It’s no secret that I love Halloween. It’s my favorite holiday and as soon as September rolls around, I start searching for new Halloween food ideas for my upcoming party.

My goal is always quick, easy, and festive. These peanut butter spider cookies check all of those boxes.

These spider cookies are essentially peanut butter blossoms made with a Reese’s cup in the center instead of the traditional Hershey’s kiss. Then I add some spider legs with melted chocolate and candy eyeballs to pull it all together.

The end result is so ridiculously cute that I know I’ll need to make these more than once this year!

Just 12 ingredients are needed to make these easy spider cookies, many of which are pantry staples. Scroll down to the recipe box for full measurements.

  • Unsalted butter – At room temperature but not too soft.

  • Creamy peanut butter – Skip natural peanut butter for this recipe.
  • Egg
  • Vanilla extract – Adds part of the classic cookie flavor.
  • All-purpose flour
  • Baking soda & baking powder – Both help these cookies rise during baking.
  • Salt
  • Granulated sugar – For rolling the cookies.
  • Mini Reese’s peanut butter cups – Added to the center of each cookie.
  • Semi-sweet chocolate chips – These are melted down to create the chocolate legs.

How to Make Peanut Butter Spider Cookies

These may be the easiest Halloween cookies to make. There’s no need to chill the dough and the bake time is just around 10 minutes.

Chill the Reese’s. Unwrap 24 of the mini Reese’s cups and place in a bowl in the freezer. Preheat the oven to 350F.

Beat the butter and sugar. Beat the butter, brown sugar, and sugar with an electric mixer until smooth and fluffy.

Add the other wet ingredients. Add the peanut butter, egg, and vanilla, then beat again.

Mix in the dry ingredients. Mix in the flour, baking soda, baking powder, and salt until just combined.

Bake. Form tablespoon-sized balls from the dough, rolling it in your hands to make a uniform ball. Roll in granulated sugar then place on the baking sheet. Bake for 8 to 11 minutes.

Cool. Press a mini Reese’s into the center of each cool. Cool for at least 15 to 20 minutes on the baking sheet before moving to cool completely on a cooling rack.

Add the legs. Melt the chocolate chips in the microwave, stirring every minute. Transfer to a squeeze bottle and draw 4 legs on each side of the cookies.

Add the eyes. Use a small amount of melted chocolate to attach the candy eyes to the Reese’s cup. Allow to set completely before moving or enjoying.

Tips for Success

While these peanut butter cookies are pretty straightforward to make, I do have a few tips to make them even better.

  • Make sure the dough balls are all equal in size. You can try to eyeball it, use a cookie scoop, or weigh the dough just to be sure but making all of the cookies equal in size helps to ensure they all bake evenly.
  • Chill the peanut butter cups. I always unwrap the Reese’s cups ahead of time because it makes it easier to add them to the cookies but also because it gives me an opportunity to freeze them. I found that freezing the Reese’s helps them hold their shape more when added to the hot cookie.
  • How do I know when these are done? Your peanut butter cookies should look set and the edges should start to crack a bit. I do like to err for slightly underdone, as the cookies will continue to bake on the cookie sheet.
  • Let them cool on the baking sheet. I like to let the cookies cool on the baking sheet for at least 15 or 20 minutes. If you move them before they set, the Reese’s cup can sink and the cookie may lose its shape.
  • Add the eyes while the chocolate is warm. Using a dab of chocolate is an easy way to attach the eyeballs to the Reese’s but be sure to do it before the chocolate cools and hardens.

How to Store

Spider cookies can be stored in an airtight container for up to 3 days. They’ll be just fine at room temperature, though you may want to put parchment paper between layers if you need to stack them in case the chocolate melts.

Can I Freeze These Cookies?

Yes, you can freeze these peanut butter spider cookies – both before and after baking.

To freeze the dough, shape the balls as instructed but don’t dip them in sugar. Flash freeze on a baking sheet, then transfer to a ziploc bag or freezer container.

To freeze the baked cookies, allow them to cool completely then transfer to an airtight container. Freeze for up to 3 months.

Soft and chewy peanut butter cookies topped with Reese's, melted chocolate, and candy eyes, these peanut butter spider cookies are both easy and fun to make. The perfect Halloween dessert for your next party!

Ingredients

  • 1 stick unsalted butter, 1/2 cup, room temperature
  • ½ cup brown sugar
  • cup granulated sugar
  • ¾ cup creamy peanut butter, not natural
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 ½ cups all purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • Granulated sugar, for rolling the cookies
  • Mini Reese’s Peanut Butter Cups
  • ½ cup semi-sweet chocolate chips, for melting
  • Candy eye balls

Instructions
 

  • Unwrap about 24 mini reese’s cups, place in a bowl and put in the freezer. This helps them to maintain their shape once added to the hot cookies. Preheat the oven to 350ºF.
  • In a mixing bowl, combine the butter, brown sugar, and sugar. Beat with an electric mixer for 1 minute, until smooth and fluffy.
  • Add in the peanut butter, egg, and vanilla extract, beat again, less than 1 minute.
  • Add in the flour, baking soda, baking powder and salt, mixing on low or with a spatula just until combined. Be careful not to over mix.
  • Use a small cookie scoop or tablespoon to form tablespoon sized balls from the dough. Roll the dough between your hands to form a uniform ball, then roll in granulated sugar. Place the cookies 2-3 inches apart on a silicone lined baking sheet and bake for 8-11 minutes or until the edges of the cookies begin to crack and turn golden in color.
  • Remove the cookies from the oven and press a mini reese’s cup into the center of each cookie. Allow the cookies to cool for 15-20 minutes before moving to cooling rack. Moving the cookies while they are still warm can cause the reese’s cup to sink, losing its shape.
  • Place the chocolate chips in a microwave safe bowl. Microwave for 3 minutes on 50% power, stirring after each minute. Continue to microwave until fully melted. Transfer the melted chocolate into a squeeze bottle or a sandwich bag with the corner cut off. Draw 4 legs on each side of the cookies.
  • Use a small amount of melted chocolate on the back of the candy eye balls to attach them to the reese’s cup. Allow the chocolate to set before moving the cookies to a serving platter.
