White cake: changing it up

I like to grab a box cake mix out of the pantry a couple times a month and whip it up for the kids. Add a couple eggs, some water and oil and it's in the oven - quick and easy. However, I'm not a big fan of store bought frosting. It's usually too sweet for my taste.  I decided to switch things up last time. My white cake mix from a box got a layer of chocolate pudding on top then a layer of Cool Whip. Then the whole thing got sprinkled with Oreo cookie crumbs. And it got a thumbs up from the kids.
