Preheat waffle iron. Spray with non stick cooking spray or brush with melted butter.Beat the egg in a bowl until fluffy. Add the milk, vanilla, melted butter, and sugar and mix well.
Whisk in the flour, baking powder, and salt and mix gently until combined. Do not overmix.
Pour the batter on the iron and close it. Depending on the size of your waffle maker, you might have too much batter. If so, use the little bit of remaining batter to make a second, smaller waffle.
Cook the waffle until no more steam comes out. The waffle should be golden brown and crisp.
Lift the waffle out of the waffle iron with a pair of tongs and enjoy right away.

Expert Tips
Consult Your Manual: Always start by reading your waffle maker's instructions, as models vary in cooking times and techniques.
Preheat Well: Ensure your waffle iron is fully preheated for that crave-worthy golden crust.
Mix Mindfully: Resist the urge to overmix your batter; it's okay to leave a few lumps.
Oil It Up: A quick swipe of oil on the iron ensures your waffle slides right off.
Steam is Key: Wait for the steam to stop rising from the waffle maker for a waffle that's cooked but still moist.
Mind Your Size: This recipe is tailored for a Belgian waffle maker, which may differ in size from yours. Any leftover batter can go towards a smaller, bonus waffle.
