- 1 cup granulated sugar
- ½ cup unsweetened cocoa powder
- 1½ teaspoons baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- 2 large eggs
- ¾ cup whole milk
- ½ cup vegetable oil
- 2 teaspoons vanilla extract
- ¾ cup hot coffee
the Chocolate Mousse Layer:
- 12 ounces high-quality dark chocolate, chopped
- 4 large eggs, separated
- 2 cups heavy whipping cream
- ¼ cup granulated sugar
- 1 teaspoon vanilla extract
- Pinch of salt
Decoration:
- 1 cup heavy whipping cream
- 2 tablespoons powdered sugar
- Chocolate shavings
- Fresh berries (optional)
Instructions
Preparing the Chocolate Cake Base
- Preheat your oven to 350°F (175°C). Grease a 9-inch springform pan and line the bottom with parchment paper.
- In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- In a separate bowl, combine eggs, milk, oil, and vanilla extract. Mix well.
- Gradually add the wet ingredients to the dry ingredients, whisking until just combined.
- Stir in the hot coffee until the batter is smooth. The batter will be thin.
- Pour into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
- Cool completely in the pan on a wire rack.
Creating the Chocolate Mousse
- Melt the chocolate in a double boiler or microwave in 30-second intervals, stirring between each interval. Let cool slightly.
- In a clean bowl, beat egg whites with a pinch of salt until soft peaks form. Gradually add ¼ cup sugar and continue beating until stiff peaks form.
- In another bowl, whip 2 cups of heavy cream with vanilla extract until stiff peaks form.
- Stir egg yolks into the melted chocolate until well combined.
- Gently fold one-third of the whipped cream into the chocolate mixture to lighten it.
- Fold in the remaining whipped cream until just combined.
- Finally, fold in the egg whites carefully to maintain the airy texture.
Assembly and Decoration
- Once the cake is completely cool, run a knife around the edge and remove the springform ring.
- Clean and reassemble the springform pan around the cake.
- Pour the mousse mixture over the cake base, smoothing the top with a spatula.
- Refrigerate for at least 6 hours or overnight until the mousse is set.
- Before serving, whip 1 cup of cream with powdered sugar until stiff peaks form.
- Remove the springform ring and decorate the cake with whipped cream, chocolate shavings, and fresh berries if desired.
Storage Instructions
Store the mousse cake in the refrigerator, covered, for up to 3 days. While freezing is possible, it may affect the texture of the mousse, so it's best enjoyed fresh.

FAQ
What is the difference between a mousse cake and a regular cake?
A mousse cake combines layers of traditional cake with light, airy mousse layers, while a regular cake consists only of baked cake layers with frosting. Mousse cakes require refrigeration to maintain their structure as they contain whipped cream, eggs, and gelatin. The texture is significantly lighter and creamier than traditional cakes, with the mousse providing a silky, smooth contrast to the cake layers.
What are common mistakes when making mousse?
Common mousse-making mistakes include: overwhipping the cream (causing graininess), not tempering eggs properly (causing scrambling), folding too vigorously (deflating the mixture), not allowing enough chilling time, and using warm ingredients. Another crucial error is not properly blooming gelatin or using incorrect gelatin amounts, which affects the final texture. Temperature control throughout the process is essential.
Does a chocolate mousse cake need to be refrigerated?
Yes, chocolate mousse cake must be refrigerated due to its dairy content and delicate structure. It should be stored at 40°F (4°C) or below and can last 3-5 days when properly refrigerated. The mousse layers contain perishable ingredients like cream, eggs, and chocolate, making refrigeration essential for both food safety and maintaining the proper texture.
What are the three basic elements of a mousse?
The three basic elements of mousse are: the base (chocolate, fruit puree, or flavoring), the aerator (whipped cream or beaten egg whites), and the binder (gelatin, egg yolks, or chocolate). These components work together to create the signature light and airy texture. The proper balance and incorporation of these elements determine the mousse's final structure and stability.
