Have you ever made a Dump Cake? Basically you take a couple of cans of fruit, a boxed cake mix, butter, dump it all together and bake it. This makes a quick and easy cobbler-like cake. The recipe link I'm sharing uses cherry pie filling. I've made this with peaches and also with apples. I like to add just a bit of cinnamon to the cake mix to just bring out the flavors. I even made a chocolate-cherry version once using chocolate cake mix along with cherry pie filling and chocolate chips.
Check out this link to the Pioneer Woman Cooks - Dump Cake. Be sure to check out the great comments to her post. There are some wonderful ideas for different versions of this cake.
