First off, I must warn you this cake is extremely good, you will want bowl after bowl, and it is extremely easy to make.
So how do you make this delicious heavenly dessert? First, you will need a 21oz can of pie filling, I used blueberries and cream, I also added more blueberries because I felt the filling didn't have enough. I recommend using frozen blueberries, but I'm sure fresh would also work, you also will need a box of yellow cake mix, and one stick or in my case 8 tablespoons of butter or margarine. (I told you it's all so simple.)
Next you will want to oil or spray your pan with non-stick spray. I used a 9x13 inch pan. Then, open your can of pie filling and spread evenly on the bottom of your pan. This is when I then topped with extra blueberries. Your pan will then look like the picture below.
Now, open your dry cake mix and spread evenly over this blueberry mixture, then either cut up the stick of butter or measure out 8 tablespoons and distribute throughout the top of the cake mixture.
Once you have finished this step put your pan in the oven and bake for about one hour and ten minutes or until baked enough to your liking.
Again I warn you, after you have your first bowl you will be coming back for seconds.
