Scoop some ice cream onto the bottom of a chocolate chip cookie. Top with another cookie and squish down to stick. {If some ice cream oozes out, take a butter knife and remove so the ice cream is even all the way around the cookie.} Roll the ice cream edges in chocolate sprinkles and place into the freezer for 30 minutes to solidify again. Repeat this process until you have 12 spider bodies.
While spiders are freezing, break pretzels apart to get legs. You’ll need 8 legs for each spider. Microwave chocolate chips for about 30 seconds or until completely melted.
To assemble spiders, remove from freezer. Dip a pretzel leg in chocolate and press into place. Repeat until all legs are attached. Take two mini M&M’s or other candies, dip in chocolate and press in place for the eyes. Freeze another 5 minutes and serve.
