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