Chocolate Cake with Peanut Butter Frosting – this homemade chocolate cake is made in a 9×13″ pan, so it is extra easy to prepare and serve. The creamy peanut butter frosting is absolutely heavenly!

My fourth son loves chocolate and peanut butter. (He takes after his mamma in that regard.) Every year he asks for a chocolate cake with peanut butter frosting. For the past two, maybe three years, I’ve made him this Reese’s peanut butter chocolate cake.
This year I was hoping to switch it up just a little. I happened to have Reese’s Pieces on hand. When I asked if he’d be okay with a non-layered cake if it had candy on top, he was happy to oblige. Because what kid won’t opt for extra candy? None of mine.
This cake is super simple to make. It starts with a chocolate cake recipe that I got from my mom. I tweaked it a bit, but it is basically the same delicious cake that I had more times than I can count when I was growing up. We called it Texas Sheet Cake, and topped it with a warm chocolate frosting. It is just as yummy in this recipe. 🙂

This is a very moist and tender cake, which is just how I like cake. I’m not a fan of fluffy cakes if they are dry AT ALL. Plus I love that you serve it right from the pan. No greasing and flouring cake pans and lining with parchment paper. No worries that your cake is going to stick to the pan when you flip it over. Sometimes simple and stress-free cooking is the way to go!
The peanut butter frosting on the top is creamy and sinfully yummy. I could (and did) eat a few spoonfuls. It is perfect on top of this cake. Kids love the candy on top, and I think it gives the cake a fun element, but the cake and frosting really could stand alone. Unless you’re making it for a ten year old’s birthday party. 🙂

Whoa, sorry Andrea. Not sure what happened, but the instructions disappeared! I added them again, so hopefully they’re here to stay this time. 🙂
