There are few things more comforting than the smell of banana bread baking in the oven. It’s the kind of smell that stops you mid-thought, mid-task, and reminds you to just breathe. It’s warm. Familiar. Homey. And in my house, it often meant something was past its prime—usually a bunch of bananas speckled with spots no one wanted to touch. That’s when I’d tie on my apron and make something out of almost nothing.
This protein banana bread came about during one of those ordinary mornings when I stood staring at three overripe bananas on the counter. I was craving something sweet but satisfying. Something that wouldn’t leave me hungry an hour later. That’s when I remembered a friend raving about adding protein powder to baked goods. I’d tried it before, but the results were always too dry or had that weird chalky aftertaste. So I set out to do it right—moist, rich, banana-forward, with that classic banana bread texture… but with a little extra staying power.
It took a few tries (one batch turned out so dense it could’ve doubled as a doorstop), but this version? This is the one I come back to again and again. It’s comforting and familiar—but quietly powerful. And best of all, it doesn’t taste like health food.

Ingredients You’ll Need
Let’s break it down. These ingredients are simple, flexible, and you probably have most of them on hand:
- 3 ripe bananas – The riper the better. Brown spots mean more sweetness and a softer texture.
- 2 large eggs – They help bind the bread and add moisture.
- 1/3 cup maple syrup – I love the subtle caramel flavor this adds. You can swap it for honey if needed.
- 1/2 cup plain Greek yogurt – Adds protein and moisture. I’ve also used almond milk yogurt for a dairy-free version.
- 1 teaspoon vanilla extract – Pure vanilla if possible—it really deepens the flavor.
- 1 cup oat flour – I blend rolled oats in my blender. It’s naturally gluten-free (if using certified GF oats) and gives a lovely texture.
- 1/2 cup vanilla or unflavored protein powder – I use a plant-based protein with a clean ingredient list. If you’re using whey, reduce liquid slightly as it absorbs differently.
- 1 teaspoon baking soda – For that perfect rise.
- 1/2 teaspoon cinnamon – Optional, but adds a cozy warmth.
- 1/4 teaspoon salt – Just enough to balance the sweetness.
- Optional add-ins: 1/3 cup chopped walnuts, dark chocolate chips, or blueberries—because why not?
How to Make It (Step-by-Step Instructions)
Pull up a chair and let’s bake this together. I’ll walk you through exactly how I make it in my kitchen.
Step 1: Preheat and Prep
Set your oven to 350°F (175°C) and grease a standard 9×5 loaf pan. I sometimes use parchment paper for easy lifting—especially if I’m gifting it to someone.
Step 2: Mash Those Bananas
In a large mixing bowl, mash the bananas until mostly smooth. A few small chunks are totally fine—they melt into sweet little pockets.
Clara’s Tip: Don’t over-mash into a liquid. You want some texture.
Step 3: Add Wet Ingredients
To the mashed bananas, add the eggs, maple syrup, Greek yogurt, and vanilla. Whisk until smooth and creamy. It should already smell amazing.
Step 4: Fold in Dry Ingredients
In a separate bowl, whisk together the oat flour, protein powder, baking soda, cinnamon, and salt. Slowly fold the dry ingredients into the wet. Don’t overmix—just until no streaks remain.
Clara’s Mistake to Avoid: I once beat the batter too hard, thinking it would make it fluffier. It actually made it tough. Be gentle here.
Step 5: Add Your Extras
Fold in any extras you like—walnuts for crunch, chocolate chips for decadence, or blueberries for a fruity twist. Today, I added chopped pecans and a sprinkle of hemp seeds.
Step 6: Bake
Pour the batter into your prepared loaf pan. Smooth the top and bake for 40–50 minutes, until a toothpick inserted in the center comes out clean. Let it cool in the pan for 10 minutes, then transfer to a wire rack.
Clara’s Note: Don’t rush the cooling! It sets the texture. I’ve sliced too early before and ended up with gummy bread.
Expert Tips for the Best Results
The feel was soft and had a nut-like taste, but was a bit easy to break.
Variations & Substitutions
This recipe has evolved with me through pantry shortages and flavor experiments.
One Saturday morning, I was out of yogurt and used applesauce instead. It worked beautifully—moist, slightly sweeter, and totally kid-approved.
Another time, I subbed almond flour for half the regular flour. The feel was soft and had a nut-like taste, but was a bit easy to break. Perfect with a smear of almond butter.
For a fall twist, I’ve added pumpkin puree (about 1/2 cup, subbed for one banana) and warm spices like nutmeg and ginger. It was like banana bread met pumpkin pie—and yes, it disappeared fast.
Serving Suggestions
This banana bread pairs beautifully with a dollop of nut butter and a sprinkle of chia seeds for breakfast. I’ve also served it warm with Greek yogurt and berries for a light lunch, or alongside coffee as an afternoon pick-me-up.
It travels well for road trips, fits into lunchboxes, and makes a lovely little gift for a friend or neighbor (wrap it in parchment and twine—it’s charming and practical).
Storage & Reheating Instructions
Storage: I wrap the cooled loaf tightly in foil or keep it in an airtight container. It lasts about 3–4 days on the counter or up to a week in the fridge.
Freezing: To freeze, cut the loaf and wrap each part in paper, then put them in a zip-top bag for the freezer. That way, you can grab one at a time.
Reheating: A quick toast in the oven (or air fryer) at 300°F for 5–8 minutes revives the texture. At times, I pour a bit of maple syrup and add crushed walnuts on top—just cozy.
Recipe FAQs (Answered by Clara)
Can I use plant-based protein powder?
Yes, but results can vary. I’ve used pea protein and found the loaf a bit denser, but still good. Try to choose a neutral flavor.
Can I make this recipe gluten-free?
Absolutely. I’ve had success using a 1:1 gluten-free flour blend. Just make sure your protein powder is also gluten-free.
Can I turn this into muffins?
Yes! I’ve done this for grab-and-go breakfasts. Just divide the batter into a lined muffin tin and bake at 350°F for 18–22 minutes.
Do I need a stand mixer?
Not at all. I make this by hand in two bowls. Less cleanup, more charm.
How can I make it sweeter?
Add 2–3 tablespoons of brown sugar or more maple syrup. But if your bananas are ripe enough, you may not need to.
Conclusion
This protein banana bread has become one of those recipes I turn to over and over again. It’s nourishing, adaptable, and deeply comforting. For a fast morning meal, a snack to keep you going, or a treat that’s a bit good for you—it works.

Protein Banana Bread
Ingredients
- 3 ripe bananas mashed
- 2 eggs
- 1/2 cup Greek yogurt or protein yogurt
- 1/4 cup almond milk or any milk of choice
- 1/4 cup honey or maple syrup
- 1 tsp vanilla extract
- 1 1/2 cups oat flour or all-purpose flour
- 1/2 cup vanilla protein powder
- 1 tsp baking soda
- 1/2 tsp ground cinnamon
- 1/4 tsp salt
- 1/2 cup dark chocolate chips or nuts optional
Instructions
- Preheat the Oven and Prepare the Pan: Preheat your oven to 350°F (175°C) and grease a loaf pan with a bit of cooking spray or line it with parchment paper.
- Mash the Bananas: In a large mixing bowl, peel and mash the ripe bananas with a fork until they are smooth with just a few chunks. The riper the bananas, the easier they will mash, and the sweeter your bread will be!
- Combine Dry Ingredients: Add the eggs, Greek yogurt, honey (or maple syrup), and vanilla extract to the mashed bananas. Whisk everything together until well combined.
- Combine Dry Ingredients: In another bowl, whisk together the whole wheat flour, protein powder, cinnamon, baking powder, and salt. This ensures that the dry ingredients are evenly distributed before mixing them into the wet ingredients.
- Mix the Wet and Dry Ingredients: Add the dry ingredients into the wet ingredients and stir gently until just combined. Be careful not to overmix, or your bread may turn out dense. If you’re adding any optional ingredients like nuts, chocolate chips, or seeds, fold them in at this stage.
- Bake the Banana Bread: Pour the batter into your prepared loaf pan and spread it out evenly. Bake in the preheated oven for 45-55 minutes, or until a toothpick inserted into the center comes out clean. If the top starts to brown too quickly, you can cover the loaf with aluminum foil during the last 10-15 minutes of baking.
- Let It Cool: Once baked, remove the banana bread from the oven and let it cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely before slicing.
Notes
- Protein Powder: You can use any flavor of protein powder you like. Vanilla works best to complement the banana flavor, but chocolate or plant-based protein powders can also be used for a unique twist.
- Flour Options: If you’re looking to make this recipe gluten-free, substitute oat flour with a gluten-free flour blend or almond flour.
- Sweetener Adjustments: You can adjust the sweetness by adding more or less honey/maple syrup, depending on your taste and the ripeness of your bananas.
- Banana Ripeness: The riper the bananas, the sweeter and more flavorful the bread will be. Overripe bananas work best.
- Add-ins: For extra texture and flavor, you can mix in nuts (like walnuts or pecans), chocolate chips, or dried fruit.
- Storage: Store your protein banana bread in an airtight container at room temperature for up to 3 days, or refrigerate it for up to a week. It can also be frozen for longer storage.
- Protein Variations: If you don’t have protein powder, you can omit it and replace it with extra oat flour or almond flour. You can also add extra Greek yogurt for added protein.
