Add bananas to a bowl with the rest of the ingredients except the butter. Gently stir together.
Warm a nonstick or cast iron skillet over medium heat. Add a small bit of the butter, melt, and spread it around the pan.
Drop 1/4 cup fulls of batter onto the pan and spread out thinly to about 1/4-1/2 inch think. Cook for about 3 minutes or until you see bubbles on the surface on the pancake. Flip and cook for an additional 2-3 minutes.
