How to Make Spooky Spider Cookies
Mix Dough: In a stand mixer, combine softened butter and both sugars until creamy. Add peanut butter, followed by eggs and vanilla, mixing until smooth and well blended.
Combine Dry Ingredients: In a separate bowl, whisk together flour, cornstarch, baking soda, and salt. Gradually mix this dry blend into the wet ingredients until just combined.
Chill Dough: Cover the dough with plastic wrap and refrigerate for 30 minutes to 1 hour. This prevents stickiness and helps shape the cookies easily.
Bake Cookies: Preheat your oven to 375 °F (190 °C). Roll the chilled dough into balls, coat them in granulated sugar, then space them out on a lined baking sheet. Bake for 8-10 minutes, and as you remove them, press a chilled Reese s in the center. Let cool completely.
Create Cobwebs: Microwave mini marshmallows in small bowls until puffed. Use your fingers to stretch and drape the marshmallows over the cooled cookies to create spiderwebs.
Pipe Decor: Melt dark chocolate and transfer to a piping bag. Fill the indents of the cookies with chocolate, place a Reese s on top, and pipe legs for the spiders. Add candy eyes for the finishing touch!

What if my cookie dough seems too sticky?

To make stretching and draping mini marshmallows easier, heat them in small bowls in the microwave for about 10-15 seconds.
