I don’t know about you, but sometimes I just have the worst craving for sweets, especially cake. I love cake, and when I want it, I really don’t want the hassle of having to either bake or buy an entire cake just for my sugar fix.

This simple and delicious recipe uses boxed chocolate cake mix and peanut butter to create a single-serve dessert that is ready in literally minutes. If you don’t like chocolate, any flavor of cake mix will work. And if you can’t have peanut butter, then try almond butter or hazelnut butter in its place.
