10-minute Doughnuts








Pillsbury biscuit dough


cooking oil (enough to float the dough on)


sugar


metal bottle cap (for making holes)








Directions: Warm the cooking oil in a deep frying pan. Fashion the biscuit dough into nice doughy blobs. Cut out dough nut holes with bottle cap. Place dough into pan then immediately begin to flip them over with a spatula or other flipping instrument of your choice. Once the dough is a light golden brown, remove them from the pan. If you want, pour a small amount of sugar into a ziplock bag, along with a dough nut and shake until dough nut is covered.How much oil should be in a pan for making doughnuts?
I use at least 3 inches of oil, because when it drops in you don't want it sticking to the bottom.
