What you need:
New cat box and scooper
German chocolate cake mix
German chocolate icing
Vanilla sandwich cookies
Green or blue food coloring
Prepare cake as directed. Let cool. In the meantime, crush up the vanilla cookies. Set aside about 1/4 of the crushed cookies in separate plastic bag. Add food coloring. The desire is to get the clumping litter color effect.
Once cake is cooled add to the clean cat box. (always use a new box and scooper and wash it- I know this is obvious but just making sure everyone knows)
Ice cake with the German chocolate icing. Add the uncolored cookie crumbs. Add clumps of the colored cookie crumbs. Add globs of chocolate icing. Then add tootsie rolls. It's funny to twist and shape the tootsie rolls and make icing globs on the side of the box. Makes it look very realistic.
This cake is always a hit and I've even had kids who wouldn't touch it cause it looked so gross.
