In a medium-sized bowl, cream the butter and sugar until light and fluffy.
Mix in the egg.
Mix in the vanilla, salt, and flour until well-combined.
Cover and chill the dough for about four hours.
Preheat oven to 350 F.
Roll out cookie dough to about 1/4" thick and cut into spider webs.
Use the circle cookie cutter or the spider cookie cutter (depending on whether you want the amber look) to cut holes in the webs where the candy will go.
While the cookies are baking, crush your candy of choice in a food processor or with a mallet.
Place cookies on a cookie sheet lined with a Silpat or parchment paper.Bake cookies with holes for six minutes.
Remove the cookies from the oven and fill the holes with the candy pieces.
Bake for two more minutes or until the candy is melted and the edges are brown.
If using gummy spiders, place gummy spiders on the “amber” as soon as the cookie is removed from the oven. They should melt a little bit into the “amber”.
Set cookies on a cooling rack or the counter to cool.Once cookies are cool, pipe webbing onto the cookies using your frosting of choice and a small round piping tip.
