Combine sugar and cinnamon in a small bowl. Set aside.

Line a plate with paper towels and set aside. Have a second plate or serving tray ready for the cinnamon sugar dusted donut holes.

Place your frying oil in a dutch oven over medium heat. Use a candy thermometer to ensure you bring the oil to 350F.

Cut each biscuit with a small circular cookie cutter, then shape similarly sized balls of dough with the remaining biscuit dough.

Once oil is hot, fry donut holes in groups of 5 or 6 for about 1 minute per side, until golden brown.

Set fried donut holes on the paper towel lined plate for a minute, then while still warm, transfer to the bowl with cinnamon sugar and swirl to coat. Remove to a separate plate.

Once all donut holes have been fried, turn off the heat for the oil.
