01 - Place bananas, eggs, almond milk, and vanilla extract in a blender. Blend on high until completely smooth and no banana lumps remain.
02 - Add oats, protein powder, baking powder, cinnamon, and salt to the blender. Blend again until a uniform batter forms. If using maple syrup, chocolate chips, or nuts, pulse them in gently.
03 - Heat a nonstick skillet or griddle over medium heat. Lightly grease with cooking spray or a thin film of oil.
04 - Pour approximately ¼ cup of batter per pancake onto the skillet. Cook for 2 to 3 minutes until bubbles rise to the surface and the edges appear set.
05 - Carefully flip each pancake and cook an additional 1 to 2 minutes until golden brown and cooked through. Repeat with remaining batter and serve warm with toppings of your choice.
