Heat about 2-3 inches of vegetable oil in a heavy-bottomed saucepan to 350°F (175°C).

In a medium bowl, mix together granulated sugar and ground cinnamon; set aside.

Flatten each refrigerated biscuit into a 4-inch round using your hands or a rolling pin.

Place a tablespoon of apple pie filling and half a caramel candy in the center of each dough round.

Pinch the edges of the dough together tightly to form a ball.

Carefully lower the sealed balls into the hot oil and fry for 3-4 minutes until golden brown.

Remove fried bombs and drain on paper towels, then roll in the cinnamon sugar mixture.

Let the bombs cool slightly before serving.
