Updated: Nov 20, 2025

Banana bread is a classic treat that many love for its comforting flavor and moist texture. But finding a version that fits into a healthy lifestyle, especially one that is high in protein and gluten free, can be a challenge. This recipe is a simple, delicious solution inspired by my fav "Simple Mills" box brand banana bread, designed to satisfy your sweet tooth while supporting those goals. I just feel better about eating the whole pan when I make it this way....

Why This Banana Bread Recipe?


Many banana bread recipes rely heavily on refined flour and sugar, which can spike blood sugar and leave you feeling sluggish. This recipe swaps those ingredients for nutrient-dense alternatives that boost protein and fiber without sacrificing taste. It’s perfect for anyone who wants to enjoy healthy food that fuels their body, whether you’re a fitness enthusiast or just someone looking for better snack options.


This recipe is:


  • Gluten free to support those with sensitivities or gluten intolerance

  • Packed with high protein ingredients to help keep you full longer

  • Made with natural sweeteners and wholesome flours

  • Easy to prepare with common pantry staples


Ingredients You’ll Need


Here’s what makes this banana bread both nutritious and delicious:


  • 3 ripe bananas (the riper, the sweeter)

  • 3 large eggs

  • 1/4 cup coconut oil or olive oil

  • 1/4 cup pure maple syrup or honey (optional for extra sweetness)

  • 1 teaspoon vanilla extract

  • 1 1/2 cups almond flour (gluten free and high in protein)

  • 1/2 cup oat flour (certified gluten free)

  • 1/4 cup protein powder (vanilla or unflavored, plant-based or whey)

  • 1 teaspoon baking soda

  • 1/2 teaspoon sea salt

  • 1 teaspoon cinnamon (optional)

  • 1/4 cup chopped walnuts or pecans (optional for crunch)


Step-by-Step Instructions


  1. Preheat your oven to 350°F (175°C). Grease a 9x5 inch loaf pan or line it with parchment paper.

  2. In a large bowl, mash the bananas until smooth.

  3. Add the eggs, oil, maple syrup (if using), and vanilla extract. Whisk until well combined.

  4. In a separate bowl, mix the almond flour, oat flour, protein powder, baking soda, salt, and cinnamon.

  5. Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined. Avoid overmixing.

  6. Fold in the nuts if you want some texture.

  7. Pour the batter into the prepared loaf pan and smooth the top.

  8. Bake for 20 minutes. Put tinfoil loosely over the pan and bake for another 25. Check doneness by inserting a toothpick in the center; it should come out clean or with a few moist crumbs.

  9. Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.


Tips for Perfect Banana Bread


  • Use very ripe bananas with brown spots for natural sweetness and moisture.

  • If you don’t have oat flour, you can make your own by grinding gluten free oats in a blender.

  • Adjust sweetness by reducing or omitting maple syrup if you prefer less sugar.

  • For extra protein, add a tablespoon of chia seeds or flaxseeds.

  • But a banana in half long ways and place on top before baking

  • Store leftovers in an airtight container at room temperature for 2 days or refrigerate for up to a week.

  • Drizzle honey or peanut butter on top!!!
