Here is another 2 ingredient recipe: (not good for the dieters)
Home Made Doughnuts
1 can of refrigerated biscuits (the cheap kind)
2 cups vegetable oil (more or less depending on the size of your
skillet)
Heat the vegetable oil in a skillet. Poke a hole in the center of each
biscuit. Place carefully in hot oil. Brown (approx. 1 min.) each side
of the biscuit. Remove from oil and roll in powdered sugar, cin. and
sugar or glaze if desired.
