Chocolate Mousse Cake

This easy chocolate mousse cake recipe makes a moist dark chocolate cake that’s topped with a yummy chocolate mousse.

I’ve been in a chocolate mousse kinda mood lately.

At first, I thought I’d make a French Silk Pie. I wanted something rich and chocolaty, and French Silk Pie came to mind.

Since my birthday was coming up, I finally ended up settling on this Chocolate Mousse Cake. And it was an awesome decision.

This cake is moist and intensely chocolaty. It’s topped with a super rich and creamy chocolate mousse for the ultimate chocolate dessert!

And all of that chocolate in one little piece of cake meant a very happy birthday for me.
