Coat a 6-inch skilled with nonstick cooking spray. Heat over medium heat; remove from heat. Spoon 2 tablespoons batter into skillet, tilting skillet to spread batter evenly. Return to heat; brown on one side only (1 to 2 minutes). Invert pan over paper towels; remove crepe from pan. Repeat with remaining batter.
