Waffles with Vanilla Sauce Recipe

In a bowl, combine flour, baking powder and salt. In another bowl, beat egg yolks lightly. Add 1-2/3 cups milk and oil; stir into dry ingredients just until moistened. Set aside 1/4 cup batter in a small bowl. Beat egg whites until stiff peaks form; fold into remaining batter. Bake in a preheated waffle iron according to manufacturer's directions until golden brown. In a saucepan, heat sugar and remaining milk until scalded. Stir a small amount into reserved batter; return all to pan. Bring to a boil; boil for 5-7 minutes or until thickened. Remove from the heat; add vanilla and mix well (sauce will thicken upon standing). Serve over waffles. Top with berries.
