Preheat oil in a frying pan enough to cover half the biscuit when placed in the pan. Open the can and separate the biscuits. Poke a hole in the center of each biscuit, I use a soda bottle cap it works well. Fry biscuits about 2 minutes on each side. Drain on paper towels. You can roll them in just about anything like sugar, cinnamon, powdered sugar, or you can frost them with icing.
When my daughter had a sleepover with her friends in the morning we cooked these and everyone got to help. They loved getting to roll their doughnuts in whatever they wanted and they even helped poking out the middles of them. It was a big hit with the kids.
