Heat a medium nonstick frying pan over medium heat and brush the pan lightly with vegetable oil. Spoon about 1 tablespoon of the batter into the skillet and spread the batter into a round. Keep spooning to fill the skillet, leaving about an inch between each pancake, 4 to 5 pancakes per batch depending on the size of your pan. Cook until there are bubbles on the surface of the pancakes and the bottoms are browned, 1 to 2 minutes. Flip the pancakes and cook until the second side is browned, about 1 minute more.
