In a large, heavy sauce pan, preheat 3–4 inches of vegetable oil to 350°(F).
While the oil is heating, on a lightly floured surface, using a rolling pin, roll each biscuit 4–5 inches in diameter.
Place a heaping tablespoon of pie filling in the center of each biscuit. Fold the biscuit over, using a fork, crimp the edges together. Place each prepared pie on a parchment-lined baking sheet.
In a bowl, or shallow pie plate, combine the sugar and cinnamon. Mix until well blended. Set aside until ready to use.
Check the temperature of the oil with a thermometer. If the oil has reached 350°(F), carefully place one prepared pie into the hot oil. Fry 1–2 hand pies at a time. Cook for 2–3 minutes until golden brown. Flip and cook the other side until golden brown.
Using a slotted spoon, carefully remove the fried hand pie and place on a paper towel-lined plate or baking sheet. After slightly cooled, roll the pie in cinnamon sugar, or sprinkle with powdered sugar and serve.
