Chocolate Mousse Cake

My boys love homemade chocolate mousse and they’re absolute favorite cake is my Chocolate Coca Cola Cake. It was natural to combine these two.

This cake is ideal for any celebration. It’s loaded with chocolate from top to bottom.

We also love this Chocolate Cherry Cobbler Cake for celebrations.

Chocolate Mousse Cake Recipe

For the cake, you can make a sheet cake as I did. You could also make it in 2 or 3 layers. I used Hershey’s Special Dark Chocolate Cocoa powder and Unsweetened Cocoa powder for a double whammy of chocolate. The cake is rich and decadent.

The chocolate mousse frosting adds a cool creamy texture that compliments the dense chocolate cake layer. It’s smooth, velvety, and extraordinarily delicious.

You’ll want to refrigerate any leftovers.

Tips when making the mousse

  1. First, add mini marshmallows, chocolate, and milk to a large, heavy-bottomed saucepan or large nonstick pan.
  2. Cook, stirring constantly over low heat until all the ingredients are melted and well-combined.
  3. Nex,t remove from heat and cool to warm. Here’s the secret, if it cools completely and is really cold the chocolate will not mix well into the whipped cream. Therefore, it can be slightly warm, but definitely not refrigerator cold.
  4. For the whipped cream, in a large bowl, beat the whipping cream and vanilla together until soft peaks form. Soft peaks barely hold their shape. The peaks flop over immediately when the beaters are lifted. The whipping cream will fluff up like Cool Whip if you’re familiar with Cool Whip.
  5. Next, fold the cooled chocolate into the whipped cream. Spread the frosting over the cooled cake.
  6. Chill for at least 30 minutes before serving.
  7. Finally, refrigerate any leftovers.
