Ingredients
Scale
Chocolate Mixture
- 10 oz (300 g) dark chocolate, chopped
- 5 oz (150 g) unsalted butter, cubed
- 1 teaspoon instant coffee granules (optional)
Egg Mixture
- 4 large eggs, separated
- 3/4 cup (150 g) granulated sugar (divided: 1/2 cup (100 g) and 1/4 cup (50 g))
- 1 teaspoon vanilla extract
- A pinch of salt
For Serving (Optional)
- Whipped cream
- Cocoa powder, for dusting
- Fresh berries (raspberries or strawberries)
Instructions
- Preheat the oven: Preheat your oven to 350°F (175°C). Grease an 8-inch (20 cm) springform cake pan and line the base with parchment paper to prevent sticking.
- Melt chocolate and butter: Set a heatproof bowl over a pot of simmering water to create a double boiler. Melt the chopped dark chocolate and cubed unsalted butter together, stirring occasionally until smooth. Add the instant coffee granules if using, then remove from heat and let cool slightly.
- Prepare egg yolk mixture: In a large mixing bowl, whisk the egg yolks with 1/2 cup (100 g) of granulated sugar until the mixture becomes pale and thick. Stir in the vanilla extract for flavor.
- Combine chocolate and yolks: Gradually fold the cooled melted chocolate mixture into the egg yolk mixture, blending gently until smooth and fully combined.
- Beat egg whites: In a clean bowl, beat the egg whites with a pinch of salt until soft peaks form. Gradually add the remaining 1/4 cup (50 g) granulated sugar and continue beating until stiff, glossy peaks form, indicating a stable meringue.
- Fold in egg whites: Carefully fold the beaten egg whites into the chocolate mixture in three portions, using a spatula. Work gently to maintain the light and airy texture, folding until just combined without deflating the batter.
- Pour and smooth batter: Pour the batter into the prepared springform pan and spread the top evenly to ensure uniform baking.
- Bake the cake: Bake in the preheated oven for 25-30 minutes. The cake should be set around the edges but remain slightly soft in the center. It will firm up as it cools.
- Cool the cake: Allow the cake to cool in the pan for about 15 minutes. Remove the springform sides and transfer the cake to a wire rack to cool completely.
- Serve: Dust the top lightly with cocoa powder and serve accompanied by whipped cream and fresh berries if desired for an elegant touch.
Notes
- Using a double boiler to melt chocolate ensures smoothness and prevents burning.
- Be gentle when folding the egg whites to keep the mousse light and airy.
- Instant coffee granules are optional but enhance the chocolate flavor significantly.
- A springform pan makes removing the delicate mousse cake easier without damaging its edges.
