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 (you can try my French Silk Brownie Recipe if that sounds good to you, too!).

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.
