In Papa's Donuteria, you'll need to fry the donuts before you add any toppings. The key to frying perfect donuts is to maintain a consistent oil temperature. If the oil is too hot, the donuts will cook too quickly on the outside and be raw in the middle. If the oil is not hot enough, the donuts will absorb too much oil and be greasy.
To get started, heat your oil to 350 degrees Fahrenheit. While it's heating up, cut out your donut shapes from dough using a biscuit cutter or a glass with a wide mouth. Once your doughnuts are cut out, use a fork to poke two holes in each one - this will help them cook evenly inside and out.
When your oil is ready, carefully lower 2-3 doughnuts into the fryer using a slotted spoon or spatula. Fry for about 60 seconds per side, or until they're golden brown all over. As they finish cooking, remove them from the fryer and place them on a paper towel-lined plate to cool slightly.
Once they're cool enough to handle, dip each doughnut in your favorite glaze or icing. Be sure to evenly coat both sides of each doughnut! Allow the glazed doughnuts to set on a wire rack before serving warm (or enjoy at room temperature).
