Preheat oven to 350° F. Spray a 9 x 13 casserole dish with nonstick spray.
Add cherry pie filling to the bottom of the dish and gently spread.
Sprinkle cake mix over fruit mixture. Using a spatula gently incorporate the cherry juice into the cake mix to moisten it.
Evenly distribute butter pads to the top of the cake.
Place dump cake into the oven uncovered and bake for 55-60 minutes. The cake will become a deep golden brown once done and will look crispy on top with a fluffy inner. Allow to cool for 15 minutes before serving warm.
