Preheat the oven to 350ºF. Roll out the pie crust and place in a 9-inch pie plate, crimping the edges as desired. Spray a piece of foil with nonstick cooking spray and place, sprayed side down, in the crust, covering as much of the crust as possible. Fill the inside with pie weights or dried beans. Place the dish on a baking sheet, then place in the oven and bake for 20 minutes. Remove the crust from the oven and remove the foil and the weights. Set aside.

Turn the oven up to 375ºF.

Place the butter in a large skillet over medium-high heat. Add 1/2 cup of the brown sugar and stir until the butter is melted. Add the apples, cooking and stirring until the apples are tender and caramel in color, about 12 minutes. Drain the apples and set aside.

Meanwhile, in a double boiler or a bowl set over a pan of simmering water, combine the caramels and the half and half. Cook, stirring often, until the caramels are melted and smooth. Keep warm.

In a small bowl, beat the cream cheese and the remaining 1/2 cup brown sugar until light and fluffy. Add 1/2 teaspoon of the pumpkin pie spice, the vanilla, and the egg. Beat until completely combined.

In a small bowl, combine the chopped chocolate chips and chopped pecans.

Fold half of the caramel mixture into the cream cheese mixture. Fold the remaining caramel into the apples. Spoon the caramel apple mixture into the pie crust. Reserve 2 to 3 tablespoons of the chocolate chip mixture for the topping, and sprinkle the remaining mixture over the apples. Spoon the cream cheese mixture over the top.

Place the pie dish on a baking sheet and bake in the preheated oven for 35 to 45 minutes, or until the top is a deep golden brown and the filling is set. Cool completely.

In a bowl, beat the cream until it starts to thicken. Add the remaining 1 tablespoon of pumpkin pie spice. Continue to beat, gradually adding the powdered sugar, until the cream has soft peaks. Spread the whipped cream over the top of the pie. Sprinkle with the remaining chocolate chip and nut mixture.

Store the pie in the refrigerator.
