01 - Place the bananas, eggs, almond 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, cinnamon, and salt to the blender. Blend again until a uniform batter forms. If using maple syrup, chocolate chips, or nuts, pulse them in briefly to distribute evenly without overmixing.
03 - Heat a nonstick skillet or griddle over medium heat. Lightly coat the surface with cooking spray or a thin film of oil, allowing it to warm for about 1 minute.
04 - Pour approximately 1/4 cup of batter per pancake onto the hot skillet, spacing them about 2 inches apart. Cook for 2 to 3 minutes until bubbles rise across the surface and the edges appear set. Carefully flip each pancake and cook an additional 1 to 2 minutes until the underside is golden brown and the center is cooked through.
05 - Transfer the finished pancakes to a warm plate and repeat with the remaining batter. Serve immediately with desired toppings such as sliced banana, fresh berries, nut butter, or a drizzle of maple syrup.
