- Lightly coat an electric pizzelle iron with oil; heat according to the manufacturer's directions. (Or coat a nonelectric pizzelle iron with oil; heat on range top over medium heat until a drop of water sizzles on the surface. Reduce heat to medium-low.)
- For each pizzelle, place 1 slightly rounded tablespoon of batter on pizzelle iron, slightly off-center toward the back. Close lid; bake according to the manufacturer's directions. (If using a nonelectric iron, bake about 2 minutes or until light brown, turning once.) Transfer warm pizzelles to a wire rack; cool. If desired, sprinkle pizzelles with powdered sugar.
