You’ll find ingredients that bring an authentic flavor to every bite.
This Chocolate Mousse Cake Recipe proves that authentic flavor comes from thoughtful ingredient choices. The buttermilk adds a subtle tang to the cake, while the semi-sweet chocolate provides a deep, rich flavor to the mousse. Make sure your eggs are fresh; they’re essential for creating that perfect, airy texture in the mousse.
My family loves when I add a touch of espresso powder to the cake batter. It intensifies the chocolate flavor and adds a subtle depth that everyone raves about.

Let’s Create This Together!
Follow these step-by-step instructions to create your very own delicious Chocolate Mousse Cake Recipe:
- Prepare the Chocolate Cake:
Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan. In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. In a separate bowl, combine the sugar, buttermilk, oil, eggs, and vanilla extract. Add the wet ingredients to the dry ingredients and mix until just combined. Gradually add the boiling water and stir until the batter is smooth. Pour the batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. In my kitchen, this flavorful Chocolate Mousse Cake Recipe typically takes about 32 minutes to bake perfectly.
- Cool the Cake:
Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely. This step is crucial to prevent the cake from sticking and to ensure it maintains its shape. Perfect time to appreciate the aromatic transformation!
- Prepare the Chocolate Mousse:
In a heatproof bowl set over a pot of simmering water (double boiler), melt the chopped chocolate. Stir occasionally until smooth. Remove from heat and let it cool slightly.
- Separate the Eggs:
In a large bowl, beat the egg yolks with the sugar until pale and thick. Stir in the vanilla extract and the cooled melted chocolate. This mixture should be silky and luscious.
- Whip the Cream:
In a separate bowl, whip 1 cup of the heavy cream until stiff peaks form. Gently fold the whipped cream into the chocolate mixture. This step is where the mousse begins to take shape, becoming light and airy.
- Beat the Egg Whites:
In another clean bowl, beat the egg whites until stiff peaks form. Gently fold the egg whites into the chocolate mixture. This adds even more airiness to the mousse, creating that signature light texture.
- Assemble the Cake:
Once the cake is completely cool, slice it horizontally into two layers. Place one layer on a serving plate. Spread the chocolate mousse evenly over the first layer of cake. Place the second layer on top of the mousse.
- Chill the Cake:
Whip the remaining 1/2 cup of heavy cream until soft peaks form. Frost the top of the cake with the whipped cream. Refrigerate the Chocolate Mousse Cake Recipe for at least 2 hours to allow the mousse to set. Your Chocolate Mousse Cake Recipe should fill the kitchen with amazing aromas by now.
- Garnish and Serve:
Before serving, garnish with chocolate shavings and fresh berries, if desired. Slice and enjoy this incredibly rich and satisfying dessert. Don’t be surprised if your Chocolate Mousse Cake Recipe develops a devoted following among your family and friends.
Here’s where I used to miss a key step with my Chocolate Mousse Cake Recipe – learn from my experience! Make sure to let the melted chocolate cool slightly before adding it to the egg yolks to prevent them from cooking. While your Chocolate Mousse Cake Recipe is developing these flavors, take a moment to appreciate creating something special for your family!
