Add enough oil to a deep fryer or large, deep heavy pot so that it is a couple of inches deep.
Heat the oil to 350 degrees.
Place 2 to 3 biscuits in the oil and allow them to lightly brown on one side, about 90 seconds. Be sure to fry only a couple at a time or the oil may cool too much and the donuts will absorb too much oil.
Turn the biscuits over to brown on the other side.
When the donuts are golden brown on both sides, transfer them to a wire rack or paper towels to drain for 15 seconds.
