Heat vegetable oil in a saucepan to 375 degrees F. Open up the can of biscuits, separate them from one another. With a one-inch round cutter, cut a hole into the center of each biscuit. Add biscuits and holes into the oil a couple at a time. When they turn golden brown, remove, drain on paper towels and roll into cinnamon and sugar mixture. For the cinnamon and sugar mixture, simply combine the two on in a bowl or lipped plate.
