Preheat waffle iron

In a large bowl mix together dry ingredients until well combined

I'm a medium bowl whisk together the egg yolks and buttermilk until well combined. Gradually whisk in the butter

Pour liquid ingredients into the dry ingredients and whisk gently until batter is evenly moistened. It's fine if there are lumps. It will be a thick batter

In a clean medium bowl, with a clean whisk, rotary beater, or handheld mixture, beat the egg whites until they hold soft peaks. Using a rubber spatula, slide the beaten whites onto the batter and gently fold them in.

Pour a generous .5 cup of batter into the center of the waffle iron. Use the rubber spatula to even out the batter. Close and Cooke till desired doneness.

Remove waffle and let cool then serve.
