01 - Place the mashed bananas, eggs, milk, and vanilla extract into a blender. Process on medium speed 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 - Transfer the batter to a bowl if desired, then gently fold 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 thin layer of butter or oil.
05 - Pour approximately 1/4 cup of batter per pancake onto the heated skillet. Cook for 2 to 3 minutes until bubbles appear across the surface and the edges begin to set. Flip each pancake carefully and cook an additional 1 to 2 minutes until golden brown and cooked through.
06 - Remove finished pancakes and repeat with the remaining batter. Serve warm topped with fresh berries, nut butter, maple syrup, or any preferred accompaniments.
