Ingredients
Bananas
Ok, this wasn’t a surprise I take it? Banana mug cake recipes kind of need bananas. But guess what, they don’t need to be fresh.
This is a great recipe to use up those overripe bananas that have been hanging around in the fruit bowl all week. In fact, they’re the best ones to use as they will give a lovely sweet banana flavor.
Flour
I used plain flour for this recipe and added baking powder to give it a little lift as it cooked. As you know plain flour gives it more of a “sweet treat” feel. But healthier flours work too!
Dairy
Now that I’ve discussed the dry ingredients let’s have a look at the rest. Firstly, butter, then milk (any kind will do), and then an egg is needed (bonus protein points there!).
They all combine nicely to make a lovely cake batter.
Sweetness
I opted for maple syrup rather than the more refined sugar. Mostly because I enjoy that caramelly, woodsy flavor over the simple sugar.
There might be some minor health benefits to maple syrup, but in the end, it’s sugar, haha.
No maple syrup at hand? Just use sugar :thumbsup:
I used 1 teaspoon maple syrup, but you can increase this if you have a bit of a sweet tooth (just remember it will alter the nutritional information).
Toppings
There are literally loads of things you could pop on the top of your banana microwave mug cake.
Some ideas could be, raisins, Nutella (naughty), peanut butter, hazelnuts, almonds, coconut shavings, and grated dark chocolate. Whatever you fancy really – it’s also great on its own!

The egg will give you 6 grams of protein, it may not seem much but when trying to heal or gain new muscle, every bit of protein helps, and to gain a bit from a delicious mug cake at that is awesome!
And after all maple syrup contains a third of your daily intake of Manganese which is essential to healthy bones. If not much, it’s slightly “better” than plain sugar.
We should be aiming to keep our sugar intake low (6 teaspoons a day for women, 9 for men), and if this banana mug cake helps us do it, then all the better.

How to store and reheat a banana mug cake?
You can’t really store a mug cake, it’s best to eat after being cooked.
If you try and reheat a mug cake, you might find it dries it out so I would suggest eating it there and then before it needs reheating.
What to serve with banana mug cake?
A lovely spoonful of yogurt or scoop of ice cream would go really well on top of this delicious mug cake.
Can you make a mug cake ahead of time?
It’s probably best to make your mug cake when it’s ready to be eaten so it’s nice and fresh and warm.
Can you cook a mug cake in the oven?
Yes, actually if you don’t have a microwave, you can use an oven. I recommend preheating to 180 C / 360 F and baking for 20 minutes.
Is glass safe in the microwave?
Yes, glass is safe in the microwave as long as it is marked as ‘microwave-safe’, and the same goes for any ceramic mugs you use as well.
Why are mug cakes chewy?
There could be a couple of reasons why your cake is a bit rubbery or chewy, including overmixing the batter and overcooking the cake.
Luckily it takes minimal ingredients to make this mug recipe, so perhaps if you don’t get your first mug cake quite right, you can easily try again.

Recipe Variations
There are several different options for changing up this recipe,
- Different flours – One reader has tried this with spelt flour, and I think this is a great idea. Another option could be oat flour or almond flour.
- Different fillings – if you thought a banana mug cake sounded good, a banana chocolate mug cake sounds even better! Mixing in chocolate chips would really push up that sweetness level. Why not add extra fruit, like blueberries?

Top Tips!
- Use a very large mug and don’t overfill
- If the cake is leaning to one side, stop cooking, turn and continue cooking
- It’s easiest to mix all the ingredients in a separate bowl
- Cook shorter times rather than overcooking – an overcooked cake isn’t what you want – you can always give it another ten seconds when needed
- You may need to adjust your cook time depending on your microwave. I based this on my 1000w microwave, however, the best way to check is to do the toothpick test into the center of the cake, if it comes out clean it’s ready.
Thanks a ton for passing us this recipe, Cris! We’ll be asking you for many more, that’s for sure 😉

I’m not a foodie, although I do love eating. I believe food should serve us and our goals, not hinder. Taking control and responsibility for what I eat is important to me. Lots of veggie protein is my way forward.

Hello. Thank you for this recipe, I’ve made it several times now (standard version) & have altered it in various ways depending on its texture when all the ingredients are in. I make it in a glass measuring jug (it’s spacious & I can tell how cooked the cake is) & have found that my favourite version is banana, pear, oats & raisins (basically, I’ll add anything that will soak up excess moisture from over-ripe fruit!).
I’ll try adding nuts in the future, there’s some good suggestions here.
Hi Ellie! Your version sounds delicious too . And I fully agree about the more spacious jug, it really helps. Glad you like the recipe, and thanks for sharing your ideas!
Made this with coconut flour, coconut oil instead of butter or olive oil, coconut milk (extra to balance out the coconut flour dryness), an extra banana, shredded coconut, heaps of cinnamon and vanilla extract. Didn’t have any eggs or maple syrup on hand. and may have added too much baking powder (has an awesome bubbly texture almost like a crumpet! ) but it still turned out really well. Thank you
Awesome, Jin! I like the changes, bet it was delicious. I’m glad it turned out well for you, thanks for writing!
Hello, I just tried your banana mug cake recipe. It didn’t seem to want to cook for me. Twice I added an additional 25 seconds. I let it sit for 5 minutes and tasted it. It was still quite wet, almost doughy and reminded me more of bread pudding than cake. With that in mind I poured some cream over it and ate it like that. It was delicious! The next time I make it, I’ll add some raisins.
Hi Debra! Thanks for writing and I’m glad you enjoyed the cake in the end! I’m going to remake it myself over the next couple of days to check the cooking times and power and then report back here 🙂
Mine came out spongy and eggy. Was definitely a simple recipe though!
Hi everyone – a quick update. I made this again yesterday to check the cooking times and from my side, they were spot on. Using a less than 1000w microwave means they’ll need a bit longer than the stated time. If it tasted eggy I’d imagine it was one of two things – the egg was very large in comparison to the banana, or, simply that the egg wasn’t mixed in well enough. The banana really needs to get crushed up with the egg so it’s nearly smooth. It should cook well then 🙂
Could you use self-raising flour instead of separate plain flour and baking powder? If so, do you need more – or less – s-r flour than the recipe says, or the same amount?
Hi, I haven’t tried it with self-raising, but I absolutely don’t see why not 🙂 – that should be fine – and to use the same amount!
the best mug cake i’ve ever had, it tastes nice great with ginger too, it’s like a ginger cake
Cool addition, Megan!! Will deffo give it a go with ginger as well 🙂
Glad you liked that mug cake!
Wow! I just made this Banana Mug Cake & it came out Super-Dee-lish! (: Along with the original ingredients, I experimented & used 1 T. regular, organic sugar (instead of maple syrup) & I also added 1/8 t. cinnamon & 1/4 t. vanilla & some chopped walnuts into the batter. I nuked it in a heavy duty microwave safe, ceramic soup bowl & for my microwave, I cooked it for 2 mins 20 secs & it came out great! (: I’m going to be making this often & for guests! Thanks so much! (:
Made the vegan version and it was just sticky sludge 🙁
Are you able to clarify if it’s baking powder or baking soda? I used bicarbonate of soda as that’s meant to be the English name for the latter but then I’ve seen people say they used baking powder instead.
Hi Heidi! Oh dear, well a sticky sludge doesn’t sound ideal. Yes, I use baking soda for this one – but if it’s sludgy in the middle it sounds like it just needs a bit longer. I’ve found that results can vary wildly depending on microwave/oven – and even the size of the mug or bowl!
