In a bowl, mash the ripe banana until smooth.
Add rolled oats, milk, egg, baking powder, vanilla extract, and salt to the bowl.
Mix until well combined; let the batter sit for 5 minutes to thicken.
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 2-3 minutes until bubbles form on the surface.
Flip the pancakes and cook for another 2-3 minutes until golden brown.
Repeat with remaining batter, adjusting heat as necessary.
Serve warm, topped with yogurt, fresh berries, or maple syrup.
Enjoy your delicious banana oatmeal pancakes!
