Dark Chocolate Mousse Cake Recipe Details
Prep Time: 25 minutes | Cook Time: 30 minutes | Total Time: 4 hours 55 minutes (includes chilling) | Servings: 8 slices
Ingredients
- 200 g dark chocolate (70% cocoa), chopped
- 12 cup unsalted butter
- 4 large eggs, separated
- 12 cup granulated sugar
- 1 cup heavy cream, cold
- 1 teaspoon vanilla extract
- 14 teaspoon salt
- Cocoa powder for dusting
Step-by-Step Instructions
- Preheat oven to 350°F (175°C). Line the bottom of a 9-inch springform pan with parchment paper.
- Melt the dark chocolate and butter together using a double boiler or microwave in short intervals, stirring until smooth. Let cool slightly.
- In a mixing bowl, whisk egg yolks with half of the sugar until pale and creamy. Stir in vanilla extract.
- Gradually mix the melted chocolate mixture into the egg yolk mixture until fully combined.
- In a separate bowl, beat egg whites with salt until soft peaks form. Slowly add the remaining sugar and continue beating until stiff, glossy peaks form.
- In another bowl, whip the cold heavy cream until soft peaks form.
- Gently fold the whipped cream into the chocolate mixture, then carefully fold in the beaten egg whites in two additions, keeping the mixture light and airy.
- Pour the mousse batter into the prepared pan and smooth the top.
- Bake for 25–30 minutes, until the edges are set but the center is slightly soft.
- Remove from oven and let cool completely, then refrigerate for at least 4 hours or overnight for best texture.
- Before serving, dust lightly with cocoa powder and slice gently.

- Ensure all bowls and beaters are clean and dry before whipping egg whites or cream.
- Fold ingredients gently to maintain the airy texture.

- Add a hint of espresso powder (½ teaspoon) to enhance chocolate flavor.
- Top with fresh berries for a tart contrast.
