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.
My high protein banana bread recipe is a winner! I tested it thousands of times to make sure it looked and tasted like banana bread—but with protein powder added! It makes a fabulous post-workout snack or wholesome dessert you can feel good about eating.
Table of Contents
Why I 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 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 25 grams of protein, so you’ll feel fuller for longer!
- No eggs or dairy is needed, so those who follow a vegan diet can definitely enjoy a slice or two.
Key Ingredients
- Ripe 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 (it’s just all-purpose flour, salt, and baking powder). I tested this recipe with oat flour and found the loaf to be a little too dry for my liking.
- Almond flour. Blanched almond flour, not almond meal. The latter will yield a dense and doughy loaf instead of a fluffy one.
- 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. You can use a liquid sweetener like honey or maple syrup, but reduce the amount by half.
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 I’ve tested with 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 vegan protein powder- Hemp protein, pea protein, and soy protein powders all will work.
How to make protein banana bread
I’ve included step-by-step photos below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post.
Step 1- Make the batter. In a large bowl, combine the wet ingredients. Next, add the dry ingredients and mix until a smooth batter remains.
Step 2- Bake. 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.
Arman’s recipe tips
- Do not overbake the banana bread, as it will continue to bake as it cools down. Once a toothpick comes out mostly clean, it’s ready to be removed from the oven.
- If your banana bread is browning too quickly, cover the top of the bread with some tin foil after around 15-20 minutes. This might not happen to you, it all depends on the brand of protein powder AND how your oven bakes things.
- You can use this batter to make banana protein muffins. Simply bake it in muffin liners and reduce the cooking time to 18 minutes.
- Feel free to fold through fun mix-ins to change up the texture. Try walnuts, pecans, dark chocolate chips, peanut butter, nut butter, white chocolate chips, or even dried fruit.
Storage instructions
To store: Leftovers will keep well at room temperature, covered with plastic wrap, for 2-3 days. For longer storage, store the slices in a fridge for a week in an airtight container.
To freeze: Place slices in a ziplock bag and store them in the freezer for up to 6 months.
Frequently asked questions
While a classic loaf of banana bread has some protein in it, it is not enough to be classified as a high-protein food.
My protein banana bread has at least 18 grams of protein per slice. Adding walnuts or almonds on top will add even more protein.
If you use gluten-free self-rising flour (as Dove Farms), this banana bread is gluten-free.
As long as you use a dairy-free and egg-free protein powder, this recipe is 100% vegan.

I must buy almond flour for this. I never tried in recipes.
Damn good!!!
I preapred this banana bread last week and it was much better than my usual bread.
Made this twice now. Quick easy and delicious. Great recipe!
Today I made this. I added banana flavour whey
Protein. I cannot believe the taste. It was amazing!
Wow I just bought banana protein powder. So I really need to try this recipe. Banana explosion.
What if I put coconut flour instead of almond? Would it be the same?
I will do this. I just bought whey protein banana flavour so it will fit perfectly.
Can I go without the almond flour? Is it just for taste?
It helps with structure like any other flour would.
Can you pack this to travel for a 3-4 hour ride?
Yeah for sure!! I always pack some when we go to our studio house (2 1/2 hours away) and usually forget its there until snack time : )
Thank you!! I made a triple batch, it is SO delicious and addictive! And healthy:)
Hi! Can I swap out some of the flour for more protein powder?
I haven’t tried but feel free to experiment and see!
I only have whey protein. Is there any way I can adjust the recipe to work with whey?
I never had success with whey, but it could also be the brands I used. Feel free to experiment and see.
Can I swap out some of the flour for more protein powder?
I made some minor changes to the recipe based on what I had and what I thought would make it still work for me.
It was really tasty!
Differences= 3 bananas; 2% milk, no almond flour; hearty 1/4 cup protein powder; regular brown sugar & mixed in the chocolate chips.
Yummy with a bit more protein.
best protein banana bread recipe ever!
This is absolutely out of this world! Made a loaf and ate it all myself! Ate it for breakfast and it kept me full a satisfied all morning. Was wonder why you always Linda pan with parchment paper instead of greasing and flouring the pan? I have a difficult time lining the pan neatly with parchment paper.
This recipe turned out perfect as muffins in 17 minutes! I made my own self rising flour with King Arthur GF flour + baking powder + salt, and followed the rest of the recipe exactly. They were not the moist texture that banana bread usually is, but nonetheless soft and delicious!
Love that!!!
C An coconut flour substitute almond flour?
Not for this recipe, sorry!
It’s rare that I take the time to review a recipe I found on the internet but this is hands down amazing! Moist, no protein flavor, cakey, no added sugar, and no eggs, for my LO who has an egg allergy. Thank you so much for putting this delicious recipe out!!!
You are so welcome, K!
BEST protein banana bread recipe!!!!! I saw this on Instagram and knew I had to make it!
Race reviews Arman, nice work! I’d love to try it but was wondering if there’s a sub for the almond flour for an allergy friendly version? Thank you so much ☺️🫶🏻🩷
You could try sunflower seed flour!
*rave! Autocorrect is crazy 🤪
Thank you so much Arman 🙏🏻🩷 I have some pumpkin seed flour so figure it’s probably similar to sunflower seed flour so will give it a whirl!! Have a great conference 🤗💕🩷💕
Thanks, Cerys! Yes, pumpkin seed flour and sunflower seed flour is a great alternative to almond flour.
Where do the 10g of fat come from?
The almond flour 🙂
This is such a good protein banana bread. Tastes like real banana bread.
Thanks, Holly. We love it too!
Best protein banana bread recipe I’ve ever made!!! It’s just too good.
The BEST protein banana bread recipe ever!

This banana bread is Amazing! I can’t believe how good it tastes using such simple ingredients and no processed sugar . I’ve been making it on repeat for my evening snack!
The best protein banana bread recipe. I make this all the time.
This is super moist and fluffy.
so good – best protein banana bread i;ve ever had!
The best moist and fluffy protein banana bread that actually tastes like real banana bread.
What can I substitute for all purpose flour please! Thanks
Haven’t tried any alternatives, you are welcome to experiment and see!
so good. I had to tent the bread so the edges didn’t overcook/burn. I also had like 15 min of cook time. Super delicious though; the whole family loved it.
Hi Arman, thank you for another yummy scrummy looking recipe!
Just wondering for dubs for almond flour…. could I use polenta! Thinking of a low fat allergy friendly alternative 🙂
Thank you so much!
Hi there- Saw your earlier comment 🙂 Good luck with the sunflower seed flour 🙂
Excellent recipe, thank you. No issues using dairy milk or whey protein protein.
Great to hear, Em!
Super moist. I added chocolate chips and walnuts too.
Great to hear that, Jordan!
Great recipe!
Best recipe. I love how amazing the texture is!
Great to hear that, Margo!
Seriously the best protein banana bread recipe I’ve ever made!
omg this protein banana bread is to die for!!
Which protein powder would you recommend for this recipe? I tried this with whey protein (that’s all I had available) but it came out goes and not cakey at all, and I’m guessing it’s due to the protein powder
Oh yes, whey protein dries out baked goods. Always use casein or brown rice protein. I used optimum casein 🙂
I used monkfruit sweetener and honey, plus walnuts instead of choc chips. Amazing! Will definitely make this one again
Can it work well with other flours such as oat flour instead of almond flour? Thanks
Hi Julia! Almond flour can be subbed with sunflower seed flour or cashew flour.
Delicious banana bread. Everyone in my family loves it including my 4yo daughter. Thank you!
Love that, Carmen!
Can I use all purpose, self rising, whole wheat, or cake flour as a substitute for the almond flour?
I haven’t tried but you are welcome to experiment and see!
Fabulous protein banana bread.
Great to hear that, Keeley!
I’ve made this recipe so many times! I add a tablespoon of vegetable oil to the protein banana bread mixture for moistness. I love this and the almond flour brownies recipe. These are amazing! Can’t wait to try more awesome recipes. Thank you
Best protein banana bread ever!
Excellent recipe! I used whey protein powder (Gold Standard Vanilla Ice Cream to be specific), and it came out perfect. Thanks so much!
Thanks for letting me know, Julie- that is super helpful that there is a whey protein brand that works 🙂
This is the best protein banana bread recipe I’ve ever made. So moist and tender.
The ultimate test is if the kids like it. All my kids love it. It was devoured in no time. It’s my go to Banana Bread now.
I don’t generally keep almond flour around. Could I do a cup of protein powder instead or would that not work?
I’m not sure- I haven’t tried it 🙂
Adding everything into MFP and I’m actually getting a higher protein count- love that! this is the best protein banana bread recipe I’ve ever made.
I have tried a lot of healthy banana bread recipes and this is the best by far. Added one extra banana when I made it and it was perfect.
How much is considered one serving?
one slice 🙂
This has a really good texture- I love it!
Thanks for these recipes!
Just made this for the tenth time- it’s so good!!
So I loved this recipe! Definitely making over and over again!
I used whey protein powder in the recipe and it still turned out great 🙂
The best protein banana bread recipe ever.
What flavor protein powder I use?
Plain or vanilla is best, but feel free to use other flavors too- your banana bread will just taste a little like that 🙂
Just curious did you include the chocolate in your calorie math? Thanks!
We didn’t, as they are optional 🙂
This protein banana bread is really delicious and super easy to make. Moist and fluffy is definitely an accurate description! Just recently discovered your website and I look forward to trying more of your recipes!

ABSOLUTELY THE BEST!!!
Question, is cake flour or pastry flour the same as self rising flour?
Can I substitute the protein powder for the collagen peptide powder?
You could try!
Thanks so much for sharing this recipe!! It came out super moist and very tasty. I used vanilla whey protein powder and for the flour – 1 c white and 1 c whole wheat, using your recipe for self rising flour (thanks for including the link to that in this recipe!). Will be making this again soon.
I’m not a seasoned baker so I wish you could’ve explained the self-rising flour part. Made my whole thing without baking powder and it ruined my day 🙁
The BEST banana bread we’ve ever tasted! I even used Whey Protein! I simply added an extra very ripe, I mean mushy brown, banana and it came out perfectly moist. We’ve made this twice in two weeks.
Can I add regular milk instead of almond milk?
absolutely!
Amazing banana bread! We replaced the almond flour with half coconut flour and extra milk and it still tasted delicious! Great recipe 🙂
Can you eliminate the almond flour??
You can replace it with wheat or white flour.
You can but you can’t even taste the almond flour and it doesn’t make it gritty.
For normal poeple
240ml Milk
1 tablespoon Vinegar
1 tablespoon Vanilla extract
240g Flour
1 tablespoon Baking powder
50g Almond flour
30g Protein Powder
100g Surag substitute
85g Chocolate chips
Love it! Thank you so much, it’s all about the grams for baking 😀
Can I swap out the rice protein for whey protein isolate?
You can try and see
Would you be able to taste the vinegar?
not at all 🙂
Would help if you told us what temperature to cook it in the oven at….
What do you think the recipe card is for? Decoration?
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!!
For those of us who are gluten-sensitive, can almond flour (or rice flour or potato flour) be substituted for the self-rising flour?
Not that I’ve tried! But gluten free self-rising flour works too!
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?
No idea- I haven’t used either of those so I can’t vouch for it.
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!!!
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.
That’s true- Try looking for a brown rice blend with no added sugar 🙂
We make this protein banana bread at least 3 times a week.
FORALL is the best protein powder! Only one ingredient and completely tasteless.
The best protein banana bread recipe I’ve ever made- super moist, fluffy, and tastes like the real thing!
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?
Yes, use white or wheat flour.
Can I leave the protein powder out?
Sure! Try wheat or white flour.
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.
Can the protein powder be omitted?
Yes!
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 used 4 small bananas & 1 cup spelt & 1 cup regular flour (added 4 tsp baking powder & sieved it) plus sugar free choc chips – turned out really good 👍 thanks will make again
I doubled the protein powder to amp it up- I added a little extra liquid to compensate 🙂
Great to hear it worked!
This will definitely be on rotation for me! So good and I like that the serving sizes are big too. Thank you for sharing!
Is there a way to make this nut free? And would whey protein powder work?
Not that I’ve tried. You can experiment and see 🙂 Whey protein is not recommended as it dries out baked goods!
Is there anything that can be substituted for almond flour for someone with nut allergies?
Not that I’ve tried. You can experiment and see 🙂
Would Coconut flour work in place of almond flour.
No it will not.
Made this today, super yummy and the macros were really good (160 cal, 19g protein for a small slice). I used high protein self raising flour as well as my usually vanilla pea protein powder (White Wolf) and it definitely bumped up that number without ruining the flavour.
Only change I made was an extra 1/2 cup of milk, as the batter was a little too dry for my liking. 1.5cups of milk made the texture perfect and the banana bread was moist!
Will definitely make this one again 🙂
We make this loaf at least once a week!
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.
