Preheat oven to 350°F. Grease a donut pan well.
Simmer the ½ cup apple cider until it reduces to about ¼ cup. This intensifies the apple flavor. Let it cool for a few minutes.
In a large bowl, combine: Spice cake mix, ½ cup applesauce, Reduced apple cider, Eggs, Melted butter, Vanilla
Mix just until combined.
Fill the donut cavities about ⅔ full.
Bake for 12–15 minutes, or until the donuts spring back when lightly touched.
Cool for 5 minutes before removing from the pan.
Brush cooled donuts with melted butter then dip into cinnamon and sugar mix and enjoy!!
