Preheat your waffle iron until it’s hot and ready.
In a bowl, whisk together flour, sugar, baking powder, and salt.
In another bowl, beat the eggs, then add milk, melted butter, and vanilla.
Pour wet ingredients into dry and stir until just combined. Don’t overmix—lumps are fine.
Scoop batter into the waffle iron and cook until golden brown and crisp.
Serve warm with syrup, fruit, or anything that makes you smile.
