1 can of pie filling (I usually use peach, but any will work)
1 cup frozen blueberries
1 cake mix (dry) (I usually use vanilla or yellow)
1 cup melted butter
In a 9x13 pan, layer ingredients in the order above. Bake 325 for 45 minutes. The original recipe calls for cherry pie filling with white cake mix. You can mix and match to make different creations.
