Kitty Litter Cake:
Packet of Vanilla Pudding
Two Cakes (chocolate and vanilla, or two marble cakes)
One packet of cookies with cream inside (oreo, white oreo, off-brand)
Miniature chocolate bars or tootsie rolls
What you do:
Make pudding according to directions.
Make cake according to directions.
Grind up cookies (not too fine, but not huge pieces either. Don't make paste, I'm saying)
Place all three in litterbox and start mashing that all together. Add chocolate bars/tootsie rolls.
OPTIONAL: drops of green food colouring.
Serves small children best.
Currently working on a modified version for 'dirt cake' (uses gummi worms instead of chocolate bars, for starters) which is not a new idea but I want one I really like for myself. May involve flowerpots.
