Why You’ll Love This Recipe

I love this banana bread because it’s soft, chocolatey, and full of flavor—without being overly sweet or heavy. The added protein keeps me full longer, and it’s a great way to use up ripe bananas while staying on track with my nutrition goals. It’s easy to make in one bowl, freezer-friendly, and makes a great grab-and-go snack that feels like a treat but works like fuel.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Ripe bananas, mashed
Eggs
Greek yogurt (or unsweetened applesauce or mashed avocado)
Honey or maple syrup
Vanilla extract
Protein powder (chocolate or unflavored)
Unsweetened cocoa powder
Oat flour or whole wheat flour
Baking soda
Salt
Dark chocolate chips or chopped dark chocolate (optional)

Directions

I preheat the oven and grease or line a loaf pan with parchment paper.
In a large bowl, I mash the bananas, then whisk in the eggs, Greek yogurt, honey, and vanilla until smooth.
I stir in the protein powder, cocoa powder, baking soda, and salt.
I fold in the oat flour until just combined, then mix in chocolate chips if using.
I pour the batter into the prepared loaf pan and smooth the top.
I bake for 40–50 minutes, or until a toothpick inserted in the center comes out mostly clean.
I let it cool in the pan for 10 minutes before transferring to a wire rack to cool completely.

Servings and timing

This recipe makes 1 loaf, which yields about 10 slices. It takes around 10 minutes to prep and 40–50 minutes to bake, so I usually have it ready in about 1 hour total.

Variations

Sometimes I add chopped walnuts or pecans for crunch, or swirl in a spoonful of peanut butter for extra richness. I’ve also swapped oat flour with almond flour or used a mix of flours depending on what I have. For a boost of fiber, I stir in chia or flax seeds.

Storage/reheating

I store leftovers in an airtight container at room temperature for 2 days or in the fridge for up to 5 days. It also freezes well—I slice the loaf and wrap individual pieces to freeze for up to 2 months. To reheat, I microwave a slice for about 20 seconds or toast it lightly.

FAQs

What kind of protein powder should I use?

I use a chocolate or vanilla whey or plant-based protein powder that I enjoy the taste of. Unflavored protein also works if I want the cocoa and banana flavors to shine through.

Can I make it egg-free?

Yes, I’ve made it with flax eggs (1 tbsp flaxseed meal + 3 tbsp water per egg). The texture is slightly denser but still delicious.

Is it sweet enough without sugar?

Yes—between the bananas, honey, and chocolate chips, it’s perfectly sweetened for my taste. If I want it less sweet, I reduce the honey or skip the chips.

Can I make this gluten-free?

Definitely. I use certified gluten-free oat flour or a 1:1 gluten-free baking flour. Just make sure all your ingredients are labeled gluten-free.

Can I turn this into muffins?

Yes! I divide the batter into a lined muffin tin and bake at 350°F for about 18–22 minutes. They make great meal prep snacks.

Conclusion

High protein chocolate banana bread is one of my favorite ways to enjoy something sweet and satisfying while staying fueled and focused. It’s chocolatey, moist, and packed with nourishing ingredients that make every slice both delicious and purposeful. Whether I’m starting my day or looking for a healthy treat, this banana bread always delivers.
