Technically, a dump cake, but I prefer to call it a magic dessert. This easy recipe is made with pie filling, caramel sauce, doctored cake mix and butter.
Preheat oven to 350°F. Spray an 9-inch square baking pan with cooking spray.
Spread apple pie filling on the bottom of baking pan. Pour caramel sauce evenly over top.
In a large mixing bowl, stir together cake mix, apple pie spice and walnuts. Add in ½ cup butter and stir until crumbly. Pour mixture on top of apple pie filling.
Slice remaining butter into 1 inch long pieces. Place evenly on top of mixture.
Bake for 1 hour or until top is golden brown and a toothpick comes out clean. Let cool at room temperature for 15 minutes before serving. Add a dollop of whipped cream on top of each piece if desired.
