Microwaveable Double Chocolate Banana Bread: High Protein Snack

This post may contain affiliate links. Click here to read my full disclosure.

One of my favorite things in the world is seeing one of my recipes in the wild. When someone takes the time to share a recipe re-creation, it always puts a smile on my face. Not only do I get valuable feedback and ideas for potential tweaks or substitutions, it lets me know that my recipes are actually helping people make better dietary choices. If I had to pinpoint one recipe that’s been recreated the most, it would easily be the one-minute, 100-calorie protein brownie.

Folks love those things! And it makes sense. Even if you double the recipe, you have a delicious, high protein snack that’s ready in a few minutes. Ya can’t beat it. Just take a look at the video below to see how easy it is to make this protein banana bread.

I don’t know why it’s taken me so long, but I’ve recently jumped back in to make even more microwaveable protein brownies and desserts like this double chocolate high protein banana bread. I’ve taken the liberty to double the recipe from the get go, so the calories are a bit higher than the perfectly titled 100-calorie protein brownie. Nonetheless, I was sure to leave notes on how you can make the recipe even lower calorie.

Ingredients for Double Chocolate High Protein Banana Bread

You’ll find this recipe has a very short ingredient list, just how I like it. The only ingredient notes I have for you here are on the fat source and the optional sweetener.

If you’re familiar with my recipes, you know I typically recommend stevia as a zero-calorie sweetener option. I still love stevia and use it regularly, but I understand that some don’t enjoy the taste. So, I’ve been experimenting with other low-calorie sweeteners and have fallen in love with Swerve’s confectioners blend.

Swerve is a sweetener that subs 1:1 for sugar and is made from erythritol and oligosaccharides (similar to the IMO syrup I used for the homemade quest bars). If you don’t have an issue with artificial sweeteners, I would highly suggest picking some of this up. So far, I’ve found it works a bit better in baked recipes than stevia. I got mine on Amazon here.

And yes, I’m using the confectioners blend. Since I rarely use large amounts of a sugar replacement, I wanted to kill two birds with one stone and be able to use Swerve for both baking and icings/frostings. If you’re going to be using larger amounts of Swerve, like in full-sized cakes, you’ll probably want to get the granular version.

Outside of the sweeteners, the only other thing I’ll add is that I’m convinced you can swap apple sauce for canned pumpkin and vice versa in any of my microwaveable protein recipes with very minimal texture differences. One obviously is a bit sweeter and has a mild apple taste, but I really can’t tell the difference otherwise. If you can’t find one or the other, or you just want to play around with both, do ya thang.

Making This High Protein Banana Bread in Bulk

If you’ve seen my recipe for make-ahead one-minute protein brownies, you could use the same strategy here. Since we’ll be using bananas, you’ll want to use any stored banana bread jars within 3 days or so. You could also freeze them and thaw before cooking or even pre-mix everything except the banana ahead of time.


You can use any protein you’d like, but I usually go with Optimum Nutrition Gold Standard Whey and/or Dymatize’s Whey or Elite XT blended protein. They’re reputable brands that have been around forever.

The macros in both recipes are with Gold Standard Whey.

HOW TO Make Moist Desserts with Protein Powder Every Time

Since there are a lot of moving parts in recipes with protein powder (different types of protein, volume differences in scoops, scooping vs weighing accuracy, etc.), there’s always a chance you’ll end up with a tough or dry finished product. I’ll include a few ideas to combat this below:

  • Use whey concentrate or a blend of proteins that’s not super lean like whey isolate (the extra carbs/fat goes a long way)
  • Slightly reduce the amount of protein powder used
  • Increase fat sources or faux fat sources (i.e. pumpkin, mashed bananas, sweet potato, avocado, unsweetened apple sauce, coconut oil or processed coconut flakes, etc.)
  • 14 grams of light butter only has 50 calories and changes lives
  • Slightly increase liquid ingredients
  • Reduce cook time
  • Add moisture after cooking via whipped topping, ice cream, or fruit reductions

In the case of this high protein banana bread, you’re already using two faux fat sources in mashed banana and apple sauce. Unless you’re using a terribly unfriendly protein powder or stray from the recipe, this banana bread should be moist. That said, you can always make adjustments as needed. Ain’t nobody got time for dry or tough protein treats.

  • 1 scoop (32g) Protein Powder vanilla
  • 1 Tbsp (5g) Unsweetened Dark Cocoa

  1. Mix ingredients in a bowl and microwave for 90-120 seconds. Don't overcook. (The center may still be a bit gooey.)

  2. Depending on the size of your bowl, you may have to finish the last 30-60 seconds in 10-15 second intervals to avoid overflow.

  3. If your brownie sticks to the bowl, you may try mixing the brownie in a bowl and transferring the batter to a separate bowl you've sprayed with nonstick cooking spray before going in the microwave.

  4. Top with low-calorie ice cream, fat-free whipped topping, or other toppings of your choice.
