Preheat waffle iron. Spray with non-stick cooking spray right before pouring batter inside.
In a large bowl, combine flour, white sugar, baking powder, and salt.
Use the back of a spoon to create a well in the center. Set aside.
In a small bowl, whisk together eggs and milk. Add in butter and vanilla bean paste/extract and whisk to combine.
Pour wet ingredients into the well of the flour mixture and whisk until blended. Be careful not to overmix, as the batter should be lumpy.
