Single serving Eggless Banana Chocolate Peanut Butter Mug Cake is the best, gooey and the moistest mug cake you’ll try. Ready in under 5 minutes and just needs a microwave!

I’m bringing you eggless banana chocolate peanut butter mug cake to satisfy those sweet cravings after all the healthy food we’ve been eating. Because I get it, we can’t live without our dessert. It’s the best kind of satisfaction. And I think mug cakes are so convenient. They can be almost guilt free because you don’t really need that second helping and you don’t have a second or third slice to reach for.
You remember how I spoke to you about the big 3-0 last week? Yesterday was my birthday and I had such a fabulous time. My best friends were down to visit me and help me celebrate and I’ve been super low since they left. Because we really had the best time ever. I haven’t met them in over a year and a half and as soon as we met, it was like nothing had changed. We spent hours talking and giggling over the silliest things. Best friends do that to you right? Make you forget everything else and give you a chance to just relax.
I sort of made this mug cake for breakfast – yes breakfast – no judging please- because I really needed some comfort food. To make me forget how awful it felt when your friends leave.
And this banana chocolate peanut butter mug cake is just the thing for sulking. It is so easy that it can’t even be called dessert, but it so is! Chocolatey, moist, slightly gooey and perfect when you want dessert for one.


Whoever invented mug cakes is genius. I really prefer my banana chocolate peanut butter mug cake with no eggs in it. Mug cakes are such small, single serving cakes that a tiny amount of baking soda or powder is enough to make them rise and keep them light and fluffy. An entire egg just gives mug cakes an eggy taste IMHO and is totally unnecessary.
So only a few delicious ingredients, no eggs please, and you have the lightest most chocolatey mug cakes ready in under five minutes!

I love topping mine with extra peanut butter or even chocolate chips because in our case, toppings are everything right? Since we are only talking a small dessert and not an entire cake, don’t feel guilty about adding some whipped cream, or ice cream or even extra chocolate sauce if you are into that kind of thing. Here’s to quick, easy desserts, to turning 30 and staying fabulous!

Eggless Banana Chocolate Peanut Butter Mug Cake
Ingredients
- 1/4 cup All purpose flour, or Maida
- 2 tablespoons Granulated Sugar
- 2 tablespoons Cocoa Powder
- 1/4 teaspoon Baking soda
- 1/2 Banana, Overripe mashed
- 3 tablespoons Milk
- 1 1/2 tablespoons Vegetable oil
- 1 tablespoon Peanut butter
Instructions
- In a large mug whisk together flour, sugar, cocoa powder and baking soda till combined.
- Add the mashed banana, milk, oil and peanut butter to the bowl and mix well. Microwave on high for up to a minute or minute and a half. The duration will depend on your microwave. I recommend you start checking after a minute and then microwave in bursts of 15 seconds. Serve immediately.
Notes
- Always use an overripe banana for banana cakes. This vastly changes the flavour and texture of the cake.Β
- I use small tea cups for mug cakes and this batter can be easily divided between them. However, if you are using a large mug, there is no need to divide the batter.
- Feel free to substitute whole milk for coconut milk, soy milk or any other plant based milk to make this banana peanut butter chocolate mug cake vegan.




OMG! This is by far the best mug cake recipe I’ve ever made. Moist and yummy!
The texture and taste are just nice. Definitely a keeper!
So glad you liked it Aisha!
So yummy! I love being able to make portions like this, otherwise I end up eating the whole shabang myself! Thanks for sharing!
Haha happens to everyone Erica! Which is why this Mug Cake is so awesome
Very nice!

Thanks Sacha!
I found this recipe while searching for a tasty, single-serving way to use up a banana, and I was not disappointed! I’m a cheap college student and didn’t want to buy any ingredients, so I used whole wheat flour, brown sugar, skipped the baking soda, and used water instead of milk. It was still the best mug recipe I’ve had so far! This will definitely be my new go-to for those pesky cravings. So moist and much more flavorful than other mug brownies I’ve tried. Thank you so much for sharing!
Sooo glad you liked it! Mug cakes are a lifesaver!
I agree, my favorite mug cake ever! I used liquified coconut oil for the oil. Loved it!
Coconut oil would work so well – I’ll have to try that next time! Glad you liked it Eileen
Thank you!
