Pour about 2 inches of oil into a deep pot and heat to 350°F.

Press each biscuit into a flat circle, about 3 inches wide.

Place one marshmallow and one piece of chocolate in the center. Fold up the dough and pinch it closed to make a ball.

In a bowl, stir together crushed graham crackers, sugar, and cinnamon.

Fry 3–4 dough balls at a time for 2–3 minutes, turning until golden.

Take them out with a slotted spoon and roll in the graham sugar mix right away.

Let cool slightly on paper towels. Drizzle with chocolate sauce and enjoy.
