Chewy Brown Sugar Peanut Butter Spider Cookies

1. Preheat the oven to 350° F. Line a baking sheet with parchment paper.
2. In a bowl, beat together the butter, brown sugar, and peanut butter until light and fluffy, 2 minutes. Beat in the maple syrup, then add the egg and vanilla. Beat until creamy. Add the flour, baking soda, and salt.
3. Scoop the dough out into rounded 1 tablespoon size balls. Place 2 inches apart on the prepared baking sheet.
4. Bake for 6-7 minutes. Remove the pan from the oven and tap the baking sheet on the counter two times to flatten the cookies down. Return to the oven and bake another 3 minutes, until the cookies are just beginning to set on the edges, but still doughy in the center. They will continue to cook slightly as they sit on the baking sheet. 
5. Top each cookie immediately with an upside-down peanut butter cup. Then 1 milk dud (see photos for guidance). Let cool. Spoon the melted chocolate into a sandwich bag and snip the corner off. Draw 3 legs on either side of the Reese's cup. Dot the eyes with chocolate, then attach 2 eyes on top of each Milk Dud. Let set until the chocolate is firm.
6. Alternately, you can cover the pretzel pieces in chocolate and attach those as legs.
