In a mixing bowl, combine the rolled oats, baking powder, baking soda, and salt.

In another bowl, mash the ripe bananas and then add milk, egg, and vanilla extract. Mix well.

Pour the wet ingredients into the dry ingredients and stir until just combined.

Heat a griddle or frying pan over medium heat and grease with butter or oil.

Pour 1/4 cup of batter onto the pan for each pancake.

Cook until bubbles form on the surface, then flip and cook until golden brown on the other side.

Repeat with remaining batter, greasing the pan as needed.

Serve warm with your favorite toppings such as maple syrup, fresh fruit, or yogurt.
