How to Make Rich Chocolate Mousse Cake
Ingredients:
- 1 1/2 cups all-purpose flour
- 1 cup granulated sugar
- 1/2 cup unsweetened cocoa powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup milk
- 1/4 cup vegetable oil
- 1 large egg
- 1 teaspoon vanilla extract
- 1/2 cup boiling water
- 1 1/2 cups heavy cream
- 8 ounces good quality dark chocolate, chopped
- 2 tablespoons granulated sugar
- 1 teaspoon vanilla extract
- 1/2 cup heavy cream
- 4 ounces good quality dark chocolate, chopped
Directions:
- Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round springform pan.
- For the cake base, in a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt.
- Add the milk, oil, egg, and vanilla extract to the dry ingredients and mix until well combined.
- Carefully stir in the boiling water until the batter is smooth. Pour the batter into the prepared springform pan.
- Bake for 25-30 minutes, or until a wooden toothpick inserted into the center comes out clean.
- Let the cake cool completely in the pan on a wire rack. Once cool, remove the sides of the springform pan.
- For the chocolate mousse, melt the chopped dark chocolate in a heatproof bowl set over a pan of simmering water, stirring until smooth. Remove from heat and let cool slightly.
- In a separate large bowl, beat the heavy cream with granulated sugar and vanilla extract until stiff peaks form.
- Gently fold the cooled melted chocolate into the whipped cream until no streaks remain.
- Pour the chocolate mousse over the cooled cake base in the springform pan, spreading it evenly. Refrigerate for at least 4 hours, or until the mousse is set.
- For the chocolate ganache topping, heat the heavy cream just until it begins to simmer. Remove from heat and add the chopped dark chocolate. Let sit for 5 minutes, then whisk until smooth.
- Pour the slightly cooled ganache over the set chocolate mousse layer, tilting the pan to ensure even coverage. Refrigerate for another 30 minutes to an hour to allow the ganache to set.
