Ingredients
Scale
Chocolate Sponge Cake
- 3 large eggs, room temperature
- 55 g light brown sugar
- 65 g granulated sugar
- 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 teaspoons 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
Decoration
- 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 the 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 the mixture is light and creamy and ribbons form when the whisk is lifted.
- Add Dry Ingredients: Sift in the plain flour, cocoa powder, baking powder, espresso powder, and salt. Mix on low speed until only a few streaks of flour remain to avoid overmixing.
- Incorporate Melted Chocolate: Carefully fold the melted dark chocolate into the batter using a rubber spatula, scraping the bowl to ensure a smooth and even mixture.
- Bake Sponge: Pour the batter into the prepared pan, tap to release any air bubbles, and smooth the surface with an offset spatula if needed. Bake for 15-20 minutes or until the center springs back when lightly pressed.
- Cool and Flatten Sponge: Allow the sponge to cool completely on a wire rack. Press the wrinkly top flat using the base of a flat glass or measuring cup. Cover and refrigerate until needed.
- Bloom Gelatine: In a small bowl, mix the fresh lemon juice with the powdered gelatine. Let it sit for a few minutes to soften and bloom.
- Blend Raspberries: Puree the fresh raspberries in a blender until smooth.
- Strain Raspberry Puree: Pass the puree through a fine sieve over a saucepan, discarding the seeds. You should have about 300 ml of smooth pulp.
- Heat Raspberry Puree: Place the puree on medium-low heat, add granulated sugar, and simmer while stirring frequently until sugar dissolves.
- Dissolve Gelatine: Stir the softened gelatine into the hot raspberry puree and heat gently without boiling until completely dissolved.
- Strain Again & Cool: Strain the puree again to remove any lumps and set aside to cool to room temperature (approximately 20 minutes).
- Whip Cream & Combine: Whip the cold double cream to soft peaks. Gently fold the cooled raspberry puree into the whipped cream in three additions to keep the mousse airy and light.
- Assemble Mousse Cake: Pour the 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, preferably overnight, to allow the mousse to set fully.
- Decorate & Serve: Remove the cake from the pan, peel off the baking paper collar, and smooth the edges if necessary using a warm spatula. Decorate the top of the cake with fresh raspberries and dark chocolate shavings. Slice with a warm, sharp knife and serve immediately.
Notes
- Use room temperature eggs to achieve better volume when whipping.
- If fresh raspberries are not available, frozen raspberries can be used but should be thoroughly thawed and drained.
- Pressing the sponge flat after cooling ensures an even base for the mousse layer.
- Use a warm knife for cleaner slices when serving the mousse cake.
- For best results, let the mousse set overnight for a firmer texture and enhanced flavor.
