Today I'm sharing the perfect treat for those days when you're craving a little something sweet but there's nary a cookie or cupcake or piece of candy in the house...Chocolate Peanut Butter Mug Cake!
Ingredients
Did you know that at any given moment, you are just a few short minutes away from straight-up, legitimate CAKE?! It's true.
As long as you're stocked with a few pantry basics, like...
- Flour.
- Cocoa powder.
- Sugar.
- Baking powder.
- Vanilla.
- Chocolate chips.
...and as long as you can rustle up a few items in the fridge...
- Milk.
- Butter.
- Peanut butter.
...then you can whip up a fresh, decadent, piping-hot Chocolate Peanut Butter Mug Cake for one (or more!) in about the same amount of time it would take to scoop a bowl of ice cream!
(And, pssst...no egg required!)
How to Make a Mug Cake
Have you made a microwave mug cake before? They're kind of magical.
For this Chocolate Peanut Butter Mug Cake, you simply:
- Stir up your simple ingredients.
- Pour your batter into a mug.
- Dollop in a swirl of peanut butter and mini chocolate chips.
- And set the microwave for a minute!
Before your very eyes, the liquid batter rises up and bakes into a rich, gooey, chocolate cake with a molten peanut butter center.
And yes, it's every bit as good as it sounds.
Making Multiple Mug Cakes
If anyone else in the house shares your sweet tooth, you can easily double, triple, or quadruple this recipe.
Simply divide the batter between the corresponding number of mugs and microwave them one at a time.
With each cake only taking one minute to bake, you'll still have dessert ready in a matter of minutes.
Ways to Enjoy It
And it's up to you how you prefer to enjoy these little babies.
You can eat your dessert straight out of the mug (which is what I typically do).
Or if you're feeling fancy and don't mind dirtying one more dish, you can spray your mug with cooking spray before adding the batter and then overturn your cake onto a plate once baked for a quick take on a molten lava cake.
Well, hello there, lovely. Don't mind if I do.
Regardless of how you choose to serve them, any fan of chocolate and peanut butter won't want to miss these to-die-for mug cakes!
After all, it's hard to beat fresh, hot, chocolate cake goodness, but if anything can, it would be a peanut buttery center.
And the fact that a Chocolate Peanut Butter Mug Cake can be ready -- from start to finish -- in under five minutes?
Well, that sounds like a pretty perfect way to satisfy a rogue sugar craving to me. 😉

Chocolate Peanut Butter Mug Cake
Ingredients
- ¼ cup all-purpose flour
- 2 tablespoons unsweetened cocoa powder
- 2 tablespoons sugar
- ¼ teaspoon baking powder
- ¼ cup milk, at room temperature
- 2 tablespoons butter, melted and cooled
- ¼ teaspoon pure vanilla extract
- 1 tablespoon creamy peanut butter
- 1 tablespoon mini chocolate chips
Instructions
- In a small bowl, whisk together flour, cocoa powder, sugar, and baking powder until thoroughly, completely combined with no streaks of flour or cocoa powder remaining. Blend in milk, butter, and vanilla until batter is smooth. Pour batter into a 14-ounce (or larger) microwave-safe mug with straight sides.
- Combine peanut butter and chocolate chips and dollop into the center of the mug, gently pressing down until even with the top of the batter. Microwave on high for 1 minute. Allow to cool for a couple of minutes before serving.
Notes
- A tall, cylindrical mug with straight (not angled) sides will ensure that the cake bakes evenly. I found a 14-ounce mug to be the perfect size to allow the cake to rise up while baking without overflowing. (I filled my mug to the top with water and then transferred the water to a measuring cup to determine its capacity.) If you use a smaller mug, you may want to bake the cake on top of a plate or paper towel to catch any possible overflow.
- The strength of individual microwaves can vary. The first time you make this recipe, be prepared to experiment a bit to make sure that 1 minute is the perfect length of baking time. The nice thing about this cake is that even if it is undercooked, you don't have to worry about raw eggs!
- The mini chocolate chips are optional. So is the peanut butter, for that matter. But I don't recommend skipping either. 😉
- As an alternative to serving straight out of the mug, you may instead spray the mug with non-stick cooking spray before adding the batter, and then carefully overturn the cake onto a plate once baked.

This is so good. I am mad at myself for finding this recipe! haha. It is delicious!! 🙂
Ha, Allison...it's kind of addictive, isn't it? If only I had made this mug cake harder to make, it might be easier to resist! Hope you enjoy it anyway...in moderation, of course. 😉
This is my go to recipe for chocolate mug cakes. Thank you!
I've made this like 5 times now! It's so good!!!
Yay, Erica...I'm glad to hear it's been such a hit! I have to admit that this mug cake is a regular inhabitant of my microwave as well...but usually after the kids go to bed -- ha! 😉 Thanks for taking the time to comment...hope you're having a great week!
I just made this yummy cake without the PB and a little extra chocolate chips, so good!! This definitely satisfied my chocolate craving. Yum! Thanks so much for the recipe. 🙂
You are very welcome, Becky! You can never go wrong with all chocolate, and this is definitely an easy fix for a chocolate craving! 😉 I'm so happy to hear that you enjoyed it!
Wow, I never realized you could make cake in the microwave. This is a great idea! I pinned and hopefully will be making soon.
Ha, Alex...I know! The ability to make one-minute, microwaveable cake is dangerous knowledge. 😉 Thanks so much for the pin and I hope you enjoy this recipe when you have a chance to try it. Happy Friday! 🙂
Please could you measure your '1/4 cups' etc and convert into ounces and mls for us Brits please?
thank you 🙂 x
Hi Lynn! As much as I would love to be able to do that, I'm just not comfortable enough with metric conversions to feel confident that I would be consistently accurate in my recipes. I would hate for somebody to cook something using my less-than-perfect metric conversions and it turn out a mess! Hopefully I can take on this additional task in the future when I'm in a position to hire some help. 😉 In the meantime, I hope you're able to find a chart or calculator to help you out so that you can try some non-metric recipes. 🙂
Why does the milk have to be room temperature? I don't want to wait for the milk to warm up. Can I just use it cold or nuke it a few seconds?
Hi Liz! Yes, you can absolutely warm up your milk in the microwave for a few seconds. In fact, that's what I typically do. I just find that cold ingredients often result in a lumpy batter, so I recommend room temperature for most of my baking recipes. But I usually take short cuts to get everything to room temperature. And you can definitely live on the edge and start with everything cold if you prefer. 😉 Thanks for the question...hope you enjoy this mug cake if you have a chance to try it, and hope you're having a great weekend!
Just made this, a little skeptical...but YUM! It came out perfect. Thanks! 🙂
Yay! I'm happy to hear that you enjoyed this recipe, Jamie! It does seem a little crazy that a cake you microwave for a minute could turn out tasty, but this one has made me a believer. 😉
Oh Sam! This looks simply divine! Your photos are always so amazing. I made one of these a while back, but don't know where the recipe went, so am making this soon. Perfect that it's choc/pb combo and single serving too. <3 it! So glad you shared this at Weekend Potluck.
Thanks so much for the sweet comment, Marsha...I hope you enjoy this if you have a chance to try it! Thanks for stopping by...I continue to hold you and your family in my prayers.

Enjoy, Marsha...and hang in there. I'm so impressed by your strength and grace through this difficult time.
I couldn't do it without HIS strength that is made perfect in my weakness. Thanks for more ♥ warming words. :-*
You are out of control! This sounds absolutely heavenly. I can't get enough of the PB and Chocolate combo. Pinning!

Thank you, Erin! I appreciate the pin and I hope you love this cake when you try it. 🙂 Happy Friday!
OMG this is too too too dangerous. Why did you post this recipe? Of course I get a craving and I deliberately keep the house barren of goodies except for low fat yogurt. NOW I am in BIG trouble. They look so warm and deliciously gooey. Oh dear. Seriously what a fun recipe and technique.
Ha ha, Carol...so sorry to bring such temptation your way! If it makes you feel any better, my healthy eating resolution is worse off for knowing about this recipe as well... 😉
I love this! Do you think peanut butter chips in the middle would also work?
The peanut butter literally flowing out is calling to me!
Hi Mir! I think you could put just about anything in the center of one of these mug cakes...peanut butter chips, chocolate chips, chocolate candy, Nutella, Biscoff, etc. Or leave it plain and it would still be good! Have fun experimenting... 🙂
Yum, it is great to have a recipe like this one ready for when the old sweet tooth starts playing up 🙂 I can't wait to try it out!
Thanks, Kaylene! I agree...everyone needs a quick and easy dessert recipe for emergency situations. 😉 Hope you enjoy this one!
Looks delicious! I always find these dangerous! Too easy to make all the time but so good to have when you need a sweet treat!
I am with you, Kathy...these mug cakes are totally dangerous, but I can't say I'm sorry to have them in my life -- ha! 😉 Hope you're having a great week!
