Gather all ingredients at room temperature.

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

In another bowl, mix the milk, eggs, melted butter, and vanilla until smooth.

Combine wet and dry mixtures; stir gently until just combined (lumps are okay).

Preheat your waffle iron according to instructions.

Pour batter onto the hot iron (about 1/2 cup), close it, and cook until golden brown (4-5 minutes).

Serve with syrup or fresh fruit.
