Ingredients for Chocolate Mousse Cake
For the Chocolate Sponge:
To create the base for your chocolate mousse cake, you’ll start with a genoise sponge. This classic cake base is light and airy, making it the perfect complement to the rich mousse.
- 2 large eggs: The eggs provide structure and lift to the cake.
- 55g granulated sugar (¼ cup): Sugar adds sweetness and helps the cake achieve a light, fluffy texture.
- 40g all-purpose flour (⅓ cup): The flour is what gives the sponge its body.
- 10g cocoa powder (1.5 tbsp): Use a high-quality cocoa powder for the best flavor.
- ⅛ tsp salt: Salt enhances the chocolate flavor and balances the sweetness.
- ¼ tsp baking powder: Helps the cake rise and become light.
For the Chocolate Ganache:
The ganache serves as the base for the mousse, providing a rich, smooth, and velvety texture.
- 300g milk chocolate (chopped): You can substitute with dark chocolate if you prefer a less sweet cake.
- 360g heavy cream (1.5 cups): Cream helps to thin out the ganache, making it smooth and easy to work with.
For the Chocolate Mousse:
This mousse is light, airy, and perfect for layering. It complements the rich ganache and chocolate sponge beautifully.
- Ganache from above: You’ll use the ganache you prepared earlier as the base for the mousse.
- 240g heavy cream (1 cup), chilled: The chilled cream will be whipped to add air and lightness to the mousse.
For Decoration (Optional):
- Whipped cream: Whip together ¾ cup heavy cream and 1 tbsp granulated sugar to top the cake.
- Cocoa powder: Dusting the cake with cocoa powder gives it an elegant finish.
Step-by-Step Instructions
Step 1: Preparing the Chocolate Sponge
The foundation of any great chocolate mousse cake is the sponge layer. A genoise sponge is perfect because it’s light and doesn’t overpower the mousse.
- Preheat your oven to 350°F (180°C). Line a 9×9-inch square cake pan with parchment paper.
- Beat the eggs and sugar together in a stand mixer or with a hand mixer. Beat on high speed for 4-5 minutes until the mixture becomes pale, fluffy, and triples in volume.
- Sift the flour, cocoa powder, salt, and baking powder into a bowl. Gently fold the dry ingredients into the egg mixture in thirds, being careful not to deflate the batter.
- Bake for 12-14 minutes or until a toothpick inserted into the center comes out clean. Let the sponge cool in the pan for 5 minutes before transferring it to a wire rack to cool completely.
This genoise sponge is incredibly versatile and can be used for other desserts as well. For example, if you’re looking for a cake that’s just as light but with a different flavor, you might want to check out this pumpkin banana loaf recipe for more inspiration.
Step 2: Making the Chocolate Ganache
The next component of your chocolate mousse cake is the ganache, which will form the base of your mousse.
- Heat the heavy cream in a small saucepan over medium heat until it begins to simmer. Do not let it boil.
- Pour the hot cream over the chopped chocolate in a heatproof bowl. Cover the bowl with a plate and let it sit for 5 minutes to allow the chocolate to melt.
- Whisk the mixture until smooth and shiny. Let the ganache cool slightly before using it to make the mousse.
Pro Tip: You can use this ganache recipe for a variety of other desserts, from truffles to tart fillings. For an added twist, experiment with different types of chocolate or add a splash of your favorite liqueur.
Step 3: Creating the Chocolate Mousse
Now that your ganache has cooled, it’s time to turn it into a delicious chocolate mousse.
- Whip the chilled heavy cream in a large bowl until it reaches stiff peaks. The key is to keep the cream cold so that it whips up light and fluffy.
- Gently fold the whipped cream into the ganache in batches. Start by adding a third of the whipped cream to the ganache and stir to lighten the mixture. Then, carefully fold in the remaining whipped cream until the mousse is smooth and well combined.
- Refrigerate the mousse for at least 30 minutes before assembling the cake. This allows it to firm up slightly, making it easier to spread.

Step 4: Assembling the Cake
With all the components ready, it’s time to assemble your chocolate mousse cake.
- Place the cooled chocolate sponge back into the cake pan or onto a serving plate.
- Spread the chocolate mousse evenly over the sponge, smoothing the top with a spatula.
- Chill the cake in the refrigerator for at least 2 hours or overnight to set the mousse.
- Decorate the cake with whipped cream, dust it with cocoa powder, or add chocolate shavings if desired.
Pro Tips for Success
- Room Temperature Ingredients: Make sure your eggs and butter are at room temperature before starting. This helps create a smoother batter and better texture.
- Don’t Overmix: When folding the dry ingredients into the egg mixture, be gentle to avoid deflating the batter. Overmixing can result in a dense sponge.
- Chill the Cake: Chilling the cake for at least a couple of hours allows the mousse to firm up, making the cake easier to slice and serve.
- Use High-Quality Chocolate: Since chocolate is the star of this dessert, it’s essential to use high-quality chocolate for the best flavor. Whether you prefer milk or dark chocolate, choosing a good brand will make a noticeable difference.
