If you’re a fan of banana bread, you’re going to love this high protein banana bread recipe. As the title implies, it’s microwavable and super simple. You’ll need five ingredients max, and the cook time is just as short. Not to mention, one mini loaf, mug cake, or whatever you want to call it contains 27 grams of protein.
Before you get to the recipe, I’ll quickly add that I’m mad for microwavable protein desserts and sweets. If you enjoy this banana bread and want to try my other recipes, I’ll link a handful of my favorites below.

Check out this clip of the double chocolate banana bread to get an idea of how this recipe is. You’ll also see that I use a separate bowl for mixing, which can make your finished product a bit prettier.
If you’re going to be making more of my microwavable protein treats, I can’t recommend the white bowls you see in the clip above. You can check them out, and every other product or tool I use, on my Amazon list.

I was sceptical about this as it seemed too easy and too good to be true. I was sooo wrong! It was dead easy indeed, and fabulously tasty. I only replaced the walnuts with berries (just to save a few calories, but otherwise the walnuts go better with the banana flavour). Thank you for this recipe, loved it!
Happy to hear you enjoyed it! And I love the berry swap idea. Thanks for the feedback.
This is my go-to banana bread recipe now (minus the walnuts due to allergies). I suggest to get a little daring and throw some chocolate chunks in there… I promise you won’t be disappointed.

One of my favorite protein desserts! I make this every couple weeks and it’s perfect every time. Great with ice cream if you can spare the macros. I normally put the walnuts in the batter rather than on top. So tasty!

I was very skeptical as recipe seems to be missing ingredients – I kept looking for evidence of egg left out of ingredients. I had to cook it way longer than 90 seconds, even with a powerful microwave. I lost track of time but it was at least 3X as long before it looked cooked. I did not weigh my banana so I am wondering if maybe it was too large. I did add 1/2 TBSP SF chocolate chips. I did add the walnuts and the SF syrup on top after cooking. It tastes delicious!
