Ingredients You’ll Need for Peanut Butter Spider Cookies

Before diving into the preparation, gather all the following ingredients to make your baking process seamless:

  • ½ cup (113g) unsalted butter, at room temperature
  • ½ cup (107g) brown sugar
  • ⅓ cup (66g) granulated sugar
  • ¾ cup (201g) creamy peanut butter (do not use natural peanut butter)
  • 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

Start by unwrapping your mini Reese’s peanut butter cups. Place them in a bowl and freeze them while you prepare the dough. Freezing helps them maintain their shape when pressed into the warm cookies. Preheat your oven to 350°F (175°C) to ensure it’s ready when your cookie dough is.

In a mixing bowl, combine the butter, brown sugar, and granulated sugar. Beat this mixture with an electric mixer for about 1 minute until it becomes smooth and fluffy. Next, add in the peanut butter, egg, and vanilla extract. Beat everything together briefly, just enough to combine the ingredients thoroughly.

Add the flour, baking soda, baking powder, and salt to the mixture. Stir these dry ingredients in on low speed or with a spatula, being cautious not to over-mix. Overworking the dough can make the cookies tough instead of soft and chewy.

Once the dough is ready, use a cookie scoop or tablespoon to form even dough balls. Roll each one between your palms until smooth, then roll them in granulated sugar. This sugary coating gives them a sweet exterior and a subtle crunch. Place the cookie balls on a silicone-lined or parchment-lined baking sheet about 2-3 inches apart.

Bake the cookies for 8-11 minutes or until the edges start to crack and turn a light golden brown. The centers should still be slightly soft.

Decorating Peanut Butter Spider Cookies with Chocolate Legs

Once the cookies come out of the oven, act quickly. Press a frozen mini Reese’s cup into the center of each warm cookie. Let the cookies cool on the baking tray for 15-20 minutes before transferring them to a cooling rack. If moved too early, the Reese’s cup can sink or become misshapen.

To make the chocolate spider legs, melt the semi-sweet chocolate chips in a microwave-safe bowl. Heat them for about 3 minutes on 50% power, stirring every minute. When the chocolate is smooth, transfer it into a piping bag, squeeze bottle, or a sandwich bag with a small corner cut off. Pipe four legs on each side of the Reese’s cup to mimic spider legs.

Adding Candy Eyes for a Finishing Touch

Dip the backs of your candy eyes into the melted chocolate and gently press them onto the Reese’s cups. This small detail turns your cookies into the cutest (and creepiest) spiders around. Allow the chocolate to set completely before arranging your cookies on a serving platter.

Helpful Tips for the Best Peanut Butter Spider Cookies

  • Always freeze the mini Reese’s cups before baking.
  • Use a cookie scoop to ensure uniform size.
  • Don’t overbake – they’ll continue to firm up after baking.
  • Let cool slightly before decorating.
  • Refrigerate dough briefly if too sticky.

Serving Ideas and Presentation for Halloween Gatherings

Serve these spider cookies on a dark platter with some fake webbing and plastic spiders scattered around for a dramatic effect. You could also include them in a spooky cookie tray with Red, White and Blue Flag Cake and Fireworks Cookies and Cream Cookies, making it a fun, festive dessert table.

Storage and Make-Ahead Instructions

Once decorated, store the cookies in a single layer inside an airtight container. They’ll last up to 4 days at room temperature. If you need to make them ahead, you can bake the cookies a day early and decorate on the day of your event. They also freeze well—just layer parchment between them and freeze in a sealed container.

Variations to Try with Spider Cookies

  • Use dark chocolate Reese’s for a more dramatic color contrast
  • Add orange gel food coloring to the dough for extra Halloween flair
  • Swap out candy eyes for mini M&Ms
  • Try a base of Cheddar Cheese Buns to give a savory-sweet twist

Avoid These Common Mistakes When Baking Spider Cookies

  • Don’t use natural peanut butter—it’s too oily.
  • Don’t skip freezing the Reese’s cups.
  • Don’t overmix the dough.
  • Don’t move the cookies too early after baking.

FAQs About Peanut Butter Spider Cookies

Can I freeze the dough?
Yes, freeze rolled dough balls and bake straight from frozen. Just add 1–2 minutes to the baking time.

What if I don’t have a piping bag?
Use a small zip bag with the corner snipped off to draw spider legs.

Can I make these gluten-free?
Yes, substitute all-purpose flour with a gluten-free blend.

Do I have to use candy eyes?
Not at all! Mini chocolate chips work just as well.
