These Peanut Butter Spider Cookies are soft, chewy, and full of spooky Halloween charm. Made with a classic peanut butter cookie base, mini Reese’s cups, and chocolate spider legs, they’re the perfect fun and festive treat for your next Halloween party.

Ingredients

  • ½ cup unsalted butter, room temperature
  • ½ cup brown sugar
  • ⅓ cup granulated sugar
  • ¾ cup creamy peanut butter (not natural)
  • 1 large egg
  • 1 tsp vanilla extract
  • 1½ cups all-purpose flour
  • 1 tsp baking soda
  • ½ tsp baking powder
  • ½ tsp salt
  • Extra granulated sugar (for rolling)
  • 24 mini Reese’s Peanut Butter Cups (frozen)
  • ½ cup semi-sweet chocolate chips (for melting)
  • Candy eyeballs (for decorating)

Instructions

  1. Place unwrapped Reese’s in the freezer to chill while preparing the dough.
  2. Preheat oven to 350°F (175°C) and line a baking sheet with a silicone mat or parchment.
  3. In a bowl, cream together butter, brown sugar, and granulated sugar until fluffy.
  4. Add peanut butter, egg, and vanilla. Mix until smooth.
  5. Stir in flour, baking soda, baking powder, and salt until just combined.
  6. Scoop dough into 1-inch balls, roll in sugar, and place 2–3 inches apart on baking sheet.
  7. Bake 8–11 minutes or until lightly golden and cracked.
  8. Immediately press a frozen Reese’s cup into each cookie center. Let cool 15–20 minutes.
  9. Melt chocolate chips in the microwave at 50% power, stirring until smooth.
  10. Use a piping bag or zip-top bag to draw spider legs.
  11. Attach candy eyes to the Reese’s using a dab of melted chocolate. Let set completely before serving.

Notes

  • Freeze Reese’s before baking to help them hold their shape.
  • Natural peanut butter is not recommended—it can make cookies spread too much.
  • Use Halloween-themed eyes, sprinkles, or other candies to customize.
  • Store cookies at room temperature or freeze for longer storage.
