Ingredients
  

  • ½ cup 113g unsalted butter, room temperature
  • ½ cup 107g brown sugar
  • cup 66g granulated sugar
  • ¾ cup 201g creamy peanut butter (not natural)
  • 1 large egg
  • 1 tsp vanilla extract
  • 1 ½ cups 180g all-purpose flour
  • 1 tsp baking soda
  • ½ tsp baking powder
  • ½ tsp salt
  • Granulated sugar for rolling
  • 24 mini Reese’s Peanut Butter Cups unwrapped and frozen
  • ½ cup 85g semi-sweet chocolate chips, for melting
  • Candy eyeballs for decorating

Instructions
 

Prepare Reese’s Cups

  • I unwrap 24 mini Reese’s cups and freeze them in a bowl to hold shape for this creepy peanut butter cookies.

Preheat Oven

  • I preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper for this spooky Halloween treat.

Mix Cookie Dough

  • I beat ½ cup butter, ½ cup brown sugar, and ⅓ cup granulated sugar with a mixer for 1 minute until fluffy. I add ¾ cup peanut butter, 1 egg, and 1 tsp vanilla, mixing briefly. I stir in 1 ½ cups flour, 1 tsp baking soda, ½ tsp baking powder, and ½ tsp salt on low speed for this simple recipe.

Shape Cookies

  • I scoop dough into balls, roll in granulated sugar, and place 2–3 inches apart on the baking sheet for this festive dessert.

Bake Cookies

  • I bake for 8–11 minutes until edges crack and turn golden, keeping centers soft for this creepy peanut butter cookies.

Add Reese’s Cups

  • I press a frozen Reese’s cup into each warm cookie right after baking, then cool on the tray for 15–20 minutes for this spooky Halloween treat.

Decorate with Chocolate Legs

  • I melt ½ cup chocolate chips in a microwave-safe bowl at 50% power for 3 minutes, stirring every minute. I pipe 4 legs on each side of the Reese’s cup using a piping bag for this Peanut Butter Spider Cookies.

Add Candy Eyes

  • I dip candy eyes in melted chocolate and press onto Reese’s cups, letting chocolate set for this festive dessert.

Notes

  • Freeze Reese’s cups before baking to help them keep their shape.
  • Refrigerate dough briefly if it feels sticky when rolling.
  • Use a piping bag or zip-top bag to easily pipe the spider legs.
  • Store cookies in an airtight container for up to 4 days or freeze in layers.
  • Decorating tip: Let cookies cool before adding chocolate legs and eyes to avoid smudging.
