How to Make Peanut Butter Spider Halloween Cookies
-
Prepare Dough: In a large mixing bowl, cream together unsalted butter, light brown sugar, and granulated sugar until the mixture is light and fluffy. Incorporate the smooth peanut butter, then mix in the egg, vanilla extract, and whole milk until everything is well combined.
-
Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this mixture to the wet ingredients, blending until the dough is smooth and no flour streaks remain.
-
Chill Dough: Cover the dough and refrigerate it for at least one hour. This chilling step helps the cookies maintain their shape while baking and enhances the flavors.
-
Form Cookies: Preheat your oven to 350°F (175°C). Scoop out chilled dough, roll it into balls, and space them out on a parchment-lined baking sheet, leaving room for spreading.
-
Bake: Place the cookies in the oven and bake for 10-12 minutes. They should be set at the edges with soft centers; don’t overbake!
-
Decorate: Allow cookies to cool for 3-5 minutes. Gently press a Reese’s Peanut Butter Cup into the center of each cookie. Once cooled completely, melt semi-sweet chocolate and pipe spider legs onto each cookie, finishing with candy eyes for that extra spooky touch.
Optional: Add colorful sprinkles for an extra festive flair!

Helpful Tricks for Peanut Butter Spider Halloween Cookies
-
Chill the Dough: Refrigerating the dough for at least one hour prevents your cookies from spreading too much, ensuring they maintain a lovely shape instead of turning flat.
-
Proper Peanut Butter: For the best texture, opt for creamy peanut butter rather than crunchy. Using natural peanut butter can lead to dryness, making your cookies less enjoyable.
-
Timing is Key: Wait for the cookies to cool slightly before adding the Reese’s Peanut Butter Cups. If they’re too hot, the candy will melt and lose its shape, ruining that delightful spider look!
-
Decorative Options: Feel free to get creative with candy toppings! Substitute Reese’s with alternatives like Snickers or Twix for a fun twist to your Peanut Butter Spider Halloween Cookies.
-
Watch the Baking Time: Keep an eye on your oven; pulling the cookies out when the edges are set but the centers are still soft is crucial to achieving that perfect chewy texture!
Storage Tips for Peanut Butter Spider Halloween Cookies
- Room Temperature: Store cookies in an airtight container at room temperature for up to 1 week to keep them chewy and delicious.
- Fridge: If you prefer even softer cookies, refrigerate them in an airtight container for up to 2 weeks. This keeps them fresh while enhancing flavors.
- Freezer: These Peanut Butter Spider Halloween Cookies can be frozen for up to 3 months. Place in a freezer-safe container with parchment paper between layers to prevent sticking.
- Reheating: To enjoy a warm cookie, reheat in the microwave for 10-15 seconds or let them sit at room temperature for a little while.
Make Ahead Options
These Peanut Butter Spider Halloween Cookies are perfect for busy home cooks looking to save time! You can prepare the cookie dough up to 24 hours in advance; simply follow the initial steps and then refrigerate the dough covered until you’re ready to bake. This chilling not only enhances the flavors but also prevents the cookies from spreading too much during baking. When you’re ready to serve, scoop and bake straight from the fridge, adding a few extra minutes to your baking time if needed. Remember, for the best results, wait until the cookies have cooled slightly before pressing the Reese’s cups on top and piping the chocolate spider legs. Enjoy a fun baking experience with minimal stress by prepping ahead!

Peanut Butter Spider Halloween Cookies Recipe FAQs
What kind of peanut butter should I use for the cookies?
I highly recommend using creamy peanut butter for these cookies. It gives the ideal texture, allowing the cookies to be chewy and soft. Avoid natural peanut butter, as it can lead to dryness, making your cookies less enjoyable.
How should I store my Peanut Butter Spider Halloween Cookies?
Store your cookies in an airtight container at room temperature for up to 1 week. For softer cookies, consider refrigerating them in a sealed container, which will keep them fresh for up to 2 weeks. If you want to extend their shelf life, freeze them in a freezer-safe container for up to 3 months with layers of parchment paper in between to prevent sticking.
Can I freeze the cookie dough before baking?
Absolutely! If you want to get ahead of the game, you can prepare the cookie dough and roll it into balls. Place them on a baking sheet lined with parchment paper and freeze them for 1-2 hours. Once frozen, transfer the balls to a freezer-safe bag or container. They can be kept for up to 3 months. Just bake them directly from the freezer, extending the baking time by a couple of minutes.
What should I do if my cookies spread too much while baking?
If your cookies spread too much, it’s likely because the dough wasn’t chilled enough before baking. Make sure to refrigerate the dough for at least one hour before rolling them into balls and baking. Additionally, ensure that your oven temperature is accurate because an oven that is too hot can cause excessive spreading.
Can I use different toppings for my cookies?
Very! Feel free to get creative with your toppings. While Reese’s Peanut Butter Cups are the star of this recipe, you can easily substitute them with other chocolates like Twix or Snickers for a delightful twist. You can also use colorful sprinkles to match various festive themes beyond Halloween.
Are these cookies suitable for kids or those with allergies?
These cookies primarily contain peanuts, dairy, and gluten, so they might not be suitable for those with allergies. However, if you need a nut-free version, you can experiment with sunbutter or soy nut butter, and for a gluten-free option, use a gluten-free flour blend. Always check specific ingredient packaging for allergen information.
