Marshmallow Peeps (halloween shapes!)
Icing for writing on the gravestones (optional)
First, make the cake mix and frost the cake. Then, insert the Milano cookies halfway into the cake.
If you'd like, before doing this, use a toothpick to write some funny sayings on them. Some good ones are "Rusty Gates" and "B.A. Ghoul" You can find a ton more here: http://www.costumediscounters.com/csc_inc/html/static/articles/epitaphs-funnynames.html
Eat the frosting out of the oreos and then put them into a plastic bag and crush them up. Sprinkle them around the gravestones to look like dirt that was recently dug up. Throw some gummy worms around and cover them with dirt.
Stick some marshmallow peeps around the gravestones and you have a yummy graveyard cake!
