65 g plain flour (all-purpose)
- 15 g cocoa powder
- 1 tsp baking powder
- ½ tsp espresso powder
- ¼ tsp salt
- 75 g Dark Chocolate 75% (melted)
Raspberry Mousse
- 2¼ tsp powdered gelatine
- 45 ml fresh lemon juice
- 400 g fresh raspberries (or frozen as substitute)
- 100 g granulated sugar
- 480 ml double cream (heavy cream) (cold)
Decoration
- 125 g fresh raspberries
- 50 g Dark Chocolate shavings
- Prepare pan and preheat oven: Grease and line the base and sides of a 23cm (9-inch) springform pan. Preheat oven to 180°C (350°F).
- Whip eggs and sugars: In a medium bowl, combine eggs, light brown sugar, granulated sugar, and vanilla extract. Using an electric whisk, beat on medium-high speed for about 4 minutes until the mixture is light, creamy, and ribbons form when the whisk is lifted.
- Incorporate dry ingredients: Sift flour, cocoa powder, baking powder, espresso powder, and salt into the egg mixture. Mix on low speed until mostly combined with only a few flour streaks remaining.
- Add melted chocolate: Fold the melted dark chocolate gently into the batter using a rubber spatula, scraping the bowl to ensure thorough mixing.
- Bake the sponge: Pour batter into the prepared pan and tap to release air bubbles. Smooth the surface with an offset spatula. Bake for 15-20 minutes until the center springs back. Cool on wire rack. Press the top gently with a flat object to flatten, then refrigerate.
- Bloom gelatine: Sprinkle powdered gelatine over lemon juice in a small bowl and mix. Let bloom for a few minutes until softened.
- Prepare raspberry puree: Blend 400 g raspberries until smooth. Pass through a fine sieve to remove seeds, collecting about 300 ml puree.
- Cook raspberry puree with sugar and gelatine: Heat puree and granulated sugar over medium-low heat, stirring until sugar dissolves and simmering gently. Add gelatine mixture and stir until completely dissolved without boiling. Strain again if necessary and cool to room temperature (~20 minutes).
- Whip cream and combine: Whip cold double cream to soft peaks. Fold the cooled raspberry puree into the whipped cream in three parts until fully incorporated.
- Assemble mousse layer: Pour raspberry mousse over the chilled chocolate sponge in the springform pan. Smooth the surface with an offset spatula. Cover and refrigerate for at least 3 hours or overnight to set.
- Decorate and serve: Remove cake from pan, peel off baking paper collar, and smooth edges with a warmed spatula if needed. Transfer to serving plate and garnish with fresh raspberries and dark chocolate shavings. Slice with a warm dry knife and serve immediately.
Notes
- Frozen raspberries can be used instead of fresh for the mousse; thaw fully before blending.
- Pressing the sponge cake ensures a flat surface, improving mousse layering and presentation.
- Use a warm knife when slicing to create clean cake slices.
- Make sure not to boil the gelatine mixture to prevent it from losing its setting properties.
- The mousse benefits from chilling overnight for best texture and flavor melding.
