Step‑by‑Step Instructions for Peanut Butter Spider Halloween Cookies
Step 1: Prep Dough
In a large mixing bowl, cream together ½ cup unsalted butter with ½ cup granulated sugar and ½ cup light brown sugar until the mixture is light and fluffy, about 4-5 minutes. Next, incorporate 1 cup of smooth peanut butter, followed by 1 egg, 1 teaspoon vanilla extract, and 2 tablespoons of whole milk, stirring until all ingredients are well combined and smooth.
Step 2: Combine Dry Ingredients
In a separate bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of salt until evenly mixed. Gradually add the dry mixture to the wet ingredients, stirring gently until just combined. This will form the dough for your Peanut Butter Spider Halloween Cookies, which should be soft but not sticky.
Step 3: Chill Dough
Cover the dough with plastic wrap and refrigerate for at least 30 minutes. Chilling the dough is crucial, as it helps prevent excessive spreading while baking, ensuring your cookies remain thick and chewy. You’ll know it’s ready when it’s firm to the touch and still slightly soft when pressed.
Step 4: Bake Cookies
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper. Once chilled, scoop tablespoon-sized portions of dough and place them about 2 inches apart on the prepared baking sheet. Bake for 10-12 minutes, until the edges are golden while the centers remain soft. Let them cool on the sheet for 3-5 minutes before transferring to a wire rack.
Step 5: Add Toppings
While the cookies cool slightly, unwrap your miniature Reese’s Peanut Butter Cups. Gently press one onto the center of each cookie, creating the body of the spider. In a microwave-safe bowl, melt about ½ cup of semi-sweet chocolate, stirring until smooth. Using a piping bag or a fork, pipe chocolate legs around each Reese’s to create a spider look. Finish with candy eyes to complete the decoration.
Step 6: Set Designs
Once decorated, place the cookies in the refrigerator for about 10 minutes to allow the chocolate to set. This ensures that your Peanut Butter Spider Halloween Cookies hold their adorable shape and remain visually appealing for your Halloween gathering. When ready, serve alongside milk or hot cocoa for a festive treat!

Expert Tips for Peanut Butter Spider Halloween Cookies
-
Chill the Dough: Allowing the dough to chill for at least 30 minutes prevents spreading, keeping your cookies soft and chewy. This step is crucial for achieving the perfect texture.
-
Use Creamy Peanut Butter: Opt for smooth peanut butter rather than crunchy varieties for the best results. Creamy peanut butter helps create a uniform dough and delightful chewiness.
-
Cool Before Topping: Let the cookies cool slightly before adding toppings. This helps maintain the cookie shape and prevents melting the Reese’s when pressed on.
-
Watch Your Chocolate Temperature: When melting chocolate for the spider legs, ensure it’s not too hot. Use it just melted; this helps prevent melting your plush Reese’s Peanut Butter Cups.
-
Get Creative with Toppings: Feel free to swap out Reese’s with other favorites like caramel-filled chocolates or use colorful melted chocolate for a festive twist. Customizing toppings can make each batch special!
Enjoy making your delightful Peanut Butter Spider Halloween Cookies!
Make Ahead Options
These Peanut Butter Spider Halloween Cookies are ideal for busy home cooks looking to save time without sacrificing flavor or fun! You can prepare the dough up to 24 hours in advance by following the initial steps and then refrigerating it in an airtight container. This prevents browning and ensures the dough maintains its quality. Additionally, you can make the chocolate spider legs ahead of time, storing them in the fridge for up to 3 days. When it’s time to bake, simply scoop and bake the chilled dough as directed. After the cookies cool slightly, add the pre-made Reese’s and chocolate decorations for an easy and delightful treat that’s just as good as fresh!

Peanut Butter Spider Halloween Cookies Recipe FAQs
What type of peanut butter should I use for the cookies?
Absolutely! I recommend using smooth, creamy peanut butter for the best texture and flavor. Crunchy peanut butter can affect the dough consistency, making your cookies less tender and chewy. Stick with creamy peanut butter to achieve that delightful, rich flavor and soft center!
How should I store the Peanut Butter Spider Halloween Cookies?
For the freshest and softest cookies, store them in an airtight container at room temperature for up to 1 week. If you prefer your cookies with a firmer texture, feel free to refrigerate them, where they can last up to 2 weeks. Just make sure they’re sealed tight to maintain their delicious flavor!
Can I freeze these cookies?
Certainly! To freeze your Peanut Butter Spider Halloween Cookies, first place them in a single layer on a baking sheet and freeze until solid. Once frozen, transfer them to a freezer-safe bag. They’re best enjoyed within 2-3 months to ensure optimal flavor and softness. If you want to enjoy them later, simply microwave them for about 10-15 seconds or let them thaw at room temperature.
What should I do if my cookies spread too much while baking?
No worries, it happens to the best of us! If your cookies spread excessively, there are a couple of things to check. First, make sure your butter is at room temperature, not too soft or melted. Next, ensure that you’ve chilled the dough for the recommended 30 minutes before baking. Finally, avoid overmixing your dough; gently combine wet and dry ingredients for the best texture!
Are these cookies safe for pets?
It’s very important to keep in mind that chocolate is toxic to dogs and other pets. So, ensure your Peanut Butter Spider Halloween Cookies are kept out of reach of your furry friends! If you’re looking for a pet-friendly option, you could try substituting the chocolate with carob or simply leave off the decorations. Always prioritize your pet’s safety!
Can I adapt the recipe for dietary restrictions?
Definitely! If you need to cater to specific dietary needs, you can substitute whole milk with almond milk or oat milk to make it non-dairy. For those avoiding gluten, try using a gluten-free all-purpose flour blend in place of regular flour. Additionally, if you have a nut allergy, consider using sun butter or another nut-free alternative in place of peanut butter to create a safe and enjoyable treat for everyone!
