Adding protein powder to desserts and baked goods is one of my favorite things to do. As someone who follows a muscle-building diet, knowing that my treats are aiding my muscle growth keeps me motivated towards my goals.

Some of my favorite treats to add protein to include cookies, muffins, and donuts. To change things up, I wanted to throw banana bread into the mix!

Can I add protein powder to banana bread?

Adding protein powder to any old recipe is not recommended. Protein powder transforms the structure of banana bread, so we need special ingredients to compensate. Luckily, we’ve created the best of both worlds, which is why this protein banana bread recipe is such a winner!

Why you’ll love this recipe

  • It’s moist and fluffy with a tender crumb. Just like any good banana bread out there, this protein-rich one tastes exactly as what you’d expect it to, except with a protein boost.
  • It’s made in just one bowl, meaning there is NO clean up required…or messy dishes to wash up.
  • Each slice packs in over 18 grams of protein, so you’ll feel fuller for longer!
  • There are no eggs or dairy needed, so those who follow a vegan diet can definitely enjoy a slice or two.

What I love about this recipe is that it’s healthy enough to eat for breakfast, a wholesome snack between meals! Heck, I love to add a scoop of protein ice cream on top and enjoy it as a protein-packed dessert!

How to make protein banana bread?

The Ingredients.

  • Bananas– Overripe bananas are a must, as they will make the bread extra moist and extra sweet. 
  • Milk of choice– I used unsweetened almond milk, but any milk will work. 
  • Vinegar– White or apple cider. This reacts with the self rising flour to give the bread some rise and fluffiness.
  • Vanilla extract– A must for any good banana bread. 
  • Self rising flour– Skip the expensive pre-made blends and make your own
  • Almond flourBlanched or superfine almond flour, not almond meal. 
  • Protein powder– I like using a vanilla flavored protein powder, but unflavored works. Brown rice protein powder or casein protein powder are the best protein blends for baking. 
  • Sugar or alternative– White, brown, or coconut sugar, or sugar free alternatives, like a brown sugar substitute
  • Chocolate chips– Optional, but I love to fold through some vegan chocolate chips. 

The Instructions. 

Start by adding the mashed bananas, milk, and vanilla extract into a large mixing bowl and whisking together until combined. Next, add the dry ingredients and mix until a smooth batter remains. If using chocolate chips, fold them through at the end.

Now, transfer the batter into a greased loaf pan and bake for 45-50 minutes, or until a skewer comes out mostly clean from the middle. Let the protein banana bread cool in the pan completely, before slicing and serving.

Best protein powder for baking

Most protein powders will yield a moist and fluffy banana bread. However, avoid using whey protein powder as it is known to dry out baked goods. Here are the best kinds of powder to make this recipe- 

  • Brown rice protein powder– A vegan and dairy free protein powder that works very well in baked goods. Opt for a vanilla flavored powder, for a lovely vanilla flavor. 
  • Casein protein powder– My preferred protein powder blend, casein bakes beautifully and yields fluffy baked goods. Their flavored ones can be a little overpowering, so feel free to use an unflavored one. 
  • Other plant based protein powder– Hemp, pea, and soy protein powders all will work. 

Storing and freezing instructions

  • To store: Leftovers should always be stored in the refrigerator, covered. The banana bread will keep well for up to one week. 
  • To freeze: Place slices in a ziplock bag and store them in the freezer for up to 6 months.

    Yummy!!!! This was the best no added sugar recipe I have ever tried, even if it did poop on the oven floor as I didn’t use a big enough loaf pan. Will definitely be making it again—in a larger loaf pan.

    1. Not that I’ve tried. You can experiment and see 🙂 Whey protein is not recommended as it dries out baked goods!

  2. 5 stars
    This will definitely be on rotation for me! So good and I like that the serving sizes are big too. Thank you for sharing!

  3. 5 stars
    I love your recipes so much, I’ve made your protein pizza and this one also knocked it out of the park! Thanks for your clear, direct, and helpful explanations and recipes. And also thank you for introducing me to the magic of self rising flour!
    You’re becoming my go-to recipe website 🙂
    I didn’t have almond flour so I used bread flour and it seemed to work great. Also added an egg. Was perfectly moist and delicious 🙂

    I love your recipes! I just discovered you 2 days ago and I’ve already made 2 batches of different muffins and am planning on making this banana bread tomorrow. Thank you for healthy, but delicious recipes to share with my family.

  5. Hi! Love your recipes, thanks for sharing! I was wondering if I want to skip the protein powder, could I fill in the 1/4 cup with something else? If yes what could that be?

  6. 5 stars
    Do you recommend protein powders with minimal ingredients? It seems like so many have a million “superfoods” added. I’ve been trying a simple oat protein powder lately.

  7. I’m concerned if I use almond powder or peanut butter powder instead of protein powder (don’t have) it might not be moist and moistness is so necessary for banana bread, thoughts?

    1. Put 1 scoop of any of those or protein powder, even whey, and add 1 more very ripe banana (3 total) and see if that works. It did for me and I used whey and it turned out absolutely delicious!!!

  8. For those of us who are gluten-sensitive, can almond flour (or rice flour or potato flour) be substituted for the self-rising flour?

  9. 5 stars
    I missed the memo on the “self-rising” and used all purpose flower no baking powder. I would imagine the baking powder and salt help the cake consistency because the consistency I got was more like bread pudding. The flavor was still really good though. I can’t believe no eggs in recipe!

      I’ve made this twice. I used 1/2c peanut butter protein and 1/4c of whey and added a 3rd banana. Perfect moist, great taste and looks amazing!!
