Lightly oil a large nonstick skillet and heat over medium heat. Using 2 tablespoons of batter for each pancake, drop 4 mounds of batter into the pan. Cook until bubbles appear on the surface and the edges look dry, 2 to 4 minutes. Using a thin spatula, gently flip the pancakes and cook until browned on the bottom, 1 to 2 minutes more. Transfer the pancakes to a plate. Lightly oil the pan again and repeat with the remaining batter.
