Ingredients
Scale
Chocolate Base
- 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 teaspoon vanilla extract
- A pinch of salt
Garnish (Optional)
- Whipped cream
- Cocoa powder, for dusting
- Fresh berries (raspberries or strawberries)
Instructions
- Preheat and Prepare Pan: 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: Using a double boiler setup, melt the chopped dark chocolate and cubed butter together, stirring occasionally until smooth. Stir in the instant coffee granules if using, then remove from heat and allow the mixture to cool slightly.
- Whisk Egg Yolks and Sugar: In a large bowl, whisk the egg yolks with 1/2 cup (100 g) of granulated sugar until the mixture becomes pale and thick. Add vanilla extract and mix well.
- Combine Chocolate and Egg Yolks: Slowly fold the melted chocolate mixture into the egg yolk mixture until fully blended and smooth.
- Beat Egg Whites: In a separate, clean mixing bowl, beat the egg whites with a pinch of salt until soft peaks form. Gradually add the remaining 1/4 cup (50 g) of sugar and continue beating until stiff, 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. Fold carefully to preserve the airiness without deflating the mixture.
- Transfer and Smooth Batter: Pour the final batter into the prepared springform pan and smooth the top with a spatula.
- Bake the Cake: Bake for 25-30 minutes until the edges are set but the center remains slightly soft. The cake will firm up further as it cools.
- Cool the Cake: Let the cake cool in the pan for 15 minutes. Then, remove the sides of the springform pan and transfer the cake to a wire rack to cool completely.
- Decorate and Serve: Dust the cooled cake with cocoa powder. Serve with a dollop of whipped cream and fresh berries for an elegant finish.
Notes
- Using the instant coffee granules is optional but enhances the depth of the chocolate flavor.
- Ensure the egg whites are beaten to stiff peaks to achieve the light mousse texture.
- Be gentle when folding egg whites to maintain airiness.
- This cake can be prepared a day in advance and stored in the refrigerator.
- To avoid cracks, do not overbake; the center should still be slightly soft when you take it out of the oven.
