Place the oil in a large, deep skillet or a deep pan, but don’t heat it yet.
Prep your work space by grabbing a slotted spoon or tool for flipping and fishing your donuts out of the oil. Place paper towels under a wire rack near your frying surface — this is where you’ll put the doughnuts to cool off.
5. Fry
Heat your oil to 350 F. Transfer the dough, a few at a time, into the hot oil and fry until browned, about 1 minute. Flip and fry the other side. Using a slotted spoon, remove from the oil and transfer to the wire rack. Continue frying until all are done.
Pro Tip: The second side takes less time to fry, so pay close attention.
