01 - In a large bowl, mash the ripe bananas thoroughly using a fork until smooth. Add the eggs and vanilla extract, then whisk until completely combined.
02 - Stir in the rolled oats and baking powder until the mixture forms a uniform batter. Allow the batter to rest for 2 minutes to hydrate the oats.
03 - Heat a non-stick skillet over medium heat and lightly grease with butter or oil. Pour approximately 2 tablespoons of batter per pancake into the pan. Cook for 2 to 3 minutes on the first side until bubbles form and the edges begin to set, then flip and cook for 1 to 2 minutes until golden brown. Repeat with remaining batter.
