Prepare Batter: In a mixing bowl, mash the ripe bananas until smooth. Add the eggs and whisk together until well combined.

Mix Dry Ingredients: In a separate bowl, combine rolled oats, protein powder, baking powder, and cinnamon if using.

Combine Wet and Dry Ingredients: Gradually add the dry ingredients to the banana and egg mixture, stirring until a smooth batter forms. Let the batter rest for about 5-10 minutes to thicken.

Cook Pancakes: Heat a non-stick skillet or griddle over medium heat. Lightly grease with cooking spray or butter. Pour about 1/4 cup of batter for each pancake onto the skillet. Cook for 2-3 minutes, or until bubbles form on the surface.

Flip and Cook: Carefully flip the pancakes and cook for an additional 1-2 minutes, or until golden brown and cooked through.

Serve: Remove from the skillet and serve warm. Optional toppings include fresh berries, sliced bananas, yogurt, or a drizzle of honey.
