- ½ cup (100g) granulated sugar
- ¼ cup (30g) cocoa powder (if making a chocolate cake)
- 1 teaspoon baking powder
- ¼ teaspoon salt
- 2 large eggs
- ½ cup (120ml) milk
- ¼ cup (60ml) vegetable oil
- 1 teaspoon vanilla extract

- 1 ½ cups (360ml) heavy cream, cold
- 1 cup (180g) semi-sweet chocolate, finely chopped
- 2 tablespoons powdered sugar
- 1 teaspoon vanilla extract

Step-by-Step Instructions for Mousse Cake
Step 1: Prepare the Cake Base
1. Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan and line the bottom with parchment paper for easy release.
2. Mix the Dry Ingredients
In a large mixing bowl, whisk together the flour, cocoa powder (if making a chocolate base), sugar, baking powder, and salt until well combined.
3. Combine the Wet Ingredients
In a separate bowl, whisk together the eggs, milk, vegetable oil, and vanilla extract. Add the wet ingredients to the dry ingredients and stir until just combined. Be careful not to overmix the batter, as this can result in a dense cake.
4. Bake the Cake
Pour the batter into the prepared cake pan and bake for 20–25 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely on a wire rack.
Step 2: Make the Chocolate Mousse
1. Melt the Chocolate
In a heatproof bowl, melt the chopped semi-sweet chocolate over a pot of simmering water (double boiler method) or in the microwave in 30-second intervals, stirring until smooth. Set aside to cool slightly.
2. Whip the Cream
In a large mixing bowl, whip the heavy cream with a hand mixer or stand mixer until soft peaks form. Add the powdered sugar and vanilla extract, then continue to whip until stiff peaks form. Be careful not to overwhip, as you want a light, fluffy texture.
3. Fold in the Chocolate
Once the chocolate has cooled slightly, gently fold it into the whipped cream using a spatula. Work carefully to preserve the airiness of the mousse.
Step 3: Assemble the Mousse Cake
1. Level the Cake
If the cake has domed on top during baking, use a sharp knife to trim the top so that it’s level. This ensures even layers for your mousse cake.
2. Add the Mousse
Spread an even layer of the chocolate mousse over the top of the cake base. Use a spatula to smooth the mousse layer, ensuring it covers the entire surface of the cake.
3. Chill the Cake
Place the assembled mousse cake in the refrigerator to chill for at least 4 hours, or overnight if possible. This allows the mousse to firm up and the flavors to meld.
Step 4: Add the Finishing Touches
Once the cake has chilled and the mousse has set, you can add any finishing touches you like. Dust the top with cocoa powder, add shaved chocolate, or decorate with fresh berries or whipped cream for a beautiful presentation.
Step 5: Slice and Serve
When ready to serve, slice the cake with a sharp knife, wiping the blade clean between cuts to ensure neat slices. Enjoy the light, airy mousse combined with the rich cake base for a decadent dessert experience!
Tips for the Best Mousse Cake
1. Use Quality Chocolate
For the mousse, using high-quality chocolate will make a big difference in flavor. Opt for semi-sweet or dark chocolate for a rich, decadent taste.
2. Make Sure the Cake is Cool
Allow the cake to cool completely before adding the mousse. If the cake is even slightly warm, it can cause the mousse to melt and not set properly.
3. Chill for the Best Texture
Chilling the cake is key to allowing the mousse to firm up and hold its shape. Don’t skip this step, as it’s essential for the cake to slice cleanly and for the mousse to be light and airy.
4. Try Different Flavors
This recipe is versatile! Instead of chocolate mousse, you can try making a vanilla mousse, strawberry mousse, or even coffee mousse for a different twist. Simply adjust the ingredients in the mousse layer according to your flavor preference.
Variations of Mousse Cake
Mousse cake is incredibly flexible, and you can experiment with various flavors and fillings. Here are a few delicious variations to try:
1. White Chocolate Raspberry Mousse Cake
Swap the semi-sweet chocolate in the mousse for white chocolate, and fold in fresh raspberries for a light, fruity twist. The sweetness of white chocolate paired with the tartness of raspberries is a perfect balance.
2. Coffee Mousse Cake
For coffee lovers, add espresso powder to the mousse and use a coffee-flavored cake base. This variation creates a rich, mocha-like dessert with layers of coffee-infused flavor.
3. Lemon Mousse Cake
For a refreshing and citrusy take, make a lemon mousse by adding lemon zest and juice to the mousse layer. Pair it with a vanilla cake base, and garnish with lemon slices or zest for a bright, zesty dessert.
4. Triple Chocolate Mousse Cake
For the ultimate chocolate lover, layer dark chocolate, milk chocolate, and white chocolate mousse on top of a chocolate cake base. This triple chocolate delight is rich, indulgent, and perfect for special occasions.
