Remove donuts from oil, and move to the wire rack. Once the donuts are removed from the oil let rest on the wire rack for about a minute, then dip each donut in the cinnamon sugar. Move back to the wire rack. Repeat with the remaining donuts and donut holes, frying them first, then coating in the cinnamon sugar. Keep an eye on the donut holes as they may fry faster. Let cool slightly but serve warm!
I use pumpkin pie spice blend in this recipe because it has a mix of spices like cinnamon, ginger and nutmeg that really play up the apple flavor. You can use my recipe for homemade pumpkin spice blend to make some yourself or just use a store bought mix. Or just use the same amount of plain ground cinnamon instead!
