Preheat the oven to 350°F, and grease a 9x13-inch cake pan.
In a medium bowl, combine the apple pie filling and apple pie spice. Transfer the filling to the pan, and spread into an even layer.
40 ounces apple pie filling, 2 teaspoons apple pie spice
In a separate small bowl, microwave the caramel bits and heavy cream for 15-20 seconds at a time until smooth. Drizzle the caramel sauce over the pie filling.
11 ounces caramel bits, 3 tablespoons heavy cream
Sprinkle the dry cake mix over the caramel sauce. Then, arrange the pats of butter in an even layer over the top of the cake mix.
13.25 ounce box yellow cake mix, 1 cup unsalted butter
Bake for 40-50 minutes or until the top of the cake is golden brown and the filling bubbles around the edges.
Serve warm with vanilla ice cream and extra caramel sauce!
