Cake Base Ingredients
- 1 cup all-purpose flour
- 1/2 cup granulated sugar
- 1/2 cup unsalted butter, melted
- 1 teaspoon vanilla extract
Mousse Ingredients
- 200g quality dark chocolate (60–70% cocoa)
- 1 cup heavy cream, chilled
- 3 large eggs, separated (yolks and whites)
- 1/4 cup granulated sugar
- A pinch of salt
- Prepare the Cake Base: Preheat your oven to 350°F (175°C) and grease a cake pan. In a bowl, whisk together the flour, sugar, and melted butter until smooth. Pour the batter into your prepared pan and bake for 20-25 minutes or until the cake is moist and springs back slightly when touched. Once done, remove from oven and allow to cool completely.
- Melt the Chocolate: Place the dark chocolate in a heatproof bowl and gently melt it using a double boiler or microwave in short intervals, stirring frequently to avoid overheating and graininess. Set aside to cool slightly.
- Whip the Cream: Using chilled beaters and bowl, whip the heavy cream until soft peaks form. This gives the mousse its characteristic light and fluffy texture.
- Beat Egg Whites: In a clean bowl, beat the egg whites with a pinch of salt until stiff peaks form. This aerates the mousse, making it light and airy.
- Combine Ingredients: Gently fold the melted chocolate into the whipped cream, mixing carefully to maintain volume. Next, fold in the beaten egg whites carefully to keep the mousse light and airy.
- Assemble the Cake: Spread the chocolate mousse evenly over the cooled cake base using a spatula to smooth the top. Refrigerate the assembled cake for at least 4 hours to allow the mousse to set and the flavors to meld.
Notes
- Use room temperature eggs for better volume when whipping egg whites.
- Gently fold ingredients to keep mousse airy and prevent collapse.
- Chill the heavy cream and mixing bowls for better whipping results.
- Choose high-quality dark chocolate for the best flavor.
- Allow at least 4 hours chilling time to firm the mousse.
