In a bowl, mash the ripe banana until smooth.
Add the rolled oats and milk to the mashed banana, stirring until combined.
In a separate bowl, whisk the egg and then add it to the banana-oat mixture.
Stir in the baking powder, vanilla extract, cinnamon, and salt.
Heat a non-stick skillet over medium heat and lightly grease it.
Pour 1/4 cup of batter onto the skillet for each pancake.
Cook for about 2-3 minutes or until bubbles form on the surface.
Flip the pancakes and cook for another 2-3 minutes until golden brown.
Remove from the skillet and keep warm while cooking the remaining batter.
Serve warm with your favorite toppings.
