In a large bowl, whisk together the flour, sugar, baking powder, and salt.
In another bowl, beat the eggs and then add milk, melted butter, and vanilla extract.
Pour the wet ingredients into the dry ingredients and stir until just combined.
Lightly grease the waffle iron with nonstick spray or butter.
Pour the batter onto the waffle iron and cook according to the manufacturer’s instructions until golden brown.
