Sift first 4 ingredients into bowl and make a well in center. Combine egg yolks with remaining ingredients in bowl, beating well. Beat egg whites until stiff, but not dry. Pour banana mixture into dry ingredients, stirring until just mixed. Fold in egg whites until barely blended. Bake in waffle iron using appliance directions.
Sounds good...I make banana pancakes a lot and waffles would be a nice change. In my pancake recipe I change it up by grinding up oatmeal in place of at least half the flour. I'll have to try it out on my waffle maker.
