"Blueberry Addie" (named after my daughter).
Need:
*two cans blueberry pie filling (apple/peach also work well).
*one box white cake mix
*one stick of butter
*larger size rectangular glass baking dish.
Lube the baking dish with PAM or something. Spread the pie filling evenly over the bottom of the dish.
Put the cake mix into a bowl and keep 'cutting' the butter in until it all looks kind of chunky. Before the next step, eat a bunch of it while no one's looking.
Put the cake+butter mixture (or what's left of it) on top of the pie filling and spread evenly.
I don't have the recipe here at work, but I think it's something like bake 20 minutes at 350, or until the cake mix on top looks golden - and the filling may be bubbling thru here and there.
Serve warm if possible, and of course it's extra good with some ice cream on the side!
Easy, fast, and mighty tasty.
