Step‑by‑Step Instructions for Peanut Butter Spider Cookies
Step 1: Prepare Your Peanut Butter Cups
Begin by placing the mini Reese’s cups in the freezer for about 20 minutes. This chilling process ensures they retain their shape when baked and won’t melt too much. As the cups cool, gather your ingredients and preheat your oven to 350°F (175°C).
Step 2: Mix the Wet Ingredients
In a large mixing bowl, use an electric mixer to cream together ½ cup of softened unsalted butter, ½ cup of brown sugar, and ½ cup of granulated sugar until light and fluffy, about 3-4 minutes. Then, add 1 cup of creamy peanut butter, 1 large egg, and 1 teaspoon of vanilla extract, mixing until fully combined.
Step 3: Combine the Dry Ingredients
In a separate bowl, whisk together 1 ½ cups of all-purpose flour, 1 teaspoon of baking soda, 1 teaspoon of baking powder, and ½ teaspoon of salt. Gradually add this dry mixture to the wet ingredients in the mixing bowl, stirring gently until just combined. Be careful not to over-mix, as this can lead to tough cookies.
Step 4: Shape the Cookie Dough
Using a tablespoon or cookie scoop, form the dough into tablespoon-sized balls. Roll each ball in granulated sugar for a sweet crunch and place them on a baking sheet lined with parchment paper, leaving about 2 inches between each cookie for spreading while baking.
Step 5: Bake the Cookies
Once your oven is preheated, bake the cookie dough balls for 8-11 minutes, or until they are lightly golden around the edges. The centers might look slightly underbaked, which is perfect for the soft, chewy texture of your Peanut Butter Spider Cookies.
Step 6: Press in the Reese’s Cups
After removing the cookies from the oven, immediately press a chilled Reese’s cup into the center of each cookie. Let the cookies sit on the baking sheet for 15-20 minutes to cool completely; this will allow the cookies to set and the Reese’s to soften slightly.
Step 7: Add Spider Legs and Eyes
To create the spider legs, melt ½ cup of semi-sweet chocolate chips in the microwave, stirring every 30 seconds until smooth. Using a piping bag or a zip-top bag with a corner snipped off, pipe chocolate legs extending from each Reese’s cup. Secure candy eyeballs on top of the melted chocolate, giving your Peanut Butter Spider Cookies their delightful and spooky finish.

How to Store and Freeze Peanut Butter Spider Cookies
Room Temperature: Keep cookies in an airtight container at room temperature for up to 3 days for optimal freshness. Place parchment paper between layers to prevent sticking.
Fridge: If you prefer a firmer cookie, store them in the fridge for up to a week. Just remember that refrigeration can alter the texture slightly.
Freezer (Dough): For make-ahead convenience, roll cookie dough into balls and flash freeze them on a baking sheet. Once frozen, transfer to a zip-top bag, where they’ll keep for up to 3 months.
Freezer (Baked Cookies): Baked cookies can also be frozen in an airtight container for up to 3 months. Thaw at room temperature before enjoying, or heat briefly in the microwave for a warm, gooey treat!
Expert Tips for Peanut Butter Spider Cookies
Chill for Success: Ensure your mini Reese’s cups are chilled before baking to prevent them from melting into puddles. This keeps their shape intact for that perfect “spider body.”
Rolling Technique: Roll the dough balls in granulated sugar for a sweet crunchy exterior, but don’t skip this step—it’s essential for that delightful texture contrast.
Avoid Overmixing: When combining dry and wet ingredients, mix until just combined. Overmixing can lead to tough cookies instead of the soft, chewy Peanut Butter Spider Cookies you want.
Watch Your Bake Time: Keep an eye on the cookies as they bake. Take them out when they’re lightly golden—even if they seem slightly underbaked in the center; they will set as they cool.
Proper Storage: Store your cookies in an airtight container at room temperature and use parchment paper between layers to prevent sticking. Enjoy them fresh within three days for the best taste!
Make Ahead Options
These Peanut Butter Spider Cookies are perfect for busy home cooks looking to save time during the Halloween rush! You can prepare the cookie dough up to 3 days in advance and store it in an airtight container in the refrigerator. Alternatively, you can roll the dough into balls and freeze them for up to 3 months. When you’re ready to bake, simply place the frozen dough balls on a baking sheet and bake them straight from the freezer, adding a couple of extra minutes to the baking time. For the best results, press the chilled Reese’s cups into the cookies immediately after baking and follow the decorating steps to maintain that delightful presentation. Enjoy these charming treats without the last-minute stress!

Peanut Butter Spider Cookies Recipe FAQs
How do I choose the right peanut butter for the recipe?
Absolutely! It’s essential to use creamy, not natural, peanut butter for these cookies. Natural peanut butters often separate and can yield less desirable texture in your cookies. Look for a brand that lists just peanuts (and maybe salt) as the only ingredients for the best flavor and consistency.
How should I store the cookies, and how long do they last?
You can store the Peanut Butter Spider Cookies in an airtight container at room temperature for up to 3 days. If you’re looking to keep them for longer, use parchment paper between layers to prevent them from sticking together. They can also be stored in the fridge for up to a week, but be aware that this might alter their texture slightly.
Can I freeze the cookie dough before baking? What’s the best method?
Yes! For convenience, roll the dough into tablespoon-sized balls and place them on a baking sheet in the freezer for about 1-2 hours until frozen solid. Then transfer the balls into a zip-top bag. They will keep well in the freezer for up to 3 months. When ready to bake, simply preheat the oven and bake straight from frozen—just add an extra minute or two to the baking time.
What should I do if the cookies spread too much while baking?
Very! If your cookies spread too much, it’s likely due to the dough being too warm or not enough flour. Make sure you’re chilling the mini Reese’s cups before baking, as well as forming the dough into balls and chilling them for about 30 minutes before placing them on the baking sheet. You could also check your flour measurement—too little can make them spread more than desired.
Are there any allergy considerations for this recipe?
Absolutely! This recipe contains peanut butter, which is a common allergen. If you’re serving guests or family with nut allergies, consider swapping out the peanut butter with sunflower seed butter, which would also add a delightful flavor while being nut-free. Also, ensure that any candy decorations are free from allergens, as some may contain traces of peanuts or other nuts.
How can I adjust the recipe for gluten-free needs?
You can substitute the all-purpose flour with a 1:1 gluten-free flour blend! This works wonderfully without compromising the cookie’s soft and chewy texture. Just be sure to double-check other ingredients like baking powder and any candy toppings to ensure they are gluten-free as well!
