Heat oven to 425°F. Unroll crust on work surface. Roll crust out slightly; cut into 4 (5-inch) rounds. Place rounds on parchment lined cookie sheet.
In medium bowl, mix sugar and cinnamon; toss apple slices into sugar mixture. Divide apple slices evenly onto center of each pie crust round. Fold 1/2-inch of crust over filling, pinching slightly so that crust lays flat on apples.
Bake 18 to 20 minutes or until crust is golden brown and apples slices are tender. Drizzle 2 teaspoons caramel topping over each crostata. If desired, serve warm with ice cream.
