my first time making them, so you can avoid the same mistakes:
1 Can refrigerated biscuit dough
4 Tbsp powdered sugar
1 Tbsp apple juice
Cinnamon and sugar
Unroll package of biscuit dough, cut center circle out of each biscuit using biscuit cutter or any other round cutter. Heat oil in a skillet (enough to cover biscuit about halfway). Drop in donut and donut holes for about 30sec - 1min or until browned, then turn and brown on other side (tip: don't get the oil so hot it browns them faster than this on each side - see what happens). Remove and place on tray lined with paper towels to drain. Once cooled, but still warm, cover with glaze or sugar.
Stir 4 Tbsp powdered sugar with 1 Tbsp apple juice until sugar is dissolved and looks smooth and shiny. Pour over donuts on cookie rack on top of baking sheet to catch the drippings.
