Summer is halfway over and it is still so hot here.  I am not a summer person.  I am much more chipper on a cold, snowy day that I am on a steamy beach day.  On steamy beach days you can find me inside, somewhere that has good air conditioning.

Even though itโ€™s crazy hot that doesnโ€™t stop my love of baking, so I felt a baking urge come on during one of the most sweltering days here. 

Our small window air conditioner was whirring away doing the best it could and I knew I couldnโ€™t tax it anymore or it just might give up and stop working.

This is when I’m so grateful for the microwave!

Banana bread mug cake

Summer is the perfect time to make a single-serve microwave treat.  In 90 seconds you can have a banana bread mug cake which you can enjoy in your air conditioned comfort.

I like homemade goodies way more than buying them, and this is faster than going to the closest store and buying something.  Way healthier too.  This microwave banana bread in a mug is gluten-free and high in protein!

Easy banana bread in a mug

In terms of easy banana bread recipes, you can’t get easier than this one.

You only need 3 or 4 ingredients, depending on if you use the chocolate chips.

I love this easy banana bread with the chocolate chips (because…chocolate), but sometimes I make it plain for my daughter since what 4-year-old really needs that extra energy boost from chocolate. Mine certainly doesn’t (“mama run!!!”, “mama run faster!!!”).

You need one bowl and a fork, and a couple of minutes in the microwave to make this easy banana bread. Perfect for first thing in the morning when you can barely think, a quick healthy snack after dinner, when it’s too hot to turn your oven on to make a full loaf of banana bread, and when you just want something that’s single serving without all those tempting leftovers around.

Microwave banana bread ingredients

You only need 4 ingredients to make this super quick microwave banana bread!

  • a banana (preettty essential for banana bread)
  • an egg (I like free range)
  • almond flour (or almond meal)
  • chocolate chips (any kind you like)

Cakes with no flour

You’ll notice in the above ingredient list, that there is no flour in this easy banana bread recipe.

We use almond flour or almond meal instead of regular all-purpose flour. This makes this microwave banana bread recipe gluten-free and paleo as well.

Even though it’s called almond “flour”, it is not a grain-based flour at all. Almond flour or almond meal is just ground almonds! Using ground almonds gives this banana mug cake a delicious, sweet taste, and adds a ton of protein too since there is more protein in ground almonds than regular wheat flour.

So, using almond flour makes this a banana cake with no flour!

Tips on making this microwave banana bread

This banana bread mug cake couldnโ€™t be any easier.  Four ingredients and 90 seconds in the microwave.  I made this three times in one week and Miss O loved hers too.  I gave myself more chocolate chips than I gave her, donโ€™t tell.

 

If you omit the chocolate chips, this recipe has only whole food ingredients and no added sugar โ€“ just sweetened with banana.  We ate this for breakfast, an afternoon snack, or an evening treat. 

The gluten-free-ness comes from using almond flour.  I love using this in baking so much.  It is ground almonds โ€“ thatโ€™s it.  It is full of protein and keeps your blood sugar more stable โ€“ no crashing like after a regular microwave muffin recipe.  This one is good, but it will work with any almond flour.

This recipe can make one thicker banana bread but I like the texture better when itโ€™s put into two dishes and cooked that way.  That way you can share one too!  If youโ€™re just making one, increase the microwave time by 30-60 seconds.  Still super fast!

Microwave banana cake

If you’re looking to fancy up this microwave banana bread recipe, you could add some fixins to make this easy banana bread more decadent.

I’m thinking chocolate frosting, cream cheese frosting, peanut butter chips, a melted chocolate drizzle…

Probably not all at once.

(Probably.)

We’re full-on in dessert territory here.

These additions would turn this recipe into a microwave banana cake recipe and would make an awesome smash cake for a baby’s first birthday!

I made something similar to this for Miss Os first birthday, with unsweetened real whipped cream on top – she loved it (and was surprisingly dainty about the “smash” part of smash cake).

Substitutions in this microwave banana bread recipe

A lot of people have tried this banana bread mug cake recipe (thank you guys!) and there have been different questions about substituting ingredients.

I wanted to add some info on subs for those who have asked.

You can’t sub the almond flour with coconut flour – coconut flour acts completely different in baking than almond flour and it won’t turn out.

You CAN sub the almond flour with regular white flour. It will have a different texture, will have less protein and fewer calories than the original banana mug cake recipe.

You can sub the almond flour with a gluten-free flour mix. If you use white flour or a gluten-free baking mix, the microwave time might be a little different. Just keep an eye on it while it’s baking into deliciousness in the microwave.

For the chocolate chips, you can sub dairy-free chocolate chips, vegan chocolate chips, white chocolate chips, peanut butter chocolate chips, etc.

If you want a lower carb version (the almond flour and egg are already low carb), you can use stevia-sweetened chocolate chips, monk fruit chocolate chips (I have wanted to try these!), or (gasp) leave them out completely.

I have tried to make a vegan version of this microwave banana bread but so far it hasn’t turned out super delicious so I haven’t shared it yet.

If you’re looking for a regular sized loaf of banana bread, try this paleo banana bread recipe – it is SO ridiculously good!!

Now, let’s make this healthy microwave banana bread mug cake!

Healthy single serving microwave banana bread

This banana bread mug cake is gluten-free and high in protein, AND it only takes 90 seconds in the microwave.

Course Breakfast, Dessert, Snack
Prep Time 1 minute
Cook Time 2 minutes
Total Time 3 minutes
Author Suchot Sunday

Ingredients

  • 1 egg free range
  • 1 banana
  • 3 tbsp almond flour
  • 1 tbsp chocolate chips

Instructions

  1. In a medium bowl, mash up the banana with a fork (or I use a pastry cutter like this).

  2. Crack the egg in this bowl and mix together.  Add the almond flour and stir.  Stir in half the chocolate chips.

  3. Pour the batter into a greased mug or small microwave-proof dish, or 2 small dishes.  Sprinkle the top with the remaining chocolate chips.

  4. Microwave on high for 90 seconds for shallower dishes and up to 2 1/2 minutes for a single deeper mug (like the brown one in the photos above!).  Stop at 90 seconds and see if it’s done.  If not, microwave at 30 second intervals (so it doesn’t overflow)

  5. Wait a minute or two before devouring this single serving banana bread (if you can!) because it will be pretty hot.ย  Enjoy!!

    I’ve made this recipe before but instead of chocolate chips I add cocoa powder or chocolate protein powder. It’s healthy and delish! My kids love it.
    I’ll be tweeting and pinning this. Greetings from the Inspire Me Monday linky!

  9. My 13YO is going to LOVE this! He’s a huge banana bread fan and being able to make it this quickly is going to mean he wants it every day. ๐Ÿ™‚ Thanks!

    1. Yay! I’m glad! I love single serving snacks for that reason – no wait time! There are many weeks where we make this healthy banana bread several times ๐Ÿ™‚

  10. Rebecca

    We don’t have a microwave, could we use a convection toast oven?

    1. Hi Rebecca! Yes you could use an oven instead. I haven’t made it myself that way but I would try 350 F for 15-20 minutes and check to make sure it’s set.

  13. Nicole

    Do you think you could substitute almond flour with coconut flour? If so, how much?

    1. No not in this recipe. Coconut flour acts totally differently than other flours. It absorbs liquids like a sponge. I’d like to make a coconut flour mug cake in the future! For now, if you can eat another kind of nut or seed flour, you can sub with that. You can grind your own pumpkin seeds or sunflower seeds if you can’t have nut flours.

    Can you just use gluten free flour?

    1. Ally, yes you can! It definitely won’t work with coconut flour, but an all-purpose GF flour will work. Sometimes I use the full 3 tbsp and sometimes only 2 tbsp if I use a gluten-free flour mix. It will have a different consistency than with the almond flour but will still be delicious.

        1. Yes! You can sub the almond flour with oat flour in this banana bread mug cake. Keep an eye on the cooking time, it might be slightly different! Hope you love it!! ๐Ÿ™‚

    Iโ€™m 11, and this was easy to make! My parents were impressed, it turned out really yummy! I used butterscotch instead of chocolate chips, and it was just as good! I have guilt when eating sweets, so this was amazingly good and healthy! Thank you!!!

    1. Thanks for your comment, it made me so happy! I’m glad you loved the banana bread mug cake and I love your addition of the butterscotch chips, yum! ๐Ÿ™‚

    My husband and I LOVE this recipe! Have you ever tried expanding it to make a full loaf? Or do you know what that would take? Thanks again for sharing!

    1. Yay, so happy you love the recipe! ๐Ÿ™‚ No, I haven’t tried making this banana bread recipe into a full loaf but that’s a good idea! I’d have to play around with it because it would take some major scaling from a mug cake. If you try scaling it up, let us know how it turns out for you. Have a great weekend!

    Can you use regular flour?

    1. Yes you can! I’ve made this banana bread mug cake with regular flour when that’s what I happen to have at home. I usually use the same amount, so 3 tablespoons. Sometimes it needs a bit more time in the microwave, just play around with it since every microwave is different. It’s delicious with regular flour too! ๐Ÿ™‚

    Thank you for sharing- it was very good & easy to make. Itโ€™s my โ€œdecoyโ€ dessert since Iโ€™m trying to cut back on sweets. I used pecans instead of chocolate chips. Next time, Iโ€™m adding in the chips:)

    1. Mmmm…I think pecans and chocolate chips together would be so delicious in this single serving banana bread!

    1. Hi Celeste! I’m not sure as I don’t count calories. You could always plug in the ingredients into an online calorie calculator if you’d like to check.

    This turned out great. I added a tbsp of chopped walnuts along with the choc chips. Tasted just like the loaf I usually make ๐Ÿ™‚

    Do you by any chance know the nutritional info on this per serving? Just looking calorie wise ? PleAse and thank you in advance

    1. I don’t know the exact nutritional info of this microwave mug cake, sorry! Somebody plugged it in to an online nutrition calculator and ballpark (I don’t remember exactly) it was around 300 or 350 calories. Hope you’re having a good day Nicole! ๐Ÿ™‚

  36. Bentley

    Hello. I’m 11 and I made this for my entire fam (6 people) and they loved it! Thank you for making this easy and yummy recipe! I memorized it by the time I made the 2nd one! So easy to make and worth it too!?

    1. Hey Bentley! So awesome that you made this recipe for your family! Glad you all loved it ๐Ÿ™‚ And who knows, maybe one day you’ll be a blogger sharing your recipes! ๐Ÿ™‚

  37. Becky Even

    has anyone replaced the egg with applesauce…I eat egg free????

    1. Hey Becky! I have tried to make a vegan version and so far I haven’t loved it/it hasn’t turned out well enough for me to share ๐Ÿ™ I’m going to keep trying different versions because I used to own a vegan bakery so I’m determined to get a super yummy vegan banana bread mug cake too!

    I added a few chopped pecan and vanilla extract to this, These added to the already great recipe,

  39. Pam

    Yum! To the original recipe I only added vanilla and an extra tablespoon of AP flour to my 3 of almond as it seemed too wet. Wish I had read comments first – I will definitely try cocoa and chocolate protein powder next time, and nuts !!

  40. Sue

    I used walnuts instead of chocolate chips. What is the calorie and carbs in this delicious little bread..

    1. Hi Sue! Thanks for trying this recipe. I don’t track calories or carbs and the nutrition info isn’t included with the recipe app I use for my site. You could plug in the ingredients into an online calculator if you’d like. I’m looking into changing recipe apps in the future to one that does include nutritional information. Have a wonderful day!

    Well maybe 4 tbsp of almond flour next time… mine never set up, came out kind of grainy. But I love the concept and itโ€™s so easy to throw together – I just mixed it all in the mug!

    1. I’m sorry it didn’t set up for you Steve! It’s sooo good when it does! There is always a bit of variation in different flours, egg size, etc so I hope you’ll try this microwave banana bread recipe again with the 4 tbsp almond flour. Thanks for stopping by! ๐Ÿ™‚

    Oh my gosh! This is absolutely amazing! I have made other mug cakes, but this just may be my new favorite – delicious!
