Ingredients

Scale
  • 3 very ripe large bananas, mashed
  • 1/2 cup plain non-fat Greek yogurt
  • 1/4 cup melted coconut oil or unsalted butter
  • 1/2 cup pure maple syrup or honey
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup oat flour
  • 1/2 cup vanilla or unflavored protein powder (whey or plant-based)
  • 1 teaspoon baking soda
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • Optional: 1/2 cup chocolate chips or chopped walnuts

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a standard 9×5 inch loaf pan, or line it with parchment paper.
  2. In a large bowl, mash the ripe bananas until mostly smooth.
  3. Add the Greek yogurt, melted coconut oil, maple syrup, eggs, and vanilla extract to the mashed bananas. Whisk these wet ingredients together until they are well combined.
  4. In a separate medium bowl, whisk together the oat flour, protein powder, baking soda, cinnamon, and salt.
  5. Add the dry ingredients to the wet ingredients. Mix gently with a spatula only until just combined. Do not overmix; a few streaks of flour are acceptable.
  6. If using, fold in the chocolate chips or walnuts now.
  7. Pour the batter into the prepared loaf pan and spread it evenly.
  8. Bake for 45 to 55 minutes, or until a toothpick inserted into the center comes out clean.
  9. Let the bread cool in the pan for 10 minutes before carefully removing it to a wire rack to cool completely before slicing.

Notes

  • For the moistest result, use bananas that are heavily spotted or almost black.
  • If your protein powder is very absorbent, you may need to add one extra tablespoon of milk or water to keep the batter loose.
  • This bread is excellent for meal prep and keeps well stored in an airtight container at room temperature for up to three days, or refrigerated for up to one week.
