Ingredients

Main Ingredients

  • 3 medium ripe bananas, mashed Very ripe — lots of brown spots for best sweetness and moisture
  • 2 large eggs
  • 1/2 cup plain Greek yogurt (non-fat or 2%) Adds creaminess and protein
  • 2 tbsp honey or pure maple syrup Adjust to taste
  • 1 tsp vanilla extract
  • 1 cup oat flour Or use rolled oats blended to a fine flour
  • 1/2 cup vanilla protein powder Whey or plant-based
  • 1 tsp baking soda If your protein powder is very dense, add 1/2 tsp baking powder as an optional lift
  • 1/2 tsp ground cinnamon
  • 1/4 tsp salt

Optional Mix-ins

  • 1/4 cup chopped walnuts Optional
  • 1/4 cup sugar-free chocolate chips Optional
  • 1/4 cup hemp seeds Optional

Instructions

Preparation

  • Preheat the oven to 175°C (350°F). Line a 9×5-inch loaf pan with parchment and set aside.
  • Mash the ripe bananas in a large bowl until mostly smooth.
  • Whisk in the eggs, Greek yogurt, honey (or maple), and vanilla until well combined.
  • In a separate bowl, stir together oat flour, protein powder, baking soda, cinnamon, and salt.
  • Add the dry mix to the wet ingredients. Fold gently until just combined — don’t overmix.
  • If using, fold in walnuts, chocolate chips, or hemp seeds.
  • Pour batter into the prepared loaf pan and smooth the top with a spatula.
  • Bake for 45–50 minutes, or until a toothpick inserted into the center comes out mostly clean (a few moist crumbs are fine).
  • Cool in the pan for 10–15 minutes, then transfer to a wire rack to cool completely before slicing.

Notes

For best results, use very ripe bananas and avoid overmixing the batter. Store wrapped in plastic wrap or in an airtight container.
