I have made donuts at home a number of times, but more often I have done it camping. Buy cheap canned biscuits and punch a hole out of the middle. Next, place them in hot oil. Canola oil is usually the cheapest. As one side gets brown, flip over to the other side. The donut holes can easily also be cooked, and they often flip themselves. In order to make a basic glaze icing, take powdered sugar and water mixed together.
