In a small bowl, combine sugar and cinnamon; set aside.
Make batter, following steps 1 through 3 in the buttermilk waffles recipe.
Ladle 1/3 cup batter onto each square of the waffle grid; spread almost to the edges. Sprinkle with 1 to 2 teaspoons cinnamon sugar.
Close lid; bake 3 to 5 minutes, until no steam emerges from waffle iron. Transfer to a baking sheet; place in an oven set to low heat, about 200 degrees, while using remaining batter. Serve warm.
This was one of the very first recipes I ever made when I was a newly wed over ten years ago. I just made it again this morning. They are delicious and completely worth the extra step of beating the egg whites. They're light, fluffy, homey, and rustic all at the same time.
I made the batter. My husband made the waffles. He said they are the best waffles he ever had! He is a HUGE fan of cinnamon and sugar. I think I scored some points with this recipe. :-)
