Get ready to creep it real in the kitchen with these utterly adorable and incredibly delicious Peanut Butter Spider Cookies! Perfect for Halloween parties, bake sales, or just satisfying your sweet cravings, these cookies are a delightful twist on a classic peanut butter cookie. They’re surprisingly easy to make, and the “spider” element adds such a fun, festive touch that kids and adults alike will adore. We’ll start with a perfectly chewy peanut butter cookie base, then transform them into spooky arachnids using a few simple tricks.
Ingredients:
- ½ cup (113g) unsalted butter (1 stick, room temperature)
- ½ cup (107g) brown sugar
- ⅓ cup (66g) granulated sugar
- ¾ cup (201g) creamy peanut butter (not natural, the kind that’s well-stirred and smooth works best for texture)
- 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 the cookies, about ¼ cup)
- Mini Reese’s Peanut Butter Cups (one for each cookie, plus a few extra in case of snacking!)
- ½ cup (85g) semi-sweet chocolate chips (for melting)
- ½ tsp neutral oil (like vegetable or canola, for melting chocolate)
- Candy eye balls (a pack should be plenty)
Crafting Your Peanut Butter Spider Cookies
Now, let’s get down to the delicious business of creating these little wonders.
1. Creaming the Foundation: In a large mixing bowl, I like to start by creaming together the softened unsalted butter, brown sugar, and granulated sugar. Use an electric mixer on medium speed until the mixture is light and fluffy, and pale in color. This process incorporates air into the dough, which is crucial for achieving a tender cookie texture. This usually takes about 2-3 minutes. Don’t rush this step; a well-creamed butter and sugar mixture is the bedrock of a great cookie.
2. Adding the Peanut Butter and Wet Ingredients: Next, I beat in the creamy peanut butter until it’s well combined with the butter and sugar mixture. Then, I add the large egg and the vanilla extract. Mix on low speed until everything is just incorporated. It’s important not to overmix at this stage; we want to avoid developing the gluten in the flour too much, which can lead to tough cookies. The dough might look a little curdled at this point, and that’s perfectly normal.
3. The Dry Ingredients and Forming the Dough: In a separate medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients in your main mixing bowl, mixing on low speed until just combined. Be careful not to overmix! Once the flour is mostly incorporated, the dough should start to pull away from the sides of the bowl and form a cohesive ball. If the dough seems a bit too sticky, you can add another tablespoon of flour, but typically, this amount is just right.
4. Chilling and Shaping: This is a crucial step for preventing your cookies from spreading too much during baking. Cover the bowl with plastic wrap and refrigerate the dough for at least 30 minutes, or up to 2 days. Once chilled, place the ¼ cup of granulated sugar onto a shallow plate. Roll the chilled dough into 1-inch balls, then roll each ball in the granulated sugar. Place the sugared balls about 2 inches apart on a baking sheet lined with parchment paper. This sugar coating not only adds a lovely sparkle but also contributes to a slightly crisp exterior.
5. Baking the Perfect Base: Preheat your oven to 350°F (175°C). Bake the cookies for 10-12 minutes, or until the edges are lightly golden brown and the centers are still slightly soft. They will continue to set up as they cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. While the cookies are still warm, but not piping hot, gently press one Mini Reese’s Peanut Butter Cup into the center of each cookie. This allows the chocolate to soften slightly and adhere to the cookie, creating the spider’s body.
6. Creating the Spider Legs and Eyes: This is where the real magic happens! Once the cookies are completely cool and the peanut butter cups are firmly in place, it’s time to make the legs. Take a sharp knife and make four shallow cuts from the edge of the peanut butter cup towards the edge of the cookie on each side, creating eight “legs.” Don’t cut too deep, just enough to score the cookie. For the eyes, gently press two candy eyeballs into the top of the Mini Reese’s Peanut Butter Cup. If your candy eyeballs aren’t sticking, you can melt a tiny bit of the chocolate chips with the neutral oil (microwave in 15-second intervals, stirring in between, until smooth) and use a toothpick to dab a small amount onto the back of the candy eye before pressing it onto the peanut butter cup. These adorable little spiders are now ready to impress! Enjoy every spooky, peanut buttery bite!

Frequently Asked Questions:
Can I make these cookies ahead of time?
Absolutely! These cookies store very well. Once completely cooled, you can store them in an airtight container at room temperature for up to 3-4 days. This makes them perfect for making a day or two in advance for parties or events.
What can I use if I don’t have black licorice for the spider legs?
No problem at all! You have a few great alternatives. You can use thin black string licorice, black candy melts piped into leg shapes, or even black frosting. Some people have even used pretzel sticks dipped in black candy melts. Just ensure whatever you use is sturdy enough to stand up as legs.
Are these cookies nut-free?
Unfortunately, no. As the name suggests, these are Peanut Butter Spider Cookies, so they contain peanut butter and are not suitable for individuals with peanut allergies. If you need a nut-free option, I recommend searching for a different cookie recipe that specifically caters to allergy restrictions.
