High-Protein Banana Bread

Preheat the oven to 350 degrees F (175 degrees C). Spray a 9x5-inch loaf pan with cooking spray.

Mix together oat flour, sugar, walnuts, protein powder, cinnamon, baking powder, and baking soda in a medium bowl.

Mix together mashed bananas, applesauce, milk, egg whites, and vanilla extract in a large bowl. Slowly add flour mixture to banana mixture; stirring until just combined. Transfer batter into the prepared loaf pan.

Bake in the preheated oven until top of bread springs back when lightly pressed and a toothpick inserted into the center comes out clean, 35 to 40 minutes. Cool in the pan for 10 minutes. Transfer to a wire rack to cool completely.
