Step‑by‑Step Instructions for Peanut Butter Spider Halloween Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) and lining two baking sheets with parchment paper. This ensures your Peanut Butter Spider Halloween Cookies will bake evenly and won’t stick. While the oven warms up, take a moment to gather your ingredients to make the process smooth and enjoyable.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, and a pinch of salt. Whisking thoroughly combines these dry ingredients, ensuring the baking soda is evenly distributed for that perfect puff in your cookies. Set this bowl aside, as we will bring the wet and dry ingredients together shortly.
Step 3: Cream Butter and Sugars
In a large mixing bowl, use an electric mixer to beat together ½ cup of room-temperature unsalted butter, ½ cup of light brown sugar, and ½ cup of granulated sugar until fluffy and light—about 2 to 3 minutes. This step creates the cookie’s tender base. You’ll know it’s ready when the mixture appears creamy and pale.
Step 4: Add the Wet Ingredients
Next, mix in 1 cup of smooth peanut butter, 1 large egg, 1 teaspoon of vanilla extract, and ¼ cup of whole milk. Beat on low until everything is thoroughly combined and smooth. The mixture should look cohesive and slightly glossy, forming the rich foundation of your Peanut Butter Spider Halloween Cookies.
Step 5: Combine Mixtures
Gradually add your dry mixture to the wet ingredients, mixing gently on low until just combined. Avoid overmixing; you want the dough to remain thick and slightly sticky. Use a spatula to scrape down the sides of the bowl to ensure everything is integrated, forming a delicious dough that is ready for chilling.
Step 6: Chill the Dough
Cover the cookie dough with plastic wrap and refrigerate for at least 30 minutes. Chilling is crucial for maintaining the shape of your cookies while baking, preventing them from spreading too much. This time helps the flavors meld, resulting in more extraordinary peanut butter cookies.
Step 7: Shape Cookies
Once chilled, scoop out tablespoon-sized portions of dough. Roll each portion into a ball and place them on your prepared baking sheets about 2 inches apart. Gently flatten each ball with your palm to create a thicker base, ensuring that your Peanut Butter Spider Halloween Cookies have a lovely shape.
Step 8: Bake
Bake the cookies in your preheated oven for 10-12 minutes, or until the edges are golden brown and the centers are set but still soft. Keep an eye on them, as every oven is different! They should look slightly puffy and irresistible once done. Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack.
Step 9: Assemble Spiders
While the cookies are still warm, gently press a miniature Reese’s Peanut Butter Cup into the center of each cookie to create the “spider body.” Then, melt your semi-sweet chocolate and pipe four legs on each side using a piping bag or a zip-top bag with the corner snipped off. Add candy eyes for that delightful finishing touch!
Step 10: Firm Up
Refrigerate the cookies for about 15-20 minutes to allow the chocolate decoration to set firmly. This final chill will enhance not only the cookie’s appearance but also ensure that the chocolate and candy eyes securely adhere to the cookies. Your Peanut Butter Spider Halloween Cookies are now ready to surprise and delight!

Make Ahead Options
These Peanut Butter Spider Halloween Cookies are perfect for meal prep enthusiasts! You can prepare the cookie dough up to 24 hours in advance by mixing all the ingredients and refrigerating the dough. This chilling not only enhances the flavor but also keeps the cookies from spreading too much during baking. Alternatively, you can freeze the shaped cookie dough balls for up to 1 month; when ready to bake, simply thaw them overnight in the refrigerator before popping them in the oven. For decorating, you can assemble the spiders right after baking, ensuring a delightful treat that’s just as delicious as if made fresh. With these make-ahead tips, your Halloween festivities will be a breeze!

Peanut Butter Spider Halloween Cookies Recipe FAQs
How do I select the best peanut butter for my cookies?
Absolutely! For these Peanut Butter Spider Halloween Cookies, I recommend using smooth, creamy peanut butter like Skippy or Jif. This ensures a soft texture and allows the cookies to hold their shape better. Avoid crunchy peanut butter, as it can make the dough crumbly and affect the final result.
What’s the best way to store these cookies?
Very! Store your cookies in an airtight container at room temperature for up to 1 week to keep them fresh and chewy. If you’re looking to extend their shelf life, consider refrigerating them; they can stay fresh in the fridge for up to 10 days. Just make sure they’re well-covered to avoid drying out.
Can I freeze the cookie dough for later use?
Certainly! To freeze your dough for these Peanut Butter Spider Halloween Cookies, scoop out tablespoon-sized portions and roll them into balls. Place them on a baking sheet to freeze solid for about an hour, then transfer the frozen balls into a resealable plastic bag. They can be stored in the freezer for up to 1 month. When you’re ready to bake, simply thaw in the refrigerator overnight and bake as directed.
What should I do if my cookies spread too much during baking?
No worries! If your cookies spread excessively, it likely means the dough wasn’t chilled enough before baking. Next time, refrigerate the dough for at least 30 minutes before scooping and baking. If they still spread, try checking your oven temperature with an oven thermometer to ensure it’s accurate, or consider adding a little more flour next time.
Are these cookies suitable for kids with peanut allergies?
It’s crucial to keep allergies in mind! If you’re making these cookies for kids with peanut allergies, I recommend using a nut-free alternative, like sunflower seed butter or soy nut butter. Just make sure to adjust any toppings, as many candies may also contain peanuts.
How long can I keep these cookies after Halloween?
These enchanting cookies can be stored for up to 1 week at room temperature. You can also keep the festive spirit alive by freezing the extras for up to 1 month. Simply thaw them at room temperature for a delightful treat even after Halloween has passed!
