(sorry- the ghosts were eaten before I had a decent picture of them. I'll try to find one from last year to post that is up close.)
You can make the Rice Krispies treats yourself, but since my focus here is the actual ghost, I'm not including those directions.
Halloween Ghost Recipe
Rice Krispies Treats
Marshmallow creme fondant
Circus Peanuts candy
Cut a Circus peanut candy in half and attach to front of a rice krispies treat at the base for the shoes. Drape marshmallow fondant over top of treat. Push two chocolate chips in front for eyes. Make a hat or other item by smashing a gum drop for the brim and attaching another to the top center. Place on Ghost. Everything is really sticky and you shouldn't need frosting to attach any items.
Planning Tip: Keeps well up to 1 week at room temperature in closed container
1 tub or jar (7 or 7 ½ oz) marshmallow cream (such as Marshmallow Fluff or Crème)
2 ¾ to 3 ¼ cups confectioners’ sugar
(Tip: Before measuring or stirring the marshmallow cream, lightly coat measuring cups and utensils with nonstick cooking spray.)
Scrape marshmallow cream into a large bowl. Stir in as much sugar as possible, kneading in remaining sugar until a smooth dough forms. (Dough should be stiff yet pliable.) Wrap airtight in plastic wrap until ready to use.
