The author of the recipe called this cake Heaven & Hell Cake. I call it Peanut Butter Cup Cake; layer after layer of angel food cake, devil’s food cake, and peanut butter mousse mimic a giant peanut butter cup when coated with luscious chocolate ganache.
My amazing sister saw that I pinned the cake on Pinterest and surprised me for my birthday a few weeks ago. This cake was rich, smooth, and not overly sweet. The creamy peanut butter mousse is a light, airy contrast to the deep velvety flavor and consistency of the chocolate ganache topping. The peanut butter is not heavy or hard to swallow. You do not lose the flavor and texture of the whipped peanut butter mousse while eating the cake–all of the delicious flavors stay together through every bite. Sometimes when I am eating a piece of cake I am desperately waiting to take a forkful of the back of the piece, so I can actually taste the frosting. This entire cake is flavorful and satisfying!
The only quirk with the recipe is that it makes a LOT of cake. My sister said that she had extra cake and peanut butter mousse; enough to make an entire second cake. She had a tiny bit of extra ganache, but not enough to frost that second cake. The good news is–even with less ganache, her co-workers loved their surprise “my sister’s birthday cake had enough extra cake to make you guys a second cake” cake! Peanut butter and chocolate lovers–this is your cake! It is a rich cake–so you can plan on serving a lot of people from it. Or it lasted about one week at my house for the two of us. 🙂
