01 - Place the mashed bananas, eggs, milk, and vanilla extract into a blender. Blend 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 - Stir in chia seeds, ground flaxseed, chopped walnuts, or chocolate chips if desired. 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 appear across the surface and the edges look set. Flip carefully and cook another 1 to 2 minutes until golden brown and cooked through.
06 - Transfer cooked pancakes to a warm plate and repeat with the remaining batter. Serve immediately with fresh berries, nut butter, maple syrup, or your preferred toppings.
