- 1 teaspoon vanilla extract
- 65 g plain flour (all-purpose)
- 15 g cocoa powder
- 1 teaspoon baking powder
- ½ teaspoon espresso powder
- ¼ teaspoon salt
- 75 g dark chocolate 75%, melted
Raspberry Mousse
- 2¼ teaspoon powdered gelatine
- 45 ml fresh lemon juice
- 400 g fresh raspberries (frozen can be substituted)
- 100 g granulated sugar
- 480 ml double cream (heavy cream), cold

- 125 g fresh raspberries
- 50 g dark chocolate shavings
Instructions
- Prepare Chocolate Sponge: Grease and line the base and sides of a 23cm (9-inch) springform pan. Preheat oven to 180°C (350°F).
- Whip Eggs & Sugar: In a medium bowl, combine eggs, light brown sugar, granulated sugar, and vanilla extract. Using a hand mixer, whip on medium-high speed for about 4 minutes until light, creamy, and ribbons form when the whisk is lifted.
- Add Dry Ingredients: Sift in flour, cocoa powder, baking powder, espresso powder, and salt. Mix on low speed until only a few streaks of flour remain.
- Incorporate Melted Chocolate: Carefully fold the melted dark chocolate into the batter using a rubber spatula, scraping the bowl to ensure a smooth mixture.
- Bake Sponge: Pour the batter into the prepared pan, tap to release air bubbles, and smooth the surface with an offset spatula if needed. Bake for 15-20 minutes until the center springs back to the touch.
- Cool and Flatten Sponge: Cool the sponge on a wire rack to room temperature. Press the wrinkly top flat using a flat glass or the base of a measuring cup. Cover and refrigerate until needed.
- Bloom Gelatine: Mix lemon juice with powdered gelatine in a small bowl. Let sit for a few minutes to soften.
- Blend Raspberries: Puree fresh raspberries in a blender until smooth.
- Strain Raspberry Puree: Pass the puree through a fine sieve over a saucepan to discard seeds, yield approximately 300 ml of smooth pulp.
- Heat Raspberry Puree: Place the puree on medium-low heat, add granulated sugar, and simmer while stirring frequently.
- Dissolve Gelatine: Stir softened gelatine into the hot puree and heat gently without boiling until completely dissolved.
- Strain Again & Cool: Strain the puree again to remove any lumps. Set aside to cool to room temperature (about 20 minutes).
- Whip Cream & Combine: Whip the cold double cream to soft peaks. Gently fold in the cooled raspberry puree in three parts to maintain the airy texture.
- Assemble Mousse Cake: Pour the 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, preferably overnight, to set.
- Decorate & Serve: Remove the cake from the pan, peel off the baking paper collar, and smooth edges if needed with a warm spatula. Decorate with fresh raspberries and dark chocolate shavings. Slice with a warm sharp knife and serve immediately.
Notes
- Use room temperature eggs for better batter aeration and volume.
- Blooming gelatine ensures a smooth mousse texture without lumps.
- Using an offset spatula helps to smooth batter and mousse layers evenly.
- Refrigerate the cake at least 3 hours to fully set the mousse; overnight is best for flavor development.
- If fresh raspberries are unavailable, frozen ones can be substituted but thaw and drain excess moisture before use.
- Warm the knife blade under hot water and wipe dry before slicing the cake for clean cuts.
