Using a food processor, process the oats into a coarse flour. Mix the oats, whole wheat flour, salt, baking powder, and baking soda together in a mixing bowl.
In a separate bowl whisk together eggs, mashed bananas, and milk.
Add the egg mixture into the flour. Stir until just moist. You want the pancakes to have a nice consistency that will hold a shape. If the batter is too thin add up to 1 cup total of whole wheat flour.
Cook on a griddle pre-heated to 350 degrees. Adjust temperature as necessary.
