Chocolate Waffles
1 1/2 cups flour
1/4 cup cocoa
1 teaspoon baking powder
1 teaspoon baking soda
1/3 cup sugar
2 cups buttermilk
1/2 cup butter, melted
2 large eggs, separated
1 teaspoon vanilla
A pinch of cream of tartar
Sift together flour, cocoa, baking powder, baking soda and sugar into a bowl and make a well in the center of the dry ingredients.
In a separate bowl, mix buttermilk, egg yolks and vanilla, then pour into the dry ingredients and combine.
Beat egg whites with cream of tartar in a separate bowl until soft peaks form. Gradually fold the beaten whites into the batter, 1/3 at a time.
Prepare waffles following directions for your waffle iron. If you like, serve with vanilla ice cream on top.
