Apple Dump Cake

Two cans of apple pie filling, yellow cake mix, lots of butter and pecans with a few other ingredients in a 9 X 13" pan. I wanted a dessert for the adults to go along with the ice cream sundaes at a potluck and it was very popular, with the vanilla ice cream on top. I will make this again for a pot luck dessert when I don't have time for measuring and chopping. I found I could use my cheese slicer the long ways on the sticks of butter to quickly cut thin slices to cover the dry cake mix.
