Preheat oven to 350 degrees, and spray 2 non-stick six unit doughnut pans. In one bowl whisk together all of the dry donut ingredients, in another bowl whisk together all of the wet ingredients. Pour the wet ingredients into the dry ingredients, and stir together until combined. Spoon batter into prepared pans, filling about ¾ full. Bake 12-14 minutes, or until toothpick inserted in center comes out clean. While baking prepare spiced sugar. Cool in pan for about 5 minutes, remove and generously dust donuts, both sides, with spiced sugar. Serve warm.
