High Protein Banana Bread Breakfast Bake (No Flour, No Refined Sugar) - Cozy, Filling, and Easy

Prep Time 10 minutes
Cook Time 35 minutes
Total Time 45 minutes
Servings 6 servings

Ingredients
  

  • 3 large ripe bananas (spotty and soft)
  • 2 large eggs
  • 1 cup plain Greek yogurt (2% or whole milk for best texture)
  • 1/4 cup pure maple syrup or honey
  • 1 teaspoon vanilla extract
  • 2 cups old-fashioned rolled oats (not instant)
  • 1/2 cup vanilla or unflavored whey or plant-based protein powder (optional but boosts protein)
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon fine salt
  • Optional mix-ins: 1/3 cup chopped walnuts or pecans, 1/4 cup dark chocolate chips, 2 tablespoons chia or flax seeds

Instructions
 

  • Preheat your oven to 350°F (175°C). Grease an 8x8-inch baking dish or line it with parchment for easy removal.
  • In a large bowl, mash the bananas until mostly smooth. Whisk in the eggs, Greek yogurt, maple syrup, and vanilla until creamy.
  • In the same bowl, add the oats, protein powder (if using), baking powder, baking soda, cinnamon, and salt. Stir until the oats are evenly coated and the batter is thick and cohesive.
  • Fold in any optional mix-ins like nuts, seeds, or chocolate chips.
  • Spread the batter into the prepared dish, smoothing the top. Let it sit for 5 minutes so the oats can hydrate slightly.
  • Bake for 28–35 minutes, or until the center is set and the top is lightly golden. A toothpick should come out mostly clean with a few moist crumbs.
  • Cool for at least 15 minutes before slicing. It firms as it cools, making cleaner slices.
