Frost's Hat cookies: Oreos with a marshmallow. Then dip in melted chocolate. Sprinkle with edible white "snow" / glitter while chocolate is still sticky. You may need to attach the oreo & marshmallow together using a tad bit of frosting so they stay together while you are dipping in chocolate. Lay on tray covered with wax paper to until hardened. Transfer to serving dish. Perhaps sprinkle with some powdered sugar for more "effect."
