How to Make Mint Chocolate Mousse Cake
4
Step 1: Bake the Chocolate Cake Base
Preheat your oven to 350°F (175°C). Whisk the eggs and sugar until pale and fluffy. Gently fold in the flour, cocoa powder, baking powder, salt, and melted butter. Pour the batter into a lined pan and bake until just set. Let the cake cool completely.
Step 2: Melt the Chocolate
Melt the dark chocolate using a double boiler or microwave in short intervals. Allow it to cool slightly so it blends smoothly into the mousse.
Step 3: Prepare the Gelatin
Bloom the gelatin in cold water, then gently heat until dissolved. If using agar-agar, prepare it according to package instructions.
Step 4: Make the Mint Mousse
Whip the heavy cream to soft peaks. Stir the dissolved gelatin and mint extract into the melted chocolate, then gently fold in the whipped cream until light and smooth.
Step 5: Assemble and Chill
Spread the mousse evenly over the cooled cake base. Refrigerate for at least 4 hours, or chill overnight for the cleanest slices.
Step 6: Decorate
Finish with whipped cream, chocolate shavings, and fresh mint leaves just before serving.

Tips & Variations
- Chill overnight for sharp, professional-looking slices
- Use a springform pan for easy release
- Add a thin chocolate ganache layer between cake and mousse for extra richness
- Swap dark chocolate for semi-sweet if you prefer a milder flavor
- Steep fresh mint leaves in warm cream for a more natural mint taste
Serving Ideas & Storage
This mint chocolate mousse cake is best served well chilled. Pair it with fresh berries or a glass of cold milk for a balanced dessert. Store the cake covered in the refrigerator for up to 3 days. Due to the mousse texture, this cake does not freeze well.
