This chocolate peanut butter mug cake is what makes having a microwave worthwhile. The cake is incredibly moist every. single. time. It has the perfect ratio of chocolate to peanut butter and it’s easy to doll up with a drizzle of peanut butter and some chocolate sprinkles. You can forget the chocolate and just enjoy a peanut butter mug cake as well.

I don’t use my microwave for most things, but I can make a mean mug cake in it!
I normally make a peanut butter mug cake, but this time I decided to get a little crazy with it and throw in a little chocolate too. I have no idea why it took me so long to add cocoa powder to my mug cake, but I’m glad it *FINALLY* occurred to me.

I would love to share like a billion more mug cake recipes. They’re so easy to whip up and if they do fail, you’re not out a ton of ingredients. That’s one of my favorite parts. I also love that it only takes a minute or so to know whether the recipe isn’t any good.
I will get downright angry if I spend a morning kneading love into a loaf of bread to find that it is a rock when it comes out of the oven. That’s like four hours of my life that I lost to a loaf of rock bread. Am I being a little dramatic? Most likely, but still!

If you’re not a huge fan of mug cakes, it’s all good. You probably just need to try this chocolate peanut butter mug cake or maybe my smores mug cake. They’re life changing, I tell you.
