One-Minute Chocolate Peanut Butter Mug Cake is a moist chocolate cake with a molten peanut butter center that quickly bakes up in a mug in the microwave!
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.
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 and sugar, and as long as you can rustle up a bit of milk and butter, you can whip up a fresh, decadent, piping-hot dessert for one (or more!) in about the same amount of time it would take to scoop a bowl of ice cream.
Have you made a microwave mug cake before? They're kind of magical. For this version, you just stir up your simple ingredients (this recipe doesn't even require an egg!), 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.
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.
And it's up to you how you prefer to enjoy these little babies. You can eat your cake 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 these 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. 😉
One-Minute Chocolate Peanut Butter Mug Cake Recipe
One-Minute Chocolate Peanut Butter Mug Cake
Ingredients
- 1/4 cup all-purpose flour
- 2 tablespoons unsweetened cocoa powder
- 2 tablespoons sugar
- 1/4 teaspoon baking powder
- 1/4 cup milk, at room temperature
- 2 tablespoons butter, melted and cooled
- 1/4 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.

10/10 love it, would recommend xx

My peanut butter hardened instead of melting, not sure why. Might have to do with using natural peanut butter since it tends to be drier. Besides that, this recipe is great! The texture of the cake is wonderful, it tastes great without being too sweet, and it doesn't dry out. I had to microwave it for about 1:30.

Made it just now with homemade peanut butter. The kids are going crazy over it. Making more right now

Hi,
Just tried this peanut butter chocolate mug cake and let me say that I am impressed! Unfortunately, we were out of milk, so I used a vanilla yogurt in place of it in the same amount, and I was pleased to find it created a creamy consistency with a little bit of tang. While creating this, the yogurt along with the dry ingredients reminded me of the consistency of fudge. Any chance for a yogurt fudge recipe coming soon?!?! Thanks so much loved this recipe!!!

My husband and I have made this recipe twice, following the recipe exactly (besides the microwave time since they vary, so we cook them for more like one minute and forty-five seconds), and we absolutely LOVE them! We shared this recipe with our whole family. The cake is rich and fudgy, the center melting into a chocolate peanut butter sauce, and it is the perfect amount for one serving. Thanks for sharing this recipe!

Love this! I make it more often than I probably should. I think using real butter vs oil that a lot of mug cakes call for makes a big difference! This is so moist and the melted peanut butter in the middle is deadly! Thank-you for such a delicious recipe!

Delicious! I halved because my mugs are smaller and used almond milk. Also no minichips and full size ones worked fine.

I made this using Hershey special dark cocoa powder and snickers peanut butter (about two tablespoons cut up) and drizzled Carmel on top after I cooked it, it was AMAZING! The dark cocoa kept it from being too sweet!
