Once the pan is hot, coat the bottom with a small pat of butter. Pour enough batter to cover the bottom of the pan (about 3 T for a 6-inch pan.) Cook until the top is set, then flip and cook the other side briefly. Once you flip the pancake you will notice it puff up a bit, and seem to "grow" up the sides of the pan. When it stops "growing" it is done. Ideally you don't want the pancake to brown at all, so adjust your heat as needed. (It's okay if they get a little brown, so don't worry if they do!)
