Ingredients

Wet Ingredients

  • 3 medium ripe bananas, mashed Use very ripe bananas for the sweetest flavor.
  • 2 large eggs Can be replaced with flax eggs for a vegan version.
  • 1/2 cup plain Greek yogurt (non-fat or 2%) Adds richness and protein.
  • 2 tbsp honey or pure maple syrup Adjust to taste.
  • 1 tsp vanilla extract

Dry Ingredients

  • 1 cup oat flour (or 1 cup rolled oats blitzed to a flour) Ensure it's finely ground if using rolled oats.
  • 1/2 cup vanilla protein powder (whey or plant-based) Adjust sweetness based on protein powder used.
  • 1 tsp baking soda

  • 1/4 tsp salt

Optional Add-ins

  • 1/4 cup chopped walnuts, sugar-free chocolate chips, or hemp seeds Choose based on preference.

Instructions

Preparation

  • Preheat the oven to 175°C (350°F). Line a 9×5-inch loaf pan with parchment paper.
  • Mash the bananas until mostly smooth with a few small chunks for texture.
  • Whisk in the eggs, Greek yogurt, honey or maple syrup, and vanilla until combined.
  • In a separate bowl, combine the oat flour, vanilla protein powder, baking soda, cinnamon, and salt.
  • Gently fold the dry ingredients into the wet mixture. Stop mixing as soon as the batter is uniform.

Baking

  • Fold in any optional add-ins like walnuts or chocolate chips.
  • Pour the batter into the prepared loaf pan and smooth the top.
  • Bake for 45–50 minutes, or until a toothpick inserted in the center comes out clean.
  • Cool the loaf in the pan for 10–15 minutes, then lift out and cool completely before slicing.
