In a large saucepan, preheat oil to 350°F. Prepare a cookie sheet with paper towel to drain doughnuts as they come out of the hot oil.
Mix all dry ingredients followed by all wet ingredients until well combined.
Scoop small amounts of dough into the oil. You can use a small ice cream scoop to make them uniform. Add 4-5 pieces at a time and fry until golden brown, about 7 minutes. Make sure you keep an eye on the temperature, if oil is too hot, doughnuts will turn golden brown but the center may still be raw. Remove from oil and drain in paper towel. Repeat until done will all the dough.
While still hot, toss doughnuts with sugar and serve.
