Not only is this whole loaf packed with 130 grams of protein (which is about 13 grams per slice), but it’s so quick and easy to whip up. We’re using a blend of oat flour and almond flour for this loaf, resulting in a perfectly soft and fluffy texture that is guaranteed to be hit!

Ingredients Needed
- oat flour – you can make your own oat flour if you’d like or use store-bought. I like Bob’s Red Mill oat flour.
- almond flour – make sure you get almond flour and not almond meal! Bob’s Red Mill almond flour is what I typically buy.
- vanilla protein powder – the main source of protein in this protein banana bread. Your favorite brand of vanilla protein powder works, but Nuzest is one of my favorite brands. It’s plant-based and has a minimal, clean ingredient list. Plus, the vanilla flavor is delish. You can use my code eatingbirdfood for 15% off your order.
- ripe bananas – the star of the show adding moistness and natural sweetness. Make sure you’re using ripe bananas that have brown spots for the best results.
- Greek yogurt – the secret ingredient for a moist texture without the need of added oil. Plus, it adds some more protein to this loaf. I used full fat Greek yogurt, but 2% will also work. I don’t recommend using fat-free yogurt as it has added ingredients that can change the consistency of this banana bread.
- maple syrup – the perfect natural sweetener for this recipe! I love the flavor the maple syrup adds to this loaf. Make sure you’re using pure maple syrup and not pancake syrup as that’s loaded with corn syrup and additives.
- eggs – helps bind all the ingredients together and provide structure for the banana bread.
- chocolate chips – I really like Lily’s chocolate chips because they’re dairy-free, lower in sugar and still have a great flavor. I also like the Enjoy Life dark chocolate chips which are vegan + allergen-friendly.

Substitutions & Notes
- Chocolate protein banana bread: Want some extra chocolatey goodness? Swap the vanilla protein powder with chocolate protein powder!
- Flour: This recipe hasn’t been tested with different flour so I don’t recommend substituting the oat or almond flour with another flour.
- Protein powder: This loaf hasn’t been tested with anything besides protein powder, so I don’t know what a good substitute would be. If you’re looking for a chocolate chip banana bread recipe that doesn’t call for protein powder, I suggest making my almond flour banana bread or chocolate chip coconut flour banana bread instead.
- Eggs: I haven’t tried this loaf with an egg substitute like flax eggs, but if you end up trying it let me know in the comments below!
- Greek yogurt: To make this loaf dairy-free swap the Greek yogurt with a dairy-free yogurt of choice.
- Maple syrup: You can swap the maple syrup with honey or another liquid sweetener like agave or monk fruit maple syrup. I wouldn’t recommend subbing the maple for a dry sugar like coconut sugar or cane sugar as I haven’t tested it and that would likely affect the overall texture of this loaf.
- Chocolate: Feel free to skip the chocolate chips or substitute it with a different mix-in of choice like chopped nuts (pecans, walnuts or almonds would all work well) or dried fruit.
How to Make
Step 1: Preheat your oven to 350°F and prepare your loaf pan with parchment paper or cooking spray. In a medium bowl, mix the oat flour, almond flour, protein powder, baking soda, baking powder, and salt.
Step 2: In a large bowl, whisk together Greek yogurt, maple syrup, mashed bananas, eggs, and vanilla extract until smooth.
Step 3: Add the dry ingredients to the wet ingredients and mix until just combined. Gently fold in the chocolate chips.
Step 4: Pour the batter into your loaf pan, add extra chocolate chips if desired, and bake for 55-65 minutes, covering with foil if needed. Let the bread cool in the pan before transferring it to a wire rack to cool completely.
Recipe Tips
- Transfer to a cooling rack: Once done cooking let the bread cool for about 10 minutes in the pan and then remove to cool completely on a wire rack. Don’t leave the bread in the pan for too long because it’ll continue to bake and could dry out or start to condensate.
- Use ripe bananas: Make sure you’re using ripe bananas with brown spots on them for the mashed bananas that are being mixed into the batter. The older, browner and mushier, the better! Here are some different ways to quickly ripen bananas if your bananas aren’t ripe enough.
- Cover if needed: Make sure to check your bread around the 30-minute mark in case your loaf is browning quickly. If so, I recommend covering the bread with tin foil so it doesn’t get too brown.
- Test for doneness: To check if your banana bread is fully baked, insert a toothpick or a knife into the center of the loaf. If it comes out clean or with a few moist crumbs, your bread is ready. If there’s wet batter on the toothpick, bake for a few more minutes and check again.
How to Store
Store this banana bread in an airtight container on the counter for about 2-3 days or in the fridge for about 1 week.
For longer storage, you can store this banana bread in the freezer for up to 3 months! You can freeze the full loaf or individual slices for easy serving when you’re ready to thaw and enjoy. To thaw, place bread in the fridge overnight, at room temperature or defrost in the microwave or toaster oven.
Frequently Asked Questions
I recommend using a plant-based protein powder with minimal ingredients. I used Nuzest vanilla protein powder but I also love the Sun Warrior Vanilla Warrior Blend protein powder. Both don’t have a chalky taste and the ingredient list is minimal. You really can’t taste the protein powder in this banana bread at all and they have a great texture!
This loaf makes 10 slices and one slice of banana bread has about 13 grams of protein. The amount of protein will of course depend on the type of protein powder and yogurt you use as well as how big or small your slices are. If you want to add even more protein to this recipe swap the chocolate chips for chopped nuts instead.

Protein Banana Bread
Ingredients
- 1 cup oat flour
- 1 cup almond flour
- ½ cup vanilla protein powder, I used Nuzest
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- ½ teaspoon sea salt
- ½ cup full fat Greek yogurt
- ½ cup maple syrup
- 1 cup mashed ripe bananas, 3 medium bananas
- 2 large eggs
- 1 teaspoon vanilla
- ⅔ cup chocolate chips, plus more for topping
Instructions
- Preheat oven to 350°F and line a loaf pan with parchment or spray with cooking spray.
- In a large mixing bowl, mix together the dry ingredients: oat flour, almond flour, protein powder, baking soda, baking powder and sea salt.
- In a separate mixing bowl, whisk together the wet ingredients: Greek yogurt, maple syrup, bananas, eggs and vanilla extract.
- Pour the dry ingredients into the wet ingredients and stir until just combined.
- Fold in chocolate chips.
- Pour the batter into prepared loaf pan. Top with additional chocolate chips.
- Bake for 55-65 minutes, or until a toothpick inserted into the center comes out mostly clean. It’s okay if it doesn’t come out fully clean as the bread will continue to bake in pan. Check at 30 minutes and cover with tin foil to help the top from browning too much, if needed.
Notes
- Storage: Store banana bread in an airtight container for 2-3 days at room temperature or up to 1 week in the fridge. For longer storage, freeze for up to 3 months, either as a whole loaf or in individual slices. Thaw in the fridge, at room temperature, or quickly defrost in the microwave or toaster oven.

I’ve made this twice in 3 days and it’s already gone again! Definitely our new favorite banana bread recipe. It doesn’t even taste gluten free. Sooooo good! Recommending it to everyone!
YUM! So happy to hear you found this recipe and are loving it, Carina. Thanks for sharing your review & star rating, means so much to me!
Fantastic and I have tried a lot of recipes! For those asking, I substituted oat for almond (100% oat) due to allergy and it turned out perfect. These flours have similar moisture content. Also I cut back a little on the syrup and still plenty sweet. Kids love them!
WOO! I am so glad you and the family are loving this recipe, Joanne. Thank you so much for sharing your review & star rating, it means so much to me!
So good! I added pecans last weekend but thinking about walnuts next time. My husband, who doesn’t care for bananas, asked when I’m making this again. Thanks Brittany!
YUM! I am glad to hear this recipe is a hit, Caroline. I bet this would be amazing with walnuts too. Thank you for coming back and sharing your review + star rating, I really appreciate it!
I made this last night into 4 mini loaves (using my mini loaf Wilton pan). They turned out great! I used half the honey, only added some chocolate chips to 2 of the loaves only on top (for the kids). The plain ones are absolutely delicious and even my husband said they are plenty sweet.
YAY! I am so excited to hear that you are loving this recipe and it turned out great using the mini loaves. Thanks so much for coming back and sharing your review + star rating, I really appreciate it!
Can you use the vital proteins unflavored collagen protein?
Hi Melissa – This loaf hasn’t been tested with anything besides protein powder, so I don’t know how the collagen would work. If you give it a try, let me know how it turns out for you!
Hi Brittany, my son is allergic to nuts (specifically almonds but most anyway). Is there an alternative to the almond flour that keeps the recipe’s nutrient value similar (grams of protein and calories, etc)?
Thanks, Cindy
Hi Cindy – This recipe hasn’t been tested with different flour so unfortunately I cannot recommend another flour for this recipe. So sorry!
As I made these I was super skeptical thinking that I would for sure notice the protein powder aftertaste… but NO! These taste just like high sugar, not healthy banana bread and yet gives my teen athlete the protein boost she needs after school without a sugar crash. Brilliant. Will be making many more of your recipes!
WOO! This is so great, Andrea. I am so glad you gave this recipe a try and are loving it. THanks so much for sharing your review + star rating, I truly appreciate it!
Hi there,
Would it work to sub out the almond flour for more oat flour?
Hi Rachel – This recipe hasn’t been test any other way, so I wouldn’t recommend subbing out the flours. So sorry!
Very tasty-I did muffins as well & used a salted pb protein-I ate 2😬 definately a keeper ! Thanks
Amazing! I am so glad you gave these a try and the muffins turned out great for you. Thanks so much for your review & star rating, I truly appreciate it!
This was fantastic as muffins (350 x 20 min). I accidentally left out the maple syrup (but still had the choc chips) and they still tasted amazing. You couldn’t tell that i had left out the sweetener. Also fantastic texture which is NOT a given with gluten free recipes. Definitely going to be making this often. Thank you!
YUM! I am SO glad you gave these a try and they turned out amazing for you as muffins. Thank you so much for sharing your review & star rating, I really appreciate it!
