I am a fan of banana bread and a fan of protein and this protein-packed banana bread checks all the boxes. This bread is fluffy, moist and perfectly sweet despite being made with no added sugar, whole wheat flour, and the addition of protein powder. It tastes just like banana bread but has a whopping 13 grams of protein per slice.

This moist banana bread has a traditional banana bread taste but is made with whole wheat flour, non-fat Greek yogurt, and vanilla whey protein powder to making a perfect way to up your protein intake. It is free of any added sugar and sweetened with applesauce, honey and ripe bananas to make it low in fat and calories.

I promise you, this banana bread is every bit as satisfying and delicious as the real deal and the perfect healthy snack. Try it, you won’t be sorry! If you’re looking for protein powder free, try my Greek Yogurt Banana Bread with Chocolate Chips.

Why you’ll love this recipe

  • Less than 150 calories and 13 grams of protein per slice with no added sugar.
  • Perfect use of those overripe bananas.
  • Can add chocolate chips, walnuts or blueberries for flavor.

Ingredients and Substitutes:

These are the main ingredients and substitutions. See the recipe card below for the full ingredients list and instructions for this protein banana bread.

Ingredients for protein banana bread, including applesauce, Greek yogurt, and vanilla protein powder.

Bananas: the most important ingredient! For best results, make sure to use overripe bananas. It sweetens the bread and mashes well. I like mashing the banana on a cutting board prior to adding to the bowl vs. trying to mash along the side of the bowl. 

Greek yogurt: I used plain non-fat Fage but any plain yogurt will work.  Use dairy-free alternatives if desired. This may result in a different texture.

Applesauce: make sure it’s unsweetened to avoid adding refined sugar. 1/4 a cup is almost (not quite) a single pack of sauce so I like to buy the cups so I don’t waste. 

Honey: can also use sugar substitutes like Stevia for even fewer calories.

Flour: I use whole wheat flour. You can substitute with all-purpose flour at 1:1 ratio or with oat flour at 1 cup: 1 1/3 cup ratio. I prefer whole wheat in this.

Protein Powder: this recipe is best Gold Standard Whey Vanilla Ice Cream or PEScience. You can substitute a whey-based protein powder for a similar same texture.

Optional add-ins: dark chocolate chips, walnuts or blueberries.

Variations

  • For a salty nutty crunch add in 1/2 cup of chopped walnuts.
  • To make this a little more decadent and rich, add in dark chocolate chips and top with maple syrup.
  • If you want something low calorie but to sweeten it up a bit, add 1/2 cup of frozen blueberries (fresh works too) so the juices go into the bread as it bakes.
  • Drizzle nut butter on top like peanut butter or almond butter.

Dietary Modifications

  • To make gluten-free, use Bob’s Red Mill GF 1:1.
  • Use flax eggs as needed.

How to make Protein Banana Bread

Step 1: preheat and prep

Preheat your oven to 350 degrees Fahrenheit and prepare a loaf pan with non-stick cooking spray or line it with parchment paper.

Step 2: mix wet ingredients

All wet ingredients for banana bread in a large mixing bowl.

In a large bowl, combine the mashed bananas, Greek yogurt, applesauce, honey (or sugar substitute), eggs, and vanilla extract (image 1).

Fully combined wet ingredients for banana bread in a large bowl.

Mix until fully combined (image 2).

Step 3: mix dry ingredients

In a separate bowl, combine the whole wheat flour, protein powder, baking powder, baking soda, salt, and cinnamon (image 3). Whisk to combine.

Dry ingredients fully combined in a bowl.

Step 4: combine ingredients

Dry ingredients gradually added to the wet.

Gradually add the dry ingredients to the wet ingredients (image 4).

Banana bread batter mixed and ready to pour.

Add and mix until just combined (image 5). If using, fold in the chopped walnuts, dark chocolate chips or blueberries.

Step 5: pour the batter

Pour the batter into the prepared loaf pan, smoothing the top with a spatula (image 6). Bake for 50-60 minutes (more if needed), or until a toothpick inserted into the center comes out clean or with a few moist crumbs. If the top is browning too quickly, you can cover the bread with a piece of aluminum foil.

Step 6: cool and serve

Allow the banana bread to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.

Expert Tip!

No ripe bananas? No problem. Using a fork poke holes in the banana peels and microwave for 30-second intervals until desired softness. I have done this many times and it works great!

Recipe FAQs

Can I omit the protein powder?

I’d instead make my greek yogurt banana bread. It’s very similar to this recipe without protein powder.

Can I add chocolate chips and walnuts to banana bread?

Add whatever you want! I love chocolate chips, walnuts, pecans and even drizzling peanut butter between layers of batter.

What is the serving size of protein banana bread?

Slice into 10 equal slices at about 75g per slice. The nutrition info is an estimate and does not reflect any optional add-ins or substitutions.

How should I store leftover banana bread?

Store your protein banana bread in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.

Can I use other flavors of protein powder?

Sure! Use chocolate protein powder for a chocolatey version. Just be sure to use one you love the flavor of because it will directly affect the taste. This has not been tested with plant-based protein powder or vegan protein powder. 

Can I use almond or coconut flour?

This recipe has not been tested with almond flour or coconut flour which will result in a very different bread than this recipe.

    I followed this recipe exactly except I subbed gluten free flour. I’ve never had a problem with other recipes doing this. I could tell after mixing the batter that it was way too liquidy. My chocolate chips all sank to the bottom and my edges are way too crisp:/ still tastes okay but not sure what happened with the liquids. Any recommendations for making this gluten free if the whole wheat flour really matters that much?

    Great recipe. I made with unflavored whey isolate protein powder and added a few drops of liquid stevia to make up for the lack of added sweetness from vanilla protein powder. Also made into muffins because I halved the recipe based on the amount of bananas I had (so I knew it wouldn’t fill a loaf pan well). Less cook time was required, as you’d expect. The end result was not overly sweet (I like this!). They were also surprisingly light/fluffy – they don’t look dense like the photos from the original recipe but I’m guessing that’s due to the protein powder I used. Especially delicious when served warm. Will be making this again!

    I used reg self rising flour, didn’t add baking soda or powder, and used plant based protein powder. Came out great!! Also baked in muffin tins and only had to bake for 20 mins! Made 12 muffins and had batter left for probably 10 more. Not as sweet as I am used to for banana bread but that’s expected because it’s healthy! Still yummy!

    The banana bread turned out great. It was fluffy but still moist and had a very good taste, thank you Danielle!

    I had some frozen bananas laying around in the freezer. Fortunately after thawed it’s 400 g. Two substitutions were made; coconut milk in place of applesauce, and chocolate mint whey protein in place of vanilla protein. The batter was in the sweet spot between being dense and fluffy. I made two mistakes, not using parchment paper nor a silicone loaf pan. It got stuck in the pan. It came out perfect for pre-workout or late night cravings. Thanks God all these flavours merged into something delicious.
    Thank you 😊 🙏🏼

    Followed the instructions to a T and the inside never cooked! I left it in there for 90 mins and the outside just got more and more brown and the inside stayed raw. Had to throw it out 🙁

    1. Oh no, what a bummer!! Covering with foil helps to keep it from browning faster than baking but I’ve had people in the comments have to reduce the recommended bake time for their oven so it sounds to me like our ovens vary quite a bit because mine would be way overcooked after 90 minutes.

  7. Hi! Can I use regular unflavored protein powder? If so what changes would need to be made to the recipe? It looks delicious honestly!!!

    1. Vanilla adds a TON of flavor and sweetness so it would change it a lot using unflavored.

    Made this yesterday (used PE Science’s Cake Pop protein powder). Added chocolate chips to the top before baking. It was SO good. Even my 11 year old, who had a friend over, wanted to try it. When I told him it was “protein banana bread” he rolled his eyes at me 😂 and said “I probably won’t like it”. Yeah. He and his friend each ended up eating a full slice LOL. I’ll be making this regularly, I’m sure!!

    I just made this. It turned out perfect. The top did brown a little, but didn’t taste burnt. I didn’t use the tinfoil method either.
    The banana bread came out juicy and not dry.
    Ps: I love how the grams are shown.

    This recipe was ok but not great. I made exactly as instructed in the recipe – the outside was burned (I used foil), the inside was kind of dry, and all the chocolate chips and nuts sank to the bottom. It barely tasted like bananas. It was edible but not enjoyable to eat.

    I have attempted this recipe twice using gluten free flour and collagen protein powder and both times it is pure mush in the center. I baked it 30 mins longer than suggested and the center is still not done. The second time I even increased the protein powder to absorb more of the liquid/moisture but the result was still mush. It does not hold shape. It collapses once taken out of the oven.
    Lots of wasted time and expensive ingredients.

    1. You are using two ingredients the recipe doesn’t call for. This bread is made with whole wheat flour and whey protein powder. Collagen protein powder will bake completely different than a whey protein powder. Changing the ingredients that drastically is bound to have a completely different outcome than the written recipe.

      1. My thoughts exactly. If you don’t follow the recipe and it doesn’t turn out, that’s not because there’s a problem with the recipe.

    Love this higher protein alternative! Grandmas recipe isn’t the healthiest 😂 so for times I want lower calorie, higher protein option this is perfect. Husband and toddler approved too!

    1. 5 stars
      Turned out delicious! Thank you! Hubby loved it! I use vanilla premier protein powder, regular flour and butter in place of the applesauce with Greek God Honey and Vanilla Greek yogurt.
