Chocolate Cake with Peanut Butter Frosting

Chocolate Cake with Peanut Butter Frosting

Since I grew up a vanilla girl, I never really invested any time in finding a good chocolate cake recipe. I just always preferred making vanilla,  carrot or banana cakes. There was no real need for chocolate. But last winter my mom told me she had heard about a chocolate mayonnaise cake and wanted me to make it. The conversation went something like this…

MOM: “It is supposed to be super moist and you can’t taste the mayonnaise.”

ME: “Mom, I am not making a cake with mayonnaise in it. That is disgusting! I can find you a much better chocolate cake.”

MOM: “But I think this recipe is going to be really good.”

ME: “Fine, you make your gross mayonnaise cake and I will make my own chocolate cake. 

Fast-forward to a few hours later, and the mayonnaise cake was in the trash and we were sitting around  devouring my cake. Maybe somewhere, someone has made an amazing chocolate cake with mayonnaise, but it is definitely not my mom, and it was definitely not the recipe she tried.

This cake is an easy one-bowl chocolate cake – and because chocolate and peanut butter is the best combination ever, I made some peanut butter frosting to go with it.
