These spooky spider marshmallow cookies are an easy treat for Halloween. I used marshmallow Whippet Cookies (from my local market) for these little spooky spiders. You can make the spider legs by filling a pastry bag (or ziplock bag) with melted chocolate and piping the little legs onto wax paper (I used a non-stick silpat). Don't forget to pipe the legs in each direction. Refrigerate until legs are hard and use a little more melted chocolate to attach the legs. I bought the candy eyes at Michaels. They are in the baking aisle. Enjoy!
