Blend the Oats. Start by blending the rolled oats in a blender or food processor until they form a fine flour. This step ensures a smooth pancake batter.
Prepare the Batter. In a large bowl, mash the bananas until smooth. Add the eggs, milk, vanilla extract, and cinnamon. Mix well to combine.
Combine Ingredients. Gradually add the oat flour and baking powder to the wet mixture. Stir until just combined, being careful not to overmix.
Cook the Pancakes. Heat a non-stick skillet or griddle over medium heat. Lightly grease with a small amount of oil or butter. Pour 1/4 cup of batter for each pancake. Cook until bubbles form on the surface, then flip and cook until golden brown on both sides.
Serve. Top your pancakes with maple syrup, sliced bananas, and a sprinkle of nuts. Enjoy them warm!
