Spray 6- to 7-inch skillet or crepe pan with cooking spray or grease lightly with butter; heat over medium heat. For each crepe, pour about 2 tablespoons batter into skillet. Immediately tilt and rotate skillet so thin layer of batter covers bottom. Cook until light brown. Run wide spatula around edge to loosen; turn and cook other side until light brown. Repeat with remaining batter, greasing skillet as needed.
