Ingredients Overview
For the Cake Base:
1 cup all-purpose flour
½ cup cocoa powder
1 teaspoon baking powder
½ teaspoon baking soda
¼ teaspoon salt
¾ cup sugar
2 large eggs
½ cup milk
¼ cup vegetable oil or melted butter
1 teaspoon vanilla extract
½ cup brewed strong coffee or espresso (cooled)
For the Mocha Mousse:
1 cup heavy cream (cold)
1 teaspoon instant coffee or espresso powder
4 oz dark chocolate (chopped)
2 tablespoons sugar
1 tablespoon unflavored gelatin
2 tablespoons water (for blooming gelatin)
Optional: extra cocoa powder or chocolate shavings for topping
How to Make Mocha Mousse Cake
1. Prepare the Cake Base
Preheat your oven to 350°F (175°C). Grease and line a springform pan. In a bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt. In another large bowl, beat eggs and sugar until light and fluffy. Add milk, oil, vanilla, and coffee. Fold in the dry ingredients until just combined. Pour the batter into the prepared pan and bake for 20-25 minutes, or until a toothpick inserted comes out clean. Let cool completely.
2. Make the Mocha Mousse
Melt dark chocolate in a heatproof bowl over simmering water or in the microwave. Set aside to cool slightly. Bloom gelatin by sprinkling it over 2 tablespoons water and let sit for 5 minutes. In a small saucepan, dissolve espresso powder and sugar in 1 tablespoon hot water. Stir in the bloomed gelatin and melted chocolate until smooth. Let cool. In a separate bowl, whip heavy cream to soft peaks. Gently fold the whipped cream into the cooled chocolate mixture until light and fluffy.
3. Assemble the Cake
Place the cooled cake back in the springform pan. Spread the mocha mousse evenly over the cake layer. Smooth the top and refrigerate for at least 4 hours or overnight until set.
4. Decorate
Before serving, dust with cocoa powder, add chocolate shavings, or pipe whipped cream for extra flair.
