Preheat your waffle iron to a medium-high setting, around 375°F (190°C).

In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt until combined.

In another bowl, beat the eggs, and stir in the warm milk, melted butter, and vanilla extract.

Pour the wet mixture into the dry ingredients and fold gently until just combined.

Lightly spray the preheated waffle iron with non-stick cooking spray or brush with melted butter.

Ladle about ¾ cup of batter into the center of the waffle iron and cook according to instructions for 4-5 minutes or until golden brown.

Remove the waffles and place them on a wire rack to keep them warm and crisp.

Serve warm with toppings of your choice like butter, maple syrup, or fresh fruit.
