I made it for my daughter's Sweet Sixteen birthday. It was a HUGE hit with the girls. And I have to say it turned out looking pretty good--close to the photo I first shared on Pinterest.
Here's the original recipe on the Kraft website. (click here)
1 package Devil's Food Cake mix
4 squares bakers semi-sweet chocolate (I used chocolate chips)
1/4 cup butter
1 package cream cheese softened (I used the light version)
1/2 cup sugar
2 cups thawed Cool Whip (I forgot and used one whole container which was probably about 4 cups!)
12 Oreo cookies coarsely chopped or crushed
Preheat oven to 350 and bake 2 layer cakes according to directions. Recipe said 9 inch, I only had 8 inch pans and it was fine.
