01 - Place the ripe bananas, eggs, milk, and vanilla extract into 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, ground cinnamon, and salt to the blender. Blend again until a thick, smooth batter forms, scraping down the sides as needed.
03 - Heat a nonstick skillet over medium heat and lightly brush the surface with coconut oil or butter, allowing it to melt and coat evenly.
04 - Pour approximately 1/4 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 an additional 1 to 2 minutes until the underside is golden brown and the center is cooked through.
06 - Transfer the pancakes to a plate and serve warm. Garnish with fresh fruit, a dollop of yogurt, or a drizzle of maple syrup as desired.
