Why You’ll Love This Mint Chocolate Mousse Cake

It brings the perfect balance between rich chocolate and fresh mint, a duo that never fails to impress. The mousse is silky smooth, the cake is moist and light, and the combination is simply irresistible. It’s also a great make-ahead dessert that stores beautifully and holds its shape when sliced.

What Kind of Chocolate Should I Use?

For the most decadent flavor, opt for a high-quality dark chocolate with around 60-70% cocoa for the mousse layer. For the cake base, a rich Dutch-processed cocoa powder delivers a deep chocolate flavor and a smoother texture. Avoid overly sweet chocolate, as the mint brings its own brightness.

Ingredients for the Mint Chocolate Mousse Cake

This dessert is built in layers, each bringing its own flavor and texture. Using fresh ingredients and quality chocolate makes all the difference.

• Dark chocolate
• Heavy cream
• Eggs
• Granulated sugar
• Cocoa powder (Dutch-processed)
• Peppermint extract
• All-purpose flour
• Butter
• Salt
• Baking powder
• Vanilla extract
• Gelatin (optional, for stability)

Each of these ingredients contributes to the structure or flavor. The peppermint extract is key for that cool freshness, while gelatin (used in the mousse) helps it hold shape especially if you plan to unmold the cake for presentation.

How To Make the Mint Chocolate Mousse Cake

Step 1: Bake the Chocolate Cake Base

Prepare your cake pan by greasing it and lining the bottom with parchment paper. Mix your dry ingredients in one bowl: flour, cocoa powder, baking powder, and salt. In a separate bowl, cream together butter and sugar until fluffy. Add in eggs one at a time, followed by vanilla extract. Slowly add the dry ingredients and mix until just combined. Bake at 350°F for about 20 minutes. Let it cool completely.

Step 2: Prepare the Mint Chocolate Mousse

Melt the dark chocolate gently in a heatproof bowl over simmering water, then set aside to cool slightly. Whip heavy cream to soft peaks and chill. In another bowl, beat egg yolks with sugar over a double boiler until thickened and pale. Add peppermint extract. Fold in melted chocolate, followed by whipped cream. Optionally, bloom and melt gelatin and stir in for added firmness.

Step 3: Assemble the Cake

Place the cooled cake base in a springform pan. Pour the mousse on top, spreading evenly. Tap gently to release air bubbles. Chill for at least 4 hours, preferably overnight.

Step 4: Decorate and Serve

Once fully set, remove from the pan and top with chocolate shavings, mint leaves, or a drizzle of ganache if desired. Slice and serve chilled.
