Pie Filling Cake

1 can fruit pie filling (I've tried cherry and blackberry and love both)
1 box yellow cake mix
1 cube butter

1. Grease and flour 9x9 square pan.
2. Pour in one can pie filling
3. Dump in powder cake mix (don't prepare it...you just need the powder)
4. Melt 1 cube butter and pour it on top of the pie filling and cake mix.
5. Bake at 425* for 20 min.

This is really easy and very yummy. It kind of tasted like cobbler.
