Banana Bread Mug Cake (Vegan)
What is a mug cake?
In case you don’t know, a mug cake is exactly what it sounds like. A quick single-serving cake that’s usually whipped up in your mug and cooked quickly in it too. It usually takes about a minute to two minutes to make, and the result is a fully cooked, delicious and moist mini cake. I’ve made one before that’s the #1 search result for vegan brownie mug cake, so be sure to check that one out too.
Needless to say – mug cakes are incredibly convenient and so tasty! You usually only one a single serving anyway, and the overall time is always less than 5 minutes to make!
Ingredients in Banana Bread Mug Cake
- Banana – ah yes, the key ingredient here. The banana here acts as a binder, a flavouring agent, and so much more. I highly recommend using a very ripe banana, and measuring out yours. You want to ensure that your banana is very mashed, and that you measure the amount of the mashed banana, not the amount before mashing.
- Flour – you can sub gluten-free flour, just be sure to see if it needs a bit more baking time (about 10 seconds more) but don’t overbake. It’s okay if there is a tiny bit of gooey liquid on top – it’ll set while cools.
- Sugar – I only use 1 tablespoon because of the sweetness of the bananas. If you think you’d like something sweeter, you can add an extra tablespoon!
- Oil – adds to the moisture and texture of the mug cake. You can use any neutral oil that you have!
- Almond milk – adds some moisture to the mug cake. You can sub any other nut milk or soy milk that you have.
- Sea salt – a dash always elevates flavours, don’t skip it!
- Baking powder – aids in the rise of this mug cake and to help with the texture. P.S. be sure to test your baking powder before using it to ensure it’s fresh.
- Cinnamon, walnut & chocolate chips – optional, but amazing add-ins that take it over the top. I highly recommend at least the cinnamon!
Tips for making mug cakes
Making a mug cake is pretty much foolproof, but these few tips help to make a big difference. I’ve tested mug cakes over 2 dozen times (yes!), and here are the top tips I took away:
- Use a wide short-ish mug (like the one in these photos!). If you have a variety to choose from, using this type of mug means the cake rises higher in a concentrated space. I’ve found this helps with cooking.
- Ensure to stir it all together. Don’t go whisking it for minutes on end, but ensure your entire mug cake is mixed. Since it’s such a small container it can be easy to miss the bottom. Just ensure you incorporate everything.
- Adjust your time based on your microwave. The times I’ve provided should work but yours may need an extra 10 seconds. It’ll cook edges to centre so just check the centre that it’s fully cooked…BUT:
- BUT, don’t overcook. This will make your mug cake gummy and rubbery. Remember that the mug cake will keep cooking while it’s cooling so it’s better to slightly under bake it.
- Let it cool for like 3 minutes before digging it. It really does make a difference, like how you’d let a cake or brownies cool first!
- I’ve included instructions for baking this in your oven too! Similarly here, be sure to slightly underbake (you don’t want your toothpick to come out clean, it should still have crumbs attached) since it’ll continue to cook while it cools.
That’s it friends! Whip this up and enjoy so much!!

Banana Bread Mug Cake (Vegan)
- 1/3 cup mashed bananas, about 1 very ripe banana, but be sure to measure it out
- 1 tablespoon oil
- 1 tablespoon almond milk , or other vegan milk
- 1 tablespoon raw brown sugar, or coconut sugar or other granulated sugar
- 3 tablespoons all-purpose flour, or all-purpose gluten-free flour mix*
- pinch of sea salt
- pinch of ground cinnamon
- 1/2 teaspoon baking powder
- Optional: 1 tablespoon chopped nuts and/or chocolate chips
- In a mug, add in the mashed banana, oil, milk and sugar. Whisk together for about 30 seconds to combine completely and banana is completely mashed. Add in the flours, baking powder, salt and cinnamon.
- Stir to combine for about 20 more seconds to ensure it’s all incorporated, ensuring the get the bottoms too. Add in the nuts & chocolate chips if using and fold in. Feel free to sprinkle some of them on top.
- Place in your microwave for about 80 seconds. It's okay if it's slightly undercooked because it'll continue to cook while it cools. It's better for it to be slightly undercooked than overcooked. Remove and let cool for about 3 minutes. Trust me! If making in your oven, preheat oven to 350F and bake in about a 3.5-inch ramekin (ensure it's oven safe) for 25-30 minutes. Remove and allow to cool for about 5 minutes. Sprinkle some coarse sea salt on top and enjoy!

Very veryyy good
I really liked this recipe! I actually let it sit for about 5min after it was done, and it was perfect!
Microwaves vary. Mine took about 2 1/2 minutes.
I forgot about a banana in my backpack for a couple of days and it got too overripe for me to eat. This was the perfect solution to that dilemma. I followed the recipe to the letter, but I gave it an extra five seconds for high-altitude baking. Sooo good, will make again.
I loved it – replaced sugar with erithritol and halved the oil and it still turned out great. Albo, baked it in the air fryer.
Really good! I added a little walnuts/choc chips and 80 seconds and sitting for 3 min was really good! Definitely satisfied my craving! Thanks!
Both my wife and I loved this for an easy, quick dessert. Directions and ‘baking’ times were perfect for our microwave. On second batch, we toasted pecans in the air fryer for one minute which really enhanced their flavor.
Sounds delicious. Do you have the nutrition info?
Hi Beth thanks so much for reading. The Nutritional info is near to the bottom of the page right below the notes. I hope this helps.
Help I don’t have a microwave (long story) can I do this in the oven? If so what temp for how long?
Hi Cecilia in the instructions it gives an oven option. I hope this helps. Thanks so much for reading!
A most excellent treat! Thank you!
