In small saucepan, combine 1/2 cup applesauce, milk and 1/4 cup butter; cook over medium heat until very warm (120 to 130ºF.), stirring constantly. Add warm mixture and egg to flour mixture; blend at low speed until moistened. Beat 2 minutes at medium speed. By hand, stir in 1 1/2 to 1 3/4 cups flour until dough pulls cleanly away from sides of bowl.
