Ingredients & Substitutions
Ingredient List
- 3 ripe bananas, mashed
- 2 large eggs
- 1/4 cup maple syrup or honey
- 1 teaspoon vanilla extract
- 1 1/2 cups oat flour (or finely ground rolled oats)
- 1/2 cup protein powder (vanilla or unflavored)
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon cinnamon
- 1/4 teaspoon salt
- 2 tablespoons melted coconut oil or butter
Optional mix-ins:
- 1/2 cup chopped walnuts or pecans
- 1/4 cup mini chocolate chips
Notes on Quality
Use very ripe bananas — the ones with lots of brown spots are perfect. For protein powder, a whey isolate or plant-based protein with minimal fillers works best to avoid any chalky texture. Freshly ground oat flour gives a softer result compared to store-bought.
Possible Substitutions
- Swap oat flour for almond flour for a nuttier flavor
- Use agave nectar instead of maple syrup or honey
- Replace coconut oil with olive oil or melted butter
- Add blueberries or chopped dates instead of nuts or chocolate
Step-by-Step Instructions

- Preheat your oven to 350°F and grease a loaf pan or line it with parchment paper.
- In a large bowl, mash the bananas until smooth.
- Add the eggs, maple syrup, vanilla extract, and melted coconut oil. Whisk until well combined.
- In a separate bowl, mix the oat flour, protein powder, baking soda, baking powder, cinnamon, and salt.
- Gradually stir the dry ingredients into the wet ingredients, being careful not to overmix.
- Fold in any optional mix-ins like nuts or chocolate chips.
- Pour the batter into the prepared loaf pan and smooth out the top.
- Bake for 35 to 40 minutes, or until a toothpick inserted into the center comes out clean.
- Allow to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Expert Tips & Tricks
Best Practices
- Always weigh your bananas if possible for consistency
- Don’t overmix the batter to keep the bread tender

Common Mistakes
- Using under-ripe bananas will make the bread less sweet and less moist
- Overbaking can dry out the loaf, so check it a few minutes early
- Skipping the parchment paper can make it harder to remove from the pan
Time-Saving Tips
- Mash bananas and store in the fridge a day ahead
- Use store-bought oat flour to skip grinding oats
- Double the recipe and freeze one loaf for later

Storage & Reheating
Leftover Storage
Store your banana bread in an airtight container at room temperature for up to 3 days or in the fridge for up to 5 days.
For longer storage, slice the loaf and freeze individual pieces wrapped in parchment paper inside a freezer bag. They’ll keep for up to 2 months.
Reheating Methods
- Microwave slices for about 10-15 seconds for that fresh-baked feel
- Toast slices lightly for a crisp edge and soft center
Frequently Asked Questions
Substitutions & Adjustments
Can I use a different flour? Yes, almond flour works great but it will make the bread slightly more crumbly.
Can I make it vegan? Swap the eggs for flax eggs (1 tablespoon flaxseed + 3 tablespoons water per egg) and use plant-based protein powder.
Troubleshooting
My bread turned out dry. What happened? It was likely overbaked or you used too much protein powder. Make sure to measure carefully and check for doneness early.
My loaf sank in the middle. Why? This can happen if there’s too much moisture or the loaf wasn’t fully baked before removing from the oven.
Variations & Customizations
Dietary Adaptations
- Make it dairy-free by using a plant-based protein and coconut oil
- Make it nut-free by skipping any nut mix-ins and using sunflower butter as a spread
Flavor Twists
- Add a teaspoon of cocoa powder for chocolate banana bread
- Stir in shredded coconut for a tropical vibe
- Swirl in a tablespoon of peanut butter into the batter before baking
