Preheat oven to 300°F. In a large mixing bowl, mix flour, oats, salt, soda, cinnamon, cloves and lemon zest. Mix well; add butter, sugar, egg, apple sauce and maple syrup. Mix until well blended. Add fresh chopped apples and caramel chips. Mix until all ingredients are combined. Do not over mix. Dough will be soft. Drop by rounded tablespoon-full onto greased cookie sheet about 2 inches apart. Bake 12-15 minutes until bottoms are golden. Mix powered sugar, milk and maple flavoring in small bowl until smooth. While cookies are still warm, ice with maple icing and let set.
