Halloween is a holiday for pulling out all the stops, for having fun with all kinds of ghoulish decorations. Here's a scary-good way to go big and give kids and grown-ups a thrill—3-D chocolate spiders that perch on top of cupcakes and definitely give you the creepy-crawlies. Dare you reach for a sweet treat, lest these spiders crawl onto your hand? The chocolate arachnids are frighteningly easy to make, requiring readily found craft-store ingredients and just a few steps. Any leftover chocolate can turn into eerie spiderwebs.
