In a blender, combine the rolled oats, protein powder, baking powder, and salt. Blend until fine.
Add the banana, eggs, milk, and vanilla extract to the blender.
Blend until the mixture is smooth and well combined.
Heat a non-stick skillet over medium heat and lightly grease it.
Pour about 1/4 cup of batter onto the skillet for each pancake.
Cook until bubbles form on the surface, about 2-3 minutes.
Flip the pancakes and cook for another 2-3 minutes until golden brown.
Repeat with the remaining batter, greasing the skillet as needed.
Serve warm with your choice of toppings.
Enjoy your delicious protein-packed pancakes!
