Preheat oven to 325 degree F. Line a 9x13-inch rimmed baking sheet with aluminum foil and lightly coat with cooking spray.

In a large bowl, beat together butter, sugar, and powdered sugar. Add 2 1/2 teaspoons vanilla and beat until combined. Mix in flour and cinnamon to form a soft dough.

Press 2/3 of the dough into the bottom of the lined baking sheet and place the rest of the dough in the refrigerator. Bake 15 minutes.

Meanwhile, place the caramels, cream, and 1/2 teaspoon vanilla in a medium bowl. Microwave on high, stirring every 30 seconds, until caramels are melted, about 3 minutes. Stir in the apples.

Remove the crust from the oven and spread the caramel apple mixture evenly over the top. Crumble the remaining dough on top of the caramel. Return to the oven and bake another 25 minutes or until filling is bubbly. Remove from oven and let the bars cools completely.
