Peanut Butter Spider Cookies

These peanut butter spider cookies are chewy and soft peanut butter cookies topped with a cute peanut butter cup spider! Perfect for a fun and adorable Halloween treat! 
Servings: 24


  • 1/2 cup butter (1 stick, softened)
  • 1/2 cup creamy peanut butter
  • 1/2 cup white sugar
  • 1/2 cup brown sugar
  • 1 large egg
  • 1/2 tsp vanilla extract
  • 1 1/4 cups flour
  • 3/4 tsp baking soda
  • 1/2 tsp baking powder
  • 1/4 tsp salt
  • 24-30 miniature Reese's Cups
  • 48-60 candy eyes
  • 1 cup milk chocolate chips


  • Preheat the oven to 350 degrees
  • Beat the butter and peanut butter together until it is well combined. 
  • Add in the sugars and cream for about 2 minutes or until the mixture has lightened.
  • Stir in the egg and vanilla extract.   
  • Add in the dry ingredients (flour, baking soda, baking powder, and salt) and stir into the mixture until well combined. 
  • Roll the cookie dough into 1.5 inch sized balls (you'll want about 24-30 balls total). Most recently I got 28.
  • Place cookie dough onto a cookie sheet lines with parchment paper or a silicone liner.
  • Bake for 7-8 minutes until the cookies just start to crack. They'll finish baking as they cool on the pan. 
  • Let cookies cool for about 5 minutes on the pan before transferring to a cooling rack. 
  • Allow cookies to cool on cooling rack for about 5 minutes. 
  • Unwrap Reese's peanut butter cups and place one on the top of each cookie. 
  • Allow Reese's and cookies to cool completely. 
  • Add chocolate chips to a microwave safe bowl and microwave in 30 second increments stirring after each until completely smooth. 
  • Transfer the melted chocolate into a plastic bag and cut off the corner/tip of the bag. (I just use a small ziplock bag) 
  • Pipe chocolate legs onto the cookie starting from the Reese's body out to the edge of the cookie. 
  • Add a little chocolate to the back of the candy eyes and press them onto the Reese's cup. 
  • Allow chocolate to set completely before serving.
