In a small bowl, combine cranberry sauce and orange zest; set aside.
In a large bowl, combine the flour, sugar, cinnamon, baking soda, baking powder, and salt. Beat the egg, milk and oil; stir into dry ingredients just until moistened. Fold in apple.
Fill greased or paper-lined muffin cups half full. Make a well in the center of each muffin; fill with about 2 teaspoons of reserved cranberry mixture.
Bake at 375 degrees for 18 to 20 minutes or until a toothpick inserted in muffin comes out clean. Cool for 5 minutes before removing from pan to a wire rack.
