Ingredients
Scale
Main Ingredients
- 10 oz (300 g) dark chocolate, chopped
- 5 oz (150 g) unsalted butter, cubed
- 1 teaspoon instant coffee granules (optional)
- 4 large eggs, separated
- 3/4 cup (150 g) granulated sugar
- 1 teaspoon vanilla extract
- A pinch of salt
For Serving (Optional)
- Whipped cream
- Cocoa powder, for dusting
- Fresh berries (raspberries or strawberries)
Instructions
- Preheat and Prepare Pan: Preheat the 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: Using a double boiler setup with a heatproof bowl over simmering water, melt the chopped dark chocolate and cubed butter together, stirring occasionally until smooth. Add 1 teaspoon instant coffee granules for an enhanced flavor depth if desired. Remove from heat and let cool slightly.
- Whisk Egg Yolks and Sugar: In a large bowl, whisk the 4 egg yolks with 1/2 cup (100 g) of the granulated sugar until the mixture is pale, thick, and creamy. Then stir in the vanilla extract for aroma.
- Combine Chocolate Mixture with Yolks: Gradually fold the melted chocolate and butter blend into the egg yolk mixture, stirring gently until smooth and well integrated.
- Beat Egg Whites: In a separate clean bowl, beat the 4 egg whites with a pinch of salt until soft peaks form. Gradually add the remaining 1/4 cup (50 g) sugar while continuing to whisk until stiff and glossy peaks develop.
- Fold Egg Whites into Chocolate Mixture: Gently fold the beaten egg whites into the chocolate mixture in three parts using a spatula. Be careful to fold gently to retain the airiness and avoid deflating the batter.
- Pour Batter into Pan: Transfer the mousse batter into the prepared springform pan and smooth the top with a spatula for an even surface.
- Bake the Cake: Bake in the preheated oven for 25-30 minutes, until the edges are set but the center remains slightly soft. The cake will firm up as it cools.
- Cool the Cake: Allow the cake to cool in the pan for 15 minutes. Then carefully remove the sides of the springform pan and transfer the cake onto a wire rack to cool completely.
- Serve and Garnish: Dust the top of the cooled cake with cocoa powder. Serve with a dollop of whipped cream and fresh berries such as raspberries or strawberries for a delightful presentation and added freshness.
Notes
- For best results, use high-quality dark chocolate with at least 60-70% cocoa content.
- The instant coffee granules are optional but add a subtle depth that enhances the chocolate flavor.
- Be gentle when folding in the egg whites to maintain a light and airy texture.
- The cake is slightly underbaked in the center when removed from the oven to preserve the mousse-like consistency.
- Store leftovers in the refrigerator and consume within 2-3 days for optimal freshness.
