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.


  • 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.

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

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. 😋

Aww we hope your granddaughter loves it, Darlene!

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!

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

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 🤗

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 🤩

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!

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