An apple cider reduction and plenty of warming spices transform a batch of cake donuts into everyone's favorite fall treat. They're rolled in cinnamon sugar for good measure.
If you want to make all donut holes, flatten dough to 3/4 to 1 inch thick. Use a floured 1 1/2-inch cutter to cut out about 42 rounds. Cook, flipping a few times, until deep golden brown all over, 2 1/2 to 3 1/2 minutes total.
