Bring apple cider to a boil then simmer until reduced by half, about 20 minutes. Let cool completely.
Cream the butter and add sugar.
Add eggs and vanilla. Mix.
Add the cooled cider. Mix thoroughly.
Add all of the spices. Mix.
Add 3 1/2 cups of flour, baking powder and baking soda. Slowly stir together and add more flour if too sticky. Knead dough for 5 minutes.
Heat oil to 350F.
Meanwhile, roll dough to 1/2 inch thickness. Cut with 1 inch circle cutters.
Mix together 1/2 cup sugar and 1 tablespoon cinnamon in a small bowl and set aside next to a papertowel lined plate. This will be for after you pull the donuts from frying.
Gently drop 5-6 donuts into the hot oil and let fry until golden and floating (about one minute). Flip over with tongs and cook another minute before pulling and resting on the papertowel lined plate. Place 5-6 more donut holes in the oil. While the second batch fries, roll the first batch in the cinnamon sugar mixture to coat. Set aside. Repeat until all the donut holes are cooked.
