Make a moist, protein-packed loaf that works well for breakfast or a satisfying snack. This recipe uses Greek yogurt and protein powder for a healthy boost.

Ingredients

Scale
  • 3 very ripe medium bananas, mashed
  • 1/2 cup plain Greek yogurt (2% or full fat recommended for moisture)
  • 1/4 cup melted coconut oil or unsalted butter
  • 1/4 cup maple syrup or honey
  • 1 teaspoon vanilla extract
  • 2 scoops (about 60g) vanilla or unflavored protein powder (whey or casein blend works best)
  • 1 cup oat flour (or all-purpose flour)
  • 1 teaspoon baking soda
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup chopped walnuts or pecans (optional)

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, combine the mashed bananas, Greek yogurt, melted oil or butter, maple syrup, and vanilla extract. Mix until just combined.
  3. In a separate medium bowl, whisk together the protein powder, oat flour, baking soda, cinnamon, and salt.
  4. Add the dry ingredients to the wet ingredients. Mix gently with a spatula until you have a uniform batter. Do not overmix.
  5. If using, fold in the chopped nuts.
  6. Pour the batter into the prepared loaf pan and spread evenly.
  7. Bake for 45 to 55 minutes, or until a toothpick inserted into the center comes out clean or with moist crumbs attached.
  8. Let the bread cool in the pan for 10 minutes before carefully transferring it to a wire rack to cool completely before slicing.

Notes

  • For the best texture, use a protein powder that is casein-heavy or a blend, as 100% whey can sometimes lead to a slightly drier result.
  • If you prefer a lower sugar banana bread, reduce the maple syrup to 3 tablespoons and add 1/4 teaspoon of stevia or monk fruit sweetener.
  • This bread is excellent for meal prep. Wrap individual slices tightly in plastic wrap and store them in the freezer for up to two months.
