01 - Combine the mashed bananas, eggs, milk, and vanilla extract in a blender. Process on high until the mixture is completely smooth and uniform.
02 - Add the rolled oats, protein powder, baking powder, cinnamon, and salt directly into the blender with the wet mixture. Blend until a smooth, lump-free batter forms.
03 - Stir in chia seeds, flaxseed, walnuts, or chocolate chips if using. Allow the batter to rest for 2 to 3 minutes so it thickens slightly.
04 - Set a non-stick skillet or griddle over medium heat. Lightly grease the surface with cooking spray or a small amount of butter or oil.
05 - Pour approximately 1/4 cup of batter per pancake onto the hot skillet. Cook for 2 to 3 minutes until bubbles rise and pop across the surface. Flip each pancake and cook an additional 1 to 2 minutes until golden brown and cooked through.
06 - Transfer finished pancakes to a warm plate and repeat with the remaining batter. Serve immediately with fresh berries, nut butter, or maple syrup.
