Spray a griddle pan with cooking spray or melt 1 tablespoon butter over medium heat. If desired, preheat the oven to 200 degrees F to keep the pancakes warm. Once the pan is hot, spray 3-inch circles of pancake batter on the pan, working in batches. If you are adding anything to the batter, now is the time to do it. Cook the pancakes over medium heat for 2 minutes or until slightly bubbly and the edges begin to dry. Turn and cook for an additional minute. Keep warm in the oven on an oven safe plate while you repeat the above steps with the remaining batter.
