High Protein Banana Bread
High Protein Banana Bread with Chocolate Chips – This banana bread uses protein powder and skips the sugar for a nutritious and delicious breakfast treat or anytime snack with 17 grams of protein per slice! Plus, it’s lower carb and super satisfying!

Why We Love This High Protein Banana Bread
Banana bread is one of my all-time favorite comfort foods. It offers natural sweetness and fruity, earthy undertones. Plus, its moist-carby texture is so appealing. Add in some chocolate chips, chopped nuts, or other goodies, and whoo, I am a happy camper!
However, even though banana bread contains fresh fruit, it is not exactly health food. Today I’m sharing my favorite “Healthy” Chocolate Chip Banana Bread recipe made with protein powder… It’s leaning towards low carb, and can be made with your favorite sugar-free sweetener. It can also be made gluten-free, nut-free, and dairy-free as well.
Nutrition Notes
Please note, we are titling this recipe โProtein Banana Breadโ not a low-carb banana bread because bananas themselves are high carb. Even if all the other ingredients are low-carb there will still be carbs in this recipe. However, it does contain much fewer carbs than traditional banana bread, and is balanced out well with a boost of vanilla protein powder.
The exact protein ratio in each slice will be determined by the type of protein powder that you choose. You can use whey protein, or plant-based protein powder like soy protein, or pea protein from any brand. All of these vary in their protein contents, so our nutritional facts may vary as well, based on what you select.

Ingredients You Need
- All-purpose flour – for a lighter and fluffier crumb versus bread flour
- Vanilla-flavored protein powder – any variety you like (no vanilla extract needed!)
- Keto sweetener – like erythritol
- Butter – melted and slightly cooled
- Eggs – room temperature
- Bananas – very ripe, brown to black in color
- Milk – any type
- Baking powder – leavening agent to get that classic light spongey texture
- Salt – a pinch to balance the sweetness
- Unsweetened shredded coconut – optional, but adds a great texture and lightly nutty sweet taste
- Chocolate chips – optional, your choice of regular or keto chips
How to Make Protein Banana Loaf
- Preheat the oven to 350ยฐF. Set out a standard 5×9-inch loaf pan. Grease the bottom and sides of the pan well and set aside.
- Set out a large stand mixer, or a large mixing bowl and hand mixer. Combine the keto sweetener, melted butter, and eggs in the mixer. Beat until well combined. Then peel the bananas and add the overly ripe fruit to the mixture. Beat again until mostly smooth.
- Scrape the bowl with a rubber spatula, then turn the mixer on low. Beat in the milk, baking powder, and salt.
- Then slowly add in the dry ingredients: flour and protein powder, a little at a time. Once the mixture is smooth, scrape the bowl with a rubber spatula.
- Then turn on low, once again, and stir in the shredded coconut, and ยฝ cup of chocolate chips. *Reserve 2-4 tablespoons of chocolate chips to sprinkle over the top of the bread.
- Scoop the high protein banana bread batter into the prepared pan, smoothing it into an even layer if needed. Sprinkle the remaining chocolate chips over the top.
- Bake in the center of the oven for 40 minutes. Then cover the top loosely with a piece of foil and continue to bake for another 15 to 20 minutes. *The foil protects the top from turning too dark.
- The banana bread is done when a toothpick inserted deep into the center of the bread comes out clean. Carefully run a knife around the edges of the pan to loosen the sides.
- Then allow the banana bread to cool in the pan for another 10 to 15 minutes before flipping it out onto a cooling rack.
Pro Tip: You can serve banana bread right away, but it cuts better when it is allowed to cool all the way to room temperature.

Recipe Variations
- Gluten-free – Swap all-purpose flour with your favorite GF-friendly alternative. Oat flour will also work.
- Dairy-free – Use a plant-based butter substitute and nut milk like almond or soy.
- Vegan – Use plant-based swaps for the butter and milk, then use vegan egg substitute.
- Protein powder – Choose any type you like, made with your preference of protein (like soy, pea, or whey protein powder) in vanilla or cinnamon flavor.
- Sweetener – Depending on dietary preferences you can use keto-friendly erythritol, maple syrup, coconut sugar, or regular cane sugar if you like.
- Protein banana bread add-ins – In place of or in addition to milk or dark chocolate chips and coconut you can try other goodies like peanut butter or white chocolate chips, chopped walnuts or pecans, or dried fruits.

Frequently Asked Questions
I love to smear a soft pat of butter on a warm slice of banana bread. Or add a dollop of peanut butter, almond butter, or your favorite nut butter!
Typically no. Banana bread is one of those classic not-so-healthy morning items like breakfast pastries and muffins… Sure, they give you a nice burst of energy and, yes, are healthier than other baked goods like cookies and cakes. However, like all things that contain sugar (or alternative), this healthy chocolate chip banana bread should be enjoyed in moderation.
Wrap the loaf tightly in plastic wrap, or place it in a freezer bag that’s sealed with all of the air squeezed out. Keep on the counter at room temperature for up to 5 days. For longer storage, you can keep the bread in the fridge and it will last for up to a week or two.
Yes, this is a great recipe for baking and freezing! After the baked loaves have cooled completely, wrap them tight in plastic wrap and then in a layer of aluminum foil. Or place it in an airtight container. Store in the freezer for up to 3 months.
