My husband shared this recipe with me years ago, it's from his Boy Scout days.
Preheat deep fryer to 375 degrees. Open biscuits, separate, place a hole in the center. You can use the holes for donut holes or roll them into a few large donuts.
Have an adult place the doughnuts in the deep fryer one at a time. As you see them browning on one side, carefully flip them over and let them brown on the other side. Once both sides are brown remove from oil and let cool on a paper towel, you can then coat the donuts (powder sugar, cinnamon & sugar, glaze, chocolate frosting...)
