In a blender or food processor, combine the ripe banana (broken into chunks), rolled oats, eggs, milk, vanilla extract, baking powder, cinnamon, and salt.
Blend the ingredients until smooth and well combined, creating the pancake batter.
Heat a non-stick skillet or griddle over medium heat and lightly grease with butter or oil.
Pour about 1/4 cup of pancake batter onto the skillet for each pancake, spreading it out slightly with the back of a spoon.
Cook the pancakes for 2-3 minutes on one side, or until bubbles form on the surface.
Flip the pancakes and cook for an additional 1-2 minutes on the other side, or until golden brown and cooked through.
Repeat with the remaining batter, adding more butter or oil to the skillet as needed.
Top the pancakes with sliced bananas, pecans, and maple syrup. Serve with milk.
