First, add the cans of cherry pie filling to the bottom of a baking dish and smooth out.
Now sprinkle the cake mix as evenly as you can over the cherry pie filling. Using the back of a spoon, spread it out evenly.
Then pour the butter over the cake mix. Lift the baking dish and tilt it around until the butter spreads evenly on top of all of the cake mix.
Next, place the baking dish into the oven and bake at 350 degrees for about 40 minutes or until the cake is cooked all the way through and the sides are hot and bubbly.
Finally, let it cool slightly before serving and enjoy!
