A chocolate peanut butter mug cake that takes just a few minutes to make and cooks in the microwave. This is a great way to treat yourself when you’re craving something sweet.
I love mug cakes. They are so easy to make and require very little clean-up. It takes a few minutes to put together and only about 1 minute of cooking time. Whenever I’m craving a sweet treat for one, I turn to a mug cake.
The other day I experimented with some other flavor mug cakes. So far I’ve made nutella chocolate mug cake and chocolate mug cake. I set about trying to make a peanut butter chocolate one.
Ingredients
Ingredients- All-purpose flour
- White granulated sugar
- Baking powder
- Egg
- Cocoa powder
- Peanut butter
- Milk
- Melted butter
Recipe Steps
Whisk all of the ingredients in a large mug.
Microwave the mug cake on high for about 1 to 1 1/2 minutes. You don’t want to overcook it or it will become rubbery.
Let it cool off before enjoying.
The cake came out a little bit dryer than I had been expecting and the peanut butter flavor wasn’t intense enough for my personal preference. It was still a tasty cake though and really hit the spot. Next time I think I might not mix the peanut butter into the batter, but instead swirl it in.

Love the mug cakes! Love peanut butter cake. Here is the dry cake solve: No egg. No butter. 3 tablespoons applesauce, 1 tablespoon oil, 3 tablespoons melted peanut butter. 2 tablespoons packed cocoa powder and 5 tablespoons ap flour. Then follow the rest of your recipe. *spray inside of coffee mug with non-stick spray and mix batter in small bowl first.*
thanks for sharing. this is actually quite an old recipe. I’ve definitely figured things out since. If you look through my mug cakes category you’ll find my updated recipes where I’ve solved a lot of previous issues.
This was fantastic! I added about a quarter teaspoon of vanilla and a pinch of salt, and used half brown sugar and half white. I think next time I may reduce the quantities slightly because it turned out being more like two servings of cake than like one, but it was delicious.
Yeah it’s definitely enough for two people to share! Thanks for letting me know of the tweaks you made.
I put the peanut butter on the bottom instead of in it and it melted all over when fljpped upside down YUMMY!!!!!
Oh interesting. I will have to try that next time.
I just made this, minuses the sugar as I’m diabetic and used 3 table spoons of Splenda. I also added a dash of cinamon and vanilla and ate it with a small scoop of sugar free vanilla icecream. Perfect snack!
Yay! Glad you liked it
I just made this, we didn’t have enough cocoa to put cocoa in it, and we didn’t have baking powder, it works just as well replacing the flour and baking soda with four tablespoons of self raising flour. It is so tasty!
Yay! Yes, self raising flour should work so I’m glad it did
This was super easy and very yummy. I didn’t have any milk so I just used water and it came out perfect! So happy I found this site with it’s different takes on the mug cake, will definitely be trying the other variations in the future.
Glad to know it still works with water!
It didn’t fit in my mug, but it tasted amazing.
Yay!
This is delicious! I made it and it was just a little undercooked so it was moist and chewy! yum!
So glad you like it!
I know that it’s weird but I don’t have a mirowave so I only can use oven. Do you think that it could work?
Hmm, I assume it would work in an oven but the baking time would be different. I’m not sure how it will turn out though
I do something similar with protein powder and peanut butter – probably doesn’t taste nearly as good though 😀
Hmm..I’ve never added protein powder to desserts so I don’t know, but I’m thinking not..
Looks great and sounds really easy but I don’t envy the person that has to wash that mug. It must stick something awful.
It’s actually not too bad. If you wash it after you are done and use the scrub portion of the sponge it comes off pretty easily.
What a cool idea! I’ve never tried making a mug cake before, but it’s hard to go wrong with anything that has cocoa powder and peanut butter in it. Do you think you could use oil instead of melted butter in this recipe?
Hi Matt- I think oil would work. I’ve done other mug cakes that use oil instead of butter so it should be okay.
