Separate dough into individual biscuits.

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

Place 1/2 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 a 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 my gas stove.

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

Fry them in the oil until golden and then flip with tongs to fry the other side.

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

Serve immediately.
