Coat a medium nonstick skillet with cooking spray; heat over medium heat. Ladle 1/3 cup batter into the center of the pan. Immediately tilt and rotate the pan to spread the batter evenly over the bottom. Cook until the underside is golden brown, 1 1/2 to 2 minutes. Using a heatproof silicone or rubber spatula, lift the edge, then quickly grab the pancake with your fingers and flip it over. Cook until the second side is golden brown, about 1 minute more. Slide onto a plate. Repeat with the remaining batter, spraying the pan as needed and stacking pancakes as you go, to make 8 pancakes total.
