Step‑by‑Step Instructions for Peanut Butter Spider Cookies
Step 1: Prepare the Reese’s
Begin by unwrapping 24 mini Reese’s Peanut Butter Cups and placing them in the freezer for at least 15 minutes. This step is crucial to keep them firm when baking, ensuring they hold their shape in the cookie. While they chill, you can prepare the cookie dough, maximizing efficiency.
Step 2: Mix Wet Ingredients
In a large mixing bowl, beat together ½ cup of room temperature unsalted butter, ½ cup of brown sugar, and ½ cup of granulated sugar until the mixture is light and fluffy, about 2-3 minutes. Next, stir in 1 cup of creamy peanut butter, 1 large egg, and 1 teaspoon of vanilla extract, mixing until everything is smooth and well blended.
Step 3: Combine Dry Ingredients
In another 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, stirring just until everything is combined to avoid overmixing. Your peanut butter cookie dough should be thick and ready for shaping.
Step 4: Shape Cookies
Preheat your oven to 350°F (175°C). Roll tablespoon-sized balls of the dough in granulated sugar for a sweet crust and place them on a baking sheet lined with parchment paper, spaced about 2 inches apart. This spacing is important to allow room for the cookies to spread slightly during baking.
Step 5: Bake
Place the baking sheet in the preheated oven and bake the cookies for 8 to 11 minutes until they’re lightly golden around the edges but still soft in the center. As soon as you take them out of the oven, press a frozen Reese’s into the center of each cookie while they are still warm, allowing the chocolate to melt slightly.
Step 6: Cool
Allow the cookies to cool on the baking sheet for about 15-20 minutes. This resting time helps the cookies set properly and makes them easier to transfer without breaking. After cooling, move the cookies onto a wire rack to cool completely before decorating.
Step 7: Decorate
Melt ½ cup of semi-sweet chocolate chips in a microwave-safe bowl in 20-second intervals, stirring until smooth. Use a squeeze bottle or a piping bag to draw spider legs on each cookie. Finally, attach candy eyeballs onto the melted chocolate before it sets, giving your Peanut Butter Spider Cookies their spooky, whimsical look!

Make Ahead Options
These Peanut Butter Spider Cookies are fantastic for meal prep, saving you precious time on busy days! You can prepare the cookie dough up to 24 hours in advance by mixing all the ingredients and storing the dough in an airtight container in the refrigerator. Additionally, you can unwrap the mini Reese’s and freeze them up to 3 days ahead to keep them firm during baking. When you’re ready to bake, just scoop the chilled dough onto a baking sheet, press in the frozen Reese’s, and follow the baking instructions as normal. This way, you’ll enjoy fresh cookies with minimal effort on the day you need them!

Correct Cooling Time: Let the cookies cool on the baking sheet for 15-20 minutes before moving them. This helps them set properly and prevents crumbling.
-
Use Fun Decorations: For best presentation, opt for colorful candy eyeballs as they add a festive touch and are sure to delight the kids!

Adjust Baking Time: Keep an eye on the cookies while baking; every oven is different. Remove them when they are just lightly golden for that perfect chewy bite.

Peanut Butter Spider Cookies Recipe FAQs
What type of peanut butter should I use for these cookies?
Absolutely! For these Peanut Butter Spider Cookies, I recommend using creamy peanut butter. It’s essential to avoid natural peanut butter, as it can affect the texture and consistency of your cookies. The creamy kind gives you that perfect soft and chewy base that everyone loves!
How should I store leftover cookies?
You can keep these monsters fresh by storing them in an airtight container at room temperature for up to 3 days. If you want them to last longer, feel free to refrigerate them for about 1 week, ensuring they’re wrapped up tight to prevent drying out.
Can I freeze Peanut Butter Spider Cookies?
Yes, indeed! To freeze these cookies, you have two options: you can freeze them before or after baking. For freezing before baking, shape the dough into balls, then place them on a baking sheet. Freeze until solid, then transfer them to a freezer-safe container for up to 3 months. When you’re ready to bake, add a couple of minutes to the baking time. If frozen after baking, let them cool completely first and then store them in an airtight container or freezer bag.
What if my cookies spread too much while baking?
Very! If your cookies spread too much, there are a couple of things to check. First, ensure your butter is at the right temperature; it should be softened but not melted. Overmixing the dough can also cause them to spread, so mix just until combined after adding the flour. Lastly, ensure you are chilling your mini Reese’s cups before pressing them in. If all else fails, consider baking a bit colder by turning down your oven by 25°F and keeping an eye on them!
Are these cookies safe for kids with allergies?
Absolutely! However, keep in mind that these cookies contain peanut butter and may not be suitable for kids with nut allergies. If you’re looking for alternatives, you could try almond butter for a nut-free option or even use sunbutter to cater to those with allergies. Always double-check ingredient labels for any hidden allergens!
Can I make these cookies vegan?
Yes, you can! To make these Peanut Butter Spider Cookies vegan, simply substitute the large egg with a flax egg. To do this, mix 1 tablespoon of ground flaxseeds with 2.5 tablespoons of water, let it sit for 5 minutes until it becomes gel-like, then mix it in with your wet ingredients. This simple swap allows everyone to join in on the spooky fun!
