Separate dough into individual biscuits.

Flatten each biscuit dough with the palm of your hands; cut in half.

Place 0.5 teaspoon of jelly in the middle of each half.

Form each biscuit into a ball by pinching together the ends and then rolling the dough in between your palms.

Fill a saucepan about 1/3 way up with oil; heat oil.

Once the oil is hot, lower the heat to medium-low. That's about a "3" on a gas stove.

Drop the doughnuts into the saucepan, 2 to 3 at a time.

Fry them for 1 to 2 minutes or until golden, and then flip with tongs to fry the other side.

Combine the sugar and cinnamon in a small bowl; toss the doughnuts in the cinnamon-sugar mixture while they're still warm.

Serve immediately.
