Mix the dry ingredients in a bowl, set aside.
Take the eggs and beat them until frothy and light. I use a mixer to do this and once the eggs can create a peak I add the milk. Mix well, add butter and vanilla. Gradually add in the dry ingredients until well blended.
Using your waffle maker, spray with cooking spray. Once waffle maker is ready pour batter and cook to your waffle makers instruction.
I use a ladle to spoon batter, it seems to be the easiest way to evenly get the waffle to hit the edges.
