01 - Combine the mashed bananas, eggs, milk, and vanilla extract in 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 to the blender. Blend until a smooth, lump-free batter forms, scraping down the sides as needed.
03 - Transfer the batter to a bowl if desired, and fold in any optional add-ins such as chia seeds or chopped walnuts. Let the batter rest for 2 to 3 minutes to allow it to thicken slightly.
04 - Heat 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 form across the surface and the edges appear set. Flip carefully and cook an additional 1 to 2 minutes until golden brown and cooked through.
06 - Remove cooked pancakes from the skillet and repeat with the remaining batter. Serve warm topped with fresh berries, nut butter, maple syrup, or your preferred toppings.
