01 - Combine the mashed bananas, eggs, milk, and vanilla extract in a blender. Blend until completely smooth and no large banana chunks remain.
02 - Add the rolled oats, protein powder, baking powder, ground cinnamon, and salt to the blender. Blend until a smooth, uniform batter forms.
03 - Stir in chia seeds, flaxseed, walnuts, or chocolate chips if desired. Let the batter rest for 2 to 3 minutes to allow it to thicken slightly.
04 - Place a non-stick skillet or griddle over medium heat and lightly grease with cooking spray or butter.
05 - Pour approximately 1/4 cup of batter per pancake onto the hot skillet. Cook for 2 to 3 minutes until bubbles form across the surface and edges appear set. Flip carefully and cook another 1 to 2 minutes until golden brown and cooked through.
06 - Repeat with the remaining batter, adjusting heat as needed between batches. Serve warm with fresh berries, nut butter, or maple syrup.
