Preheat oven to 400°F. Bring crusts to room temperature according to package directions. Unroll pie crusts. Press 2 of the pie crusts onto bottom and sides of 13x9-inch glass baking dish. Press seams of overlapping crusts in middle of baking dish together to seal.
Mix sugar, cornstarch and cinnamon in large bowl. Add apples; toss to coat well. Spoon into pie crust. Drizzle with 3/4 cup of the caramel topping. Top with remaining 2 crusts. Pinch edges of top and bottom crusts together to seal. Cut small slits in top crust.
Bake 35 to 40 minutes or until crust is golden brown and filling is bubbly. Cool on wire rack. Drizzle with remaining 1/4 cup caramel topping to serve.
