Cookies with faces on them or cupcakes with eyes. 
Just wondering if you had the party yet and what you ended up doing. If you have pictures of the food.... I'd love to see what you decided on.
oooh yes, do post pics if you can. We could use some yummy action shots around here!
For a cake make a barbie princess cake. All you do is buy your cake mix. Mix it like you normally would. Bake it ina glass bowl, to make the dress. Then use a barbie and stick her in the bowl portion. Then frost up on her and on the dress part. You can also bake a round cake and put the dress on top of it.
