On a heavily floured surface, roll out the dough until it is 1/4-inch thick. Use a pizza slicer or knife to cut the dough into 2 1/2-inch square pieces and fry 3 to 4 pieces at a time in the oil. Immediately after dropping the dough into the oil use a large spoon to gently splash hot oil over the top of each piece. after 30 to 45 seconds, flip all of the beignets over and continue to baste with the oil. After another minute or so, flip the beignets again, and continue to cook until the beignets are a deep golden brown. Continue flipping the beignets over to brown them evenly on both sides. After about 3 minutes, they should be done. Let them drain on a cooling rack or a paper towel-lined plate for a minute, until you can handle them.
