Chocolate Mousse Cake

Chocolate Mousse Cake

This Mini Chocolate Mousse Cake is pure elegance in a tiny, chocolate-rich package. You get a soft, fudgy base topped with a silky mousse layer simple enough for a weeknight treat, yet special enough for celebrations.

Ingredients

For the cake layer:

  • 1/2 cup semi-sweet chocolate chips
  • 2 tbsp butter
  • 1/4 cup sugar
  • 1 egg
  • 1/4 cup all-purpose flour
  • Pinch of salt

For the mousse layer:

  • 1/2 cup heavy cream
  • 1/2 cup semi-sweet chocolate chips
  • 1/2 tsp vanilla extract
  • Pinch of salt

Optional: Fresh berries or shaved chocolate for topping
Swap: Use dark chocolate for a deeper, less sweet flavor

Steps

  1. Melt the chocolate and butter for the cake layer until smooth. Let it cool slightly so it doesn’t scramble the egg.
  2. Whisk in the sugar and egg, then fold in the flour and salt. The batter will look thick and glossy just right.
  3. Spread into a lined mini cake pan or small baking dish and bake at 350°F for 12–14 minutes. The center should look set but still soft.
  4. Cool the cake layer completely before adding the mousse this keeps the layers clean and pretty.
  5. Warm 1/4 cup of the cream and pour over the chocolate chips for the mousse. Stir until silky, then let cool to room temp.
  6. Whip the remaining 1/4 cup cream to soft peaks, adding the vanilla and salt.
  7. Fold the whipped cream into the cooled chocolate mixture gently to keep it airy.
  8. Spread the mousse over the cooled cake layer and chill for at least 1 hour.

Chef’s Tips

  • Make sure your mousse base is fully cooled before folding in the whipped cream warmth will deflate it.
  • Chill the cake at least an hour for clean slicing; overnight is even better.
  • If you prefer a firmer mousse, whip the cream slightly closer to medium peaks.

Variations

  • Mocha Mousse Cake: Add 1/2 tsp instant espresso to the mousse base.
  • Raspberry Chocolate: Add a thin layer of raspberry jam on the cake before spreading the mousse.
  • Triple Chocolate: Use white chocolate mousse on top for a beautiful contrast.

Serving Suggestion

Serve chilled with a single berry or a dusting of cocoa powder. Each mini slice feels like a tiny celebration rich, soft, and beautifully balanced.
