01 - Combine the bananas, eggs, milk, and vanilla extract in a blender. Blend on medium speed until the mixture is completely smooth and no banana lumps remain.
02 - Add the rolled oats, protein powder, baking powder, cinnamon, and salt to the blender. Blend again until a thick, smooth batter forms, stopping to scrape down the sides as needed.
03 - Set a nonstick skillet or griddle over medium heat. Lightly brush the surface with coconut oil or butter, allowing it to melt and coat evenly.
04 - Pour approximately ¼ cup of batter per pancake onto the heated skillet. Cook for 2 to 3 minutes, watching for bubbles to rise across the surface and edges to appear set.
05 - Carefully flip each pancake with a spatula and cook for another 1 to 2 minutes until the underside is golden brown and the center is cooked through.
06 - Transfer the pancakes to warm plates and serve immediately with fresh fruit, yogurt, or a light drizzle of pure maple syrup.
