All made in one bowl, with pantry staple ingredients, super quick to mix up, healthy, and SO DELICIOUS! Yes, that pretty much sums up this mini banana bread mug cake, and it’s the perfect individual little cake to bake up this weekend. With over-ripe bananas, good honey, and your favorite chocolate bar, this is sure to become your favorite banana bread in minutes. Perfect for breakfast, as an afternoon snack, or a late-night dessert.
When you’re looking for something sweet, but you still need something healthy and quick to bake up?
Make these cute little mug cakes.
Look, I’m well aware that a mug cake might not be all that exciting. But you guys, please hear me out. If you’re on the healthy January trend and you still want something sweet to enjoy on a Friday night or over the weekend, this is 100% your recipe. Typically I’m all about a real deal baked dessert. I tend to avoid microwaving anything, but I make an exception for a mug cake.
The inspiration? Well, it came from a few sources. First and foremost, my go-to banana bread recipe. I made it a few years back and it’s one of the handfuls of recipes I actually make on repeat. Of course, I love all the recipes I share with you guys, but because I’m cooking and baking so many new recipes day in and day out, I rarely find the time to come back to older recipes…no matter how delicious they are.
But this banana bread is different. I make it so often and so does everyone else in the family.
My second source came from the mug cakes I shared years and years ago that I brought back to life when everything went into lockdown. I’d forgotten what a fun and easy recipe they were. It’s actually a recipe I make on occasion every now and then when I just need something warm and sweet to enjoy, but I have no time to actually bake up a cake.
And finally, my third source of inspiration? No one other than my mom. She’s all about a low sugar, healthified dessert. And she loves nothing more than an EASY peasy recipe, so mug cakes just seemed fitting. With brown bananas on the counter and my favorite banana bread recipe in the back of my head, a banana bread mug cake was the obvious choice.
So, here we are, and the verdict? Better than I’d pictured in my head. The banana within these cakes is the real secret. Wel…the banana and all those chocolate chunks. Obviously.
The quick details.
This banana bread cake comes together in five minutes tops, so the details are pretty darn quick.
Start with your wet ingredients. I like to use coconut oil for these cakes. Melt it in the microwave in a microwave-safe bowl. Once melted, add a very overripe banana and give it a good mashing with a fork. The key to any sweet banana recipe is to use bananas that are way past their prime and pretty black all over. Black bananas create the best sweet recipes due to their natural amount of sweetness.
When you have the banana all mashed up, whisk in a squeeze of honey, a single egg, and a splash of vanilla. I personally like to use honey as my sweetener as I’ve found it creates a perfectly soft, tender, and moist banana bread cake. But maple syrup works well too.
Once the wet ingredients are combined. Stir in the flour, baking soda, a pinch of cinnamon, and a pinch of salt. At this point, the cake is almost ready for “baking”.
But I have a couple of secrets.
First, chocolate chunks…and a generous helping too. The chunks are a must and create the most luscious banana mug cake. You will fold them into the batter as the final ingredient. As the cake bakes, the chocolate sinks in, melting as it sinks. It leaves you with a puddle of warm melted chocolate throughout your cake. And with every bite, a little of that melted chocolate is scooped up.
And it is delicious.
Second, instead of mixing the batter in the mug you plan to “bake” in, mix the batter up in a small bowl, then transfer to a microwave-safe mug. Yes, it’s one additional dish to dirty. However, I found this ensures that the batter is more easily mixed up and in turn bakes up nicer too.
But the real KEY to success?
Eat this mug of banana bread warm, just after cooking. This isn’t a cake you want to eat leftover, it’s meant as a quick chocolate fix. It should be eaten right away and preferably with a small pat of butter, a drizzle of honey, and a sprinkling of sea salt on top. Nothing is better.
I will say that that every microwave is different, so the cooking time is a little tricky. That said, I tested this on two different microwaves and found two minutes to be just the right amount of time. You may need to adjust slightly by fifteen seconds, give or take.
Soo, have I convinced you that you need a banana bread mug cake in your life tonight?
This is the best afternoon pick me up…warm after-dinner dessert…or late-night treat while cozied up by the fire. It’s Friday, live a little. AND if you happen to have a snowy weekend in the forecast, you really need to bake this up. It’s great any day, but it’s best enjoyed on the coldest of days.

5 Minute Chocolate Chunk Banana Bread Mug Cake
Servings: 1 large mug
Calories Per Serving: 788 kcal
Nutritional information is only an estimate. The accuracy of the nutritional information for any recipe on this site is not guaranteed.
Ingredients
- 1 medium overly ripe banana, mashed (about 1/3 cup mashed)
- 1 tablespoon melted coconut oil (or butter)
- 1 tablespoon honey or maple
- 1 large egg
- 1 teaspoon vanilla extract
- 1/4 cup whole wheat pastry flour, or all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon ground cinnamon
- 1/4 teaspoon kosher salt
- 1/4 cup semi-sweet or dark chocolate chunks
Instructions
- 1. In a bowl, stir together the mashed bananas, coconut oil, honey, egg, and vanilla until combined. Add the flour, baking soda, cinnamon, and salt, mix until just combined. Fold in the chocolate chunks. 2. Pour the batter into a (10-12 ounce) microwave-safe mug. Microwave on full power for 1 minute and 35 seconds to 2 minutes (I always do 1 minute 35 seconds, but it's better to under "bake"). Eat warm with a smear of butter and a drizzle of honey (you should do this!). Enjoy!
Notes
To Oven Bake: Preheat the oven to 350 degrees F. Lightly grease a 2 cup oven safe ramekin/mug or 2 muffin tins. Add the batter and bake 22-25 minutes.
Microwave: every microwave is very different, so results may vary slightly. I have a 1200 watt microwave and found 2 minutes to be the perfect cooking time. You may need to cook 1 minute 45 seconds or 2 minutes 15 seconds. Start with 2 minutes.
i love helping my parents cook because they really dont like cooking very much
Awesome!!
oMg why is this so good without the guilt??? It’s so moist and decadent with the chips it gave me bread pudding vibes 🙂 I did microwave it for the full 2min just to make sure the bottom inner layer wasn’t soup-y
Hey Mariana,
Thanks so much for making this recipe, I am thrilled to hear it was enjoyed. Thanks for sharing your comment! xTieghan
very true mariana
My boys and I made this recipe and it was a HUGE hit. We have an egg allergy, so we subbed 1/4 cup of applesauce instead and it was delicious! They’ve literally asked to make it every day since, but we are out of bananas.
Hey Amy,
Thanks so much for making this recipe, I am thrilled to hear it was enjoyed. Thanks for sharing your comment! xTieghan
I didn’t have any chocolate so I added pecans and coconut, also divided it and baked half of it ( perfect portion for me). I think I’ll pick up a few chocolate chips in the bulk section and bake the remainder tomorrow. It was good but doubt I’ll put it into regular rotation. I think I’d rather make a couple pancakes instead if I have the urge.
Thanks so much for giving the recipe a try Gail! xT
In the instructions, you clearly say to cook in microwave for 1:35. But in your section about cooking in micro, you state yours is 1200W and you cook it for 2 minutes. I’m confused now.
Hey there,
In step 2, I state “Microwave on full power for 1 minute and 35 seconds to 2 minutes”. It all depends on your microwave. I hope you love the recipe! xTieghan
Easy and so delicious! The perfect way to use that last-past-its-prime banana! I followed your suggestions, even the honey on top out of the microwave oven!
Hi Liza,
Fantastic! I love to hear that this recipe was a winner, thanks so much for giving it a try! Have a great weekend:) xxT
I love your mug cakes but this one tasted so much like baking soda. Is 1/2 teaspoon really correct?
Hey Holly,
Yes, that is correct, you could try reducing that next time! I hope this helps! xTieghan
Yum! What a fun treat! I used almond flour and it turned out great!
Hi! So glad you posted as I would like to make a gluten free version. Did you use the same proportion of almond flour as all purpose flour? Thank you!
Yes, you can use an equal amount of GF flour, I am not sure how almond flour would work:)
Hey Susan- I used the same measurements! I’m new to almond flour but it turned out great!
Thanks!
Hi Mary,
Happy Friday!! Thanks a lot for giving this recipe a go, I love to hear that it was enjoyed! xxTieghan
what can we use as a substitute for eggs?
Hey there,
So sorry, I have never made this recipe without the eggs. Please let me know if you give the recipe a try, I hope you love it! xTieghan
We did 1/4 cup of applesauce instead of the egg and it was perfect!
I made this last night and LOVED it. It was absolutely delicious, great texture and not too sweet. As pointed out in prior posts, I’m hoping you can update the calorie estimation as it is way off. A quarter cup of semi-sweet chocolate chips alone is approximately 200 calories. I added up the ingredients and it is north of 500 calories, if the recipe makes one serving (I’m doing WW so a bit into tracking). Thank you, love your social posts and can’t wait to buy your new book.
Hey Ashley,
Happy Friday!! Thanks a lot for giving this recipe a go, I love to hear that it was enjoyed! Thanks for your feedback on the calories. xxTieghan
I love fun stuff like this when it helps move ripe bananas. This was a hit with everyone in my house. Bravo
Hi Rick,
Awesome!! Thanks a lot for trying this recipe out, I love to hear that it was enjoyed! xTieghan
How many servings does this make? Based on the calories, I am guessing 2? Can’t wait to make this!
Hi Anne,
This is for 1 serving. Please let me know if you give the recipe a try, I hope you love it! xTieghan
Looks good but do want to say I was all set to try it tomorrow for breakfast but after reading the comments about calories I’m taking a pass. 200 is perfect for breakfast but more than double that…yikes.
Sorry to hear this Cindy!
Loveeedddd this!
I made it last night with the butter and honey & oooofff it was delicious!
Definitely on my go to list now :).
Also, the banana I used wasn’t spotty, and it still worked out lovely! ?
Perhaps gave it better texture. Who knows, but it was divine!
Thanks for the recipe!
Hi Kaytee,
I really appreciate you giving the recipe a try, so glad to hear that it was enjoyed! Have a great week! xxT
Good idea but like others said it turned out gelatinous. Couldn’t finish it and won’t make again. Have really enjoyed some of your other recipes though!
Hi Adela,
So sorry to hear this, thanks for giving the recipe a try! xTieghan
