Heat oven to 400° F. LIne 12 medium muffin cups with paper baking cups or spray bottoms only with cooking spray. In large bowl, combine flour, sugar, baking powder, cinnamon and salt; mix well. In medium bowl, combine applesauce, milk, oil and egg; blend well. Add all at once to dry ingredients; mix just until dry ingredients are moistened. (Do not over mix.) Fill muffin cups about two-thirds full. Bake 18 to 20 minutes or until golden brown and wooden pick inserted in center comes out with a few moist crumbs clingling to it. Cool muffins in pan on wire rack for 5 minutes; remove from pan. Serve warm.
