Ingredients
Method
- Preheat oven to 350°F (175°C) and line a 9x5-inch loaf pan with parchment. Mash the 3 bananas in a large bowl until mostly smooth.
- Add the 1/2 cup yogurt, 1/4 cup melted oil, 2 eggs, 1 tsp vanilla, and 1/2 cup sugar; whisk until smooth, about 1 minute.
- Sprinkle the 1 cup protein powder, 1 cup flour, 1 tsp baking soda, 1/2 tsp salt, and cinnamon over the wet ingredients. Fold with a spatula just until no dry streaks remain; stir in walnuts or chocolate chips if using.
- Scrape batter into the pan and smooth the top. Bake 45-50 minutes until a toothpick comes out with moist crumbs. Cool in pan 10 minutes, then lift out and cool on a rack.
- Slice and serve warm, with almond butter or honey if you like.
Notes
Cool completely before storing, or trapped steam will soften the crust. For a nut-free version, skip the walnuts or use chocolate chips. The loaf slices best with a serrated knife.
