Banana Bread in a Mug

7 min


10 ingredients or less

One-bowl / one-pot


This banana bread in a mug is a fast-to-make, moist, and fluffy dessert. It's also a great way to use up overripe bananas, which are sweeter than unripe bananas - so they work perfectly in this recipe!

  1. To a microwave-safe mug, mash the banana with a fork until smooth.
  2. Add the milk, oil, vanilla, and salt and mix.
  3. Add the flour, flaxseed, sugar, chocolate, and baking powder and mix until just incorporated. Be careful not to over-mix.
  4. Microwave at high power (800 - 900 W) for 2 minutes or until a toothpick inserted into the centre comes out clean. The cooking time may vary depending on your microwave and settings. If the cake isn't cooked through yet, simply place it back in the microwave at intervals of 15 seconds until done.
  5. Top with sliced banana, chocolate shavings, and toasted chopped pecans if desired. Enjoy!


  • The mug might be very hot after the cake is done cooking. Be careful when removing it from the microwave.
  • If preferred, bake it in the oven at 350°F (180°C) for 15 - 25 minutes, or until a toothpick inserted into the centre comes out clean. Just be sure to use an oven-safe baking dish.


  • This dessert is best enjoyed immediately.
  • The cake can be transferred to an airtight container and store in the fridge for up to 1 day.

This was my first ever mug cake, and it was so so good! Thanks a ton, PUL! We're going to make these for our guests and friends too!

Aw so happy the first mug cake was a success! Thank YOU 😃

Made these as regular muffins in the oven and they came out perfect! So delicious 👌🏻

Jess - Aug. 24, 2021, 2:03 a.m.

I absolutely love this banana mug cake! Visiting family and friends almost always make a request for this or one of the other Pick Up Limes mug bread/cakes. Everyone gets their favorite dessert this way :-) Thank you for these recipes!!!

PUL Team - Aug. 28, 2021, 3:59 p.m.

Aw Jess, what a compliment! Thank you! 🤗

Iris - Aug. 2, 2021, 12:34 p.m.

Can you use oatmeel flower or whole spelt flower or... in stead of normal flower for the banana mug cake?

PUL Team - Aug. 5, 2021, 3:54 a.m.

Hi Iris, thanks for the question! We've had some positive reviews for the mug cakes, including this one, using oat flour in place of all-purpose flour. We haven't had a chance to test out spelt flour but if you give it a try let us know how it goes 🤗

Elena - July 30, 2021, 12:35 p.m.

I am so happy! I finally found a mug cake recipe that I was able to do and it is so good! 😍 I already made it twice 😋 Surely I will try also the other ones 🥰

PUL Team - Aug. 1, 2021, 8:44 a.m.

We're so thrilled to hear this, Elena! Do let us know how the other ones go if you give them a try ☺️

Rachelle Poat - July 25, 2021, 3:52 a.m.

My favorite mug cake ever!! It’s absolutely yummy!

Charlotte - July 9, 2021, 12:52 p.m.

I am so happy that PUL got me started on mug cake recipes as they are fun and easy to make and such a great way to enjoy cake without the time and ingredients needed to make a big one.
I am a big banana bread fan and, out of all the PUL mug cake recipes, this one is my fave. I find that it only takes 1.5 minutes at 750W in the microwave to reach perfect consistency.

PUL Team - July 13, 2021, 4:52 a.m.

Thanks a bunch for sharing this with us, Charlotte! It means so much to hear 🥳

Agata - July 8, 2021, 11:07 p.m.

That was a delicious surprise! ❤️ Thanks to this recipe I found out that it's possible to make mug desserts in the microwave. It's great as a spontaneous dessert - not much effort or many ingredients. And I love how the chopped chocolate melts! Tastes best with homemade icecream 😋

By the way, all your work - the videos, recipes, this page and more - is so impressive! Thank you so much and good luck with all your projects! Greetings from Northern Poland 😃

PUL Team - July 11, 2021, 2:44 p.m.

You're too kind, Agata! We're so happy you're enjoying the PUL content. Hugs to Northern Poland 🤗

This is perfect when you don’t have time to bake banana bread. super easy and satisfying and the amounts are perfect for one serving.

Guli - July 8, 2021, 8:53 p.m.

Made a banana mug cake this morning. Once mixed, let it stand for 5-10 minutes just so that the baking powder starts working for sure. I put a strength on 8 out of 10 on my 1200W microwave.
Baked it for 2 minutes. So delicious!

PUL Team - July 11, 2021, 12:37 a.m.

Thanks for sharing this, Guli! So glad you enjoyed the banana bread 😊

Nina - June 27, 2021, 10:16 p.m.

So good!

Paula - June 22, 2021, 6:04 p.m.

I just made the banana bread version for a quick coffee break and it’s soooo good! Thanks for that gorgeous recipe, I would recommend for anyone who loves a good homemade snack, but don’t want to stay in the kitchen for hours. 👍🏻

PUL Team - June 24, 2021, 5:49 a.m.

We're so glad you enjoyed the recipe, Paula! Thank you for taking the time to share 💖

Hana - June 20, 2021, 1:31 p.m.

This was delicious! Thanks for the recipe, it's super versatile and will definitely be one I come back to.

I made the following basic edits based on what I had in the cupboard:
- Swapped vegetable oil for coconut oil
- Swapped chocolate chips for walnuts
- Swapped all-purpose for oat flour
- Swapped soy milk for cashew milk
- Swapped sugar for maple syrup

It still came out great, if a little sweet. I think I could probably leave out the sugar/maple as I was using a very ripe banana.

PUL Team - June 21, 2021, 6:47 a.m.

Thank you for your review and for sharing this, Hana! So glad the recipe turned out with the various substitutions 😃

Cris S - June 5, 2021, 6:14 p.m.

Mine didn't came out as puffy as pictured and I'd do it sugarless, but otherwise it's very tasty!

Nehalie Gunawardena - June 2, 2021, 5:53 p.m.

This is the 5th time I made this mug cake and it never gets old. I love that the instructions are so clear. My little sister doesn't love my food cause they are usually burnt, but this time she loved it. Thank you so much.

Samonty - May 19, 2021, 2:28 p.m.

I just made this banana bread & it turned out great. My sister never eats anything banana flavoured but this time she did. Thanks.

PUL Team - May 22, 2021, 7:39 p.m.

Ooh we consider that a win! So glad you both enjoyed the banana bread in a mug, Samonty ☺️

Amy - April 24, 2021, 11:14 a.m.

Made this for a Saturday morning breakfast for my family. Was so delicious and easy! Thanks so much Sadia !! :)

PUL Team - April 25, 2021, 1:06 a.m.

The thanks is to you, Amy, and so glad you enjoyed it ✨

Darlene - April 23, 2021, 3:49 p.m.

What a awesome little treat! I like the idea of switching it up for the almond and oat flour for a breakfast switch up which I know my Granddaughter will love!.
Thanks Jasmine for the idea and thank you Sadia for the recipe. 😋

PUL Team - April 24, 2021, 3:29 a.m.

Aww we hope your granddaughter loves it, Darlene!

jasmine - April 21, 2021, 5:26 a.m.

i found this at a perfect time, as i had rather brown bananas to use up. i was feeling experimental and subbed the oil for another tablespoon of milk & used a mix of oat and almond flour instead of all-purpose. it came out delicious!

PUL Team - April 22, 2021, 3:02 a.m.

Thanks for sharing your substitutes, Jasmine! So happy you enjoyed the result :D

Hof - April 19, 2021, 4:38 p.m.

Hey! Thank you for all the great recipes!
Do you think it's possible to bake it in the oven (old school..), assuming the mug is oven safe? I don't have a microwave :(
And with what temp. and how long would you think is ideal?


PUL Team - April 20, 2021, 5:28 a.m.

Hey there, Hof! Totally - If you don't have a microwave, you can bake it in the oven at 350°F (180°C) for 15 - 25 minutes, or until a toothpick inserted into the centre comes out clean. Just be sure to use an oven-safe baking dish as you mentioned 🤗

Nina - April 19, 2021, 4:33 p.m.

Mmm so good! I think I overmixed it (my fault for being to eager not properly reading the instructions 🤦🏻‍♀️) so it was a bit stodgy, but it still tasted delish! Will definitely be making it again soon and trying out the other recipes as well 🥰

Also used this recipe as an excuse to try some gluten again as i've been wanting to reimplement it into my diet, but just small amounts at a time and this doesn't have much flour in it so it's perfect for that!

PUL Team - April 20, 2021, 5:20 a.m.

Hehe we've definitely over-mixed it for the same reason! So glad you enjoyed the recipe, Nina 🤩

Lauren - April 18, 2021, 2:51 p.m.

Hi Sadia & the PUL team, new website looks great!
If I don’t have flaxseeds for this banana bread mug cake recipe, what can I substitute that will help keep the texture?
Much love.

PUL Team - April 19, 2021, 3:18 a.m.

Hi Lauren, another ground seed, such as ground chia seeds or hemp seeds likely would work best 🙂 We hope you enjoy the recipe!

Aline - April 18, 2021, 5:44 a.m.

I just did it and it's past midnight lol. omg, this is amazing, thank you!

PUL Team - April 19, 2021, 3:08 a.m.

Hehe got to love a good midnight snack! So glad you enjoyed the mug cake, Aline :)

Amy Aossey - April 16, 2021, 8:42 p.m.

Another delicious, easy creation from Pick Up Limes! Thank you Sadia - I have never been disappointed in your recipes ❤️

PUL Team - April 19, 2021, 2:14 a.m.

We are so grateful to hear this, Amy! Thank you for the support 🥰

Nethraa - April 16, 2021, 5:58 p.m.

I just made this for my snack with coffee. Then I went back and made another mug. And then another mug hahaha it's so yummy and addictive I'm in heaven <3

PUL Team - April 19, 2021, 2:06 a.m.

Hehe third time's a charm 😜 So glad you enjoyed it, Nethraa!
