This gooey banana mug cake is the perfect treat to cook when you are feeling a little hungry. It is a great, quick, and easy dessert that you can quickly cook as a late-night dessert.
By the time you are 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 that it is hard to resist making it every night. It only takes a few simple steps, a few ingredients, and a minute to cook. The result is a sweet, incredibly moist cake, the perfect treat for 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, 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 to serve 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, I would love to hear them.
Perfect Portion for One
A single serving of this banana cake will only feed one person unless you are not very hungry, in which case you might be able to feed two.
If you want to cook for two, 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 want to make a full dessert such as sticky date pudding.
Customize Your 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 chocolate chips to the cake mixture will give you a delicious cake similar to 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, leave the egg out. The cake should still cook to be gooey and moist. If the batter ends up a little too dry, simply add some more milk.
Additional spices, such as cinnamon or nutmeg, can help add even more flavor to the cake. If you want some nuts, slivered almonds or walnuts will work great.
Let us know if you enjoy any variations. I only touched on a few, and I know there are 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. Improperly mashed bananas leave you with a very unsatisfying cake as you won’t get the smoothness and sweetness that you require from the banana.
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 is incredibly easy but will need to be cooked in a traditional oven rather than the microwave.

Banana Mug Cake Recipe
Ingredients
- 1 Tbsp butter
- 1 egg
- 1 Tbsp milk
- 1 ripe banana, mashed
- 3 Tbsp all-purpose (plain) flour
- 2 Tbsp brown sugar (Amazon)
- ½ tsp baking powder
Instructions
- Place the butter in a microwave-safe mug and heat in the microwave until the butter has melted. 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
Recipe Tips
- If you like your mug cakes slightly gooey in the middle, 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. For example, gluten-free self-rising flour is the perfect replacement.
- Mug cakes can make a mess in your microwave, so keep an eye on them. Placing a plate under the mug will make cleaning up easier if it does overflow.
- 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 eggs.
- Avoid overcooking as it will likely turn the mug cake rubbery or hard.
Equipment I use
I use a 300ml (10 oz) microwavable mug (Amazon) for all the mug recipes that I have on this website. If you have a smaller mug, you may need to adjust the ingredients so it will not overflow.

Other Tasty Sweet Recipes to Try
There are quite a few easy desserts that you can cook in the mug. Personally, I think they are all good, but if you want a single-serve dessert similar to this one, be sure to check out the gooey chocolate brownie.
I love cooking mug cakes, as they are 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 bananas and is delicious.

Thanks! Hesitated because I’ve had bad banana mug cake before, but your recipe worked out perfectly. Sprinkled cinnamon sugar on top before it went in the microwave and was awesome!
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!
