This gooey banana mug cake is the perfect treat to cook yourself when you’re feeling a little hungry. It’s also a great quick, and easy dessert that you can cook up after dinner.
By the time you’re ready to eat this cake, it should be moist, fluffy, and packed with that lovely banana flavor we all know and love.
This mug cake is so delicious it’s hard to resist making it every night. It only takes just a few simple steps, a few ingredients and a minute to cook. The result is a sweet cake that is incredibly moist, and it’s the perfect treat to give yourself after a long day of hard work.
Extras to have with this Mug Cake
Usually, you can enjoy these tasty cakes just on their own, but if you want to take it to the next level, then a scoop of vanilla ice cream goes perfectly on top.
It also goes great with some hot custard, but that involves more work unless you buy the premade custard. You could go one step further and have it with some banana custard. It would be the ultimate banana snack.
The easiest extra that you can have with this delicious cake is some cream drizzled over the top. Any cream will work, but I suggest using something without any sweetener.
if you have any suggestions for what else to have with this cake, then I would love to hear them.
One serving of this banana cake will only feed one person unless you’re not feeling very hungry then you might be able to feed two.
If you want to cook for two then just double the recipe and split it across two mugs. You may need to adjust the cooking time.
You can also make this in a bowl if you need to feed lots of people, but at that point, you might just want to make a full dessert such as sticky date pudding.
Personalize this Cake
There are so many slight changes that you can make this recipe so that it will better suit what you’re after. I will quickly go through a few of my favorite variations.
Adding some chocolate chips to the cake mixture will give you a delicious cake that is similar to the cookie dough in a mug. The chocolate chips melt and will leave you with gooey bits of chocolate throughout the banana mug cake.
If you want no eggs in this recipe, then leave the egg out. The cake should still cook to be gooey and moist. If the batter ends up a little too dry then simply top up with some more milk.
Let us know of any variations that you enjoy with this recipe. I only touched on a few, and I know there is so many more.
Overripe Bananas Work Best
For this banana mug cake to work the best, you will need to use overripe bananas. If they’re unripe, then they will not mash properly. Unmashed bananas leave you with a very unsatisfying cake as you won’t get the smoothness and sweetness from the banana that you require.
There are plenty of sweet baked goods you can make with overripe bananas.
If you have a ton of bananas that you need to use and want to do more than just this mug cake, then be sure to take a look at the fantastic banana bread. It too is incredibly easy but will need to be cooked in a traditional oven rather than the microwave.
The video below will show you the few steps to whipping up this tasty dessert in a mug. If you prefer to read, then you can find the full written recipe right underneath the video.
Banana Mug Cake Recipe
- 1 Tbsp butter, melted
- 1 egg
- 1 Tbsp milk
- 1 ripe banana, mashed
- 3 Tbsp plain flour
- 2 Tbsp brown sugar
- ½ tsp baking powder
- Firstly, melt the butter in the microwave. (Roughly 10 seconds)
- Beat in the egg and banana.
- Add the dry ingredients, milk, and mix until combined.
- Cook in the microwave for 1 minute and 30 seconds. Cook further, if not fully cooked.
- Serve & Enjoy
- If you like your mug cakes slightly gooey in the middle, then reduce the cooking time slightly.
- For the best results use an overripe banana.
- Add a drop of vanilla extract for a bit of extra flavor.
- You can make this banana cake gluten-free by replacing the flour and baking powder with gluten-free variants.
- Mug cakes can make a mess in your microwave so keep an eye on it. Placing a plate under the mug will make cleaning up easier if it does end up overflowing.
- Use a skewer to ensure that the middle is fully cooked. The skewer should come out clean. This step is essential if you can’t eat any undercooked egg.

I love cooking mug cakes as they’re so easy to make and they’re the perfect comfort food. Another one that I highly recommend that you try is the breakfast oatmeal, it too uses banana and is delicious.

Very satisfying cake. I threw some chocolate chips in the final stir and it turned out delicious. I also topped with a sugar syrup after the cake had cooled a little. I was full after consuming half the cake and had to finish the rest about an hour later it was so yummy! Thank you so much!
This recipe is delicious. I used almond milk, a tablespoon of oil instead of an egg, and added a tablespoon of cocoa powder. Delicious!
Hello and thank you!
Would this work in a toaster oven instead of microwave, to make it healthier? (If yes, what temp and time?)
I needed something sweet to eat but I am on a soft food diet and this was perfect! Very easy and quick to make. I will keep this around and add extras to it for my tastes. Thank you so much!
I added a few walnuts… it was very tasty!!
Amazing! I got the quantities wrong the first time but it showed so much promise I tried again and it was perfect! Like others here I wasn’t really sure what to expect but it just works. I will experiment with new ingredients… Many thanks!
It turned out really well. I needed a big mug! 850 Watt microwave took 2 minutes to cook. I used a small banana and forgot the milk. Still, it was very good.
I use this recipe every weekend! I love it! I’ve been trying out new things to add to it and I’ve come up with a few good combinations.
– put a dollop of biscoff spread in it before baking, it’ll give you a gooey center. or just add it after baking as a topping
– bananna still a bit hard? bake them with some sugar before putting them in. it’ll give you a nice caramel flavour.
– caramel/ toffee / dulce leche
– throw in some funfetti in the mixture and pipe some whipped cream on top for a fun “birthday” mug cake
This was delicious, really moist and flavoursome. Loved the texture.
This was great, thanks! An easy way to make a banana a little more exciting.
Great flavor but mushy.
I cooked for around 1 minute 30 seconds. I added a splash or two of oil instead of an egg. I would even use one and a half or two bananas! You could also substitute the sugar for rice malt or maple syrup, even half as much to make this healthier! Loved it, thank you!
This worked well as a quick snack!
I did put the egg in it and it made it rather eggy and dense. I’ll have to try it without the egg next time.
Made this today but made it dairy and soy free using earth balance “butter” and vanilla cashew milk. It was delicious. Next time I will try it with dairy free chocolate chips! Yum!
After dinner I love a sweet treat! This banana mug cake was delicious! I added another 30 seconds to get the perfect cake texture. I used almond milk and also Bob’s red mill gluten free flour. Definitely a 5/5!
Delicious! Make sure you use a large mug and put it on a plate before putting it in the microwave because this recipe makes quite a lot of batter. Great way to use up overripe bananas!
Quick, easy and yummy, added chocolate chips too! Cooking time was about 1 minute 30 for me though
Turned out great! Super easy and my son loved it. Total microwave time was closer to 1 minute 30 seconds.
The cake turned out really good!!! Great recipe!! Thanks
Am I doing this wrong? Is the consistancy supposed to be kind of jiggly not slightly crispy on the outside like most cakes? I just didnt know if that’s how mug cakes usually are or I am just doing something wrong. Great flavor though
It sounds like you’re doing it correctly. Unfortunately, mug cakes don’t tend to go crispy on the outside.
That was awesome. Thanks!
