Frequently Asked Questions
→ Can I use milk chocolate instead of dark chocolate?
You can, but the flavor will be sweeter and less intense. I recommend adding a touch more cocoa powder to balance it.
→ How far in advance can I make this cake?
The mousse cakes keep well refrigerated for up to 48 hours. Keep it covered to avoid absorbing fridge odors.
→ Do I need to use a stand mixer?
A hand whisk works, but a stand mixer makes the egg white peaks quicker and more stable.
→ Can I substitute the sponge with a gluten‑free cake?
Absolutely – use a gluten‑free vanilla loaf or almond flour cake as the base.
→ What garnish works best?
A dusting of cocoa powder, fresh berries, or a drizzle of melted chocolate adds visual appeal.
→ Is this recipe suitable for vegans?
Swap the heavy cream for coconut cream, use aquafaba for egg whites, and choose a dairy‑free chocolate.

Ingredients
Sponge Base
- 01 1 cup all‑purpose flour
- 02 1/2 cup unsweetened cocoa powder
- 03 1 tsp baking powder
- 04 1/4 tsp salt
- 05 3/4 cup sugar
- 06 2 large eggs
- 07 1/2 cup whole milk
- 08 1/4 cup melted butter
- 09 1 tsp vanilla extract
Chocolate Mousse
- 01 8 oz high‑quality dark chocolate, chopped
- 02 1/2 cup heavy cream
- 03 3 large egg whites
- 04 1/4 cup granulated sugar
- 05 1 tsp lemon juice
- 06 1 tsp vanilla extract
Ganache Topping
- 01 4 oz dark chocolate, finely chopped
- 02 3 tbsp heavy cream
- 03 1 tsp butter
Instructions
Preheat the oven to 350°F (175°C). Grease a 9‑inch springform pan and line the bottom with parchment.
In a bowl whisk flour, cocoa, baking powder, and salt. In another bowl beat sugar and eggs until pale, then add milk, melted butter, and vanilla.
Combine wet and dry mixtures, pour into the pan, and bake 15‑18 minutes until a toothpick comes out clean. Let the sponge cool completely.
Melt the dark chocolate over simmering water, then stir in 1/2 cup warm cream until smooth. Let it sit to cool slightly.
In a clean bowl whisk egg whites to soft peaks, gradually add sugar, and continue to stiff peaks. Fold a spoonful of the whipped whites into the chocolate mixture, then gently fold the rest until just incorporated.
Slice the cooled sponge horizontally into two layers. Place the bottom layer on a serving plate, spread half the mousse, top with the second sponge layer, and finish with the remaining mousse.
For the ganache, heat cream until just simmering, pour over chopped chocolate, add butter, stir until glossy, and drizzle over the cake.
Refrigerate the assembled cake for at least 2 hours. Before serving, dust with cocoa powder or garnish with fresh berries.
