Peanut Butter Spider Cookies Ingredients
• Get ready for spooky fun!
For the Cookie Dough
- Unsalted Butter – Adds richness and moisture; ensure it’s at room temperature for easier blending.
- Brown Sugar – Provides sweetness and depth of flavor; dark brown sugar enhances that delightful molasses taste.
- Granulated Sugar – Sweetens and helps form a crisp outer shell; you can substitute with coconut sugar for a unique flavor twist.
- Creamy Peanut Butter – Gives the primary flavor and chewy texture; avoid natural varieties as they can impact cookie consistency.
- Large Egg – Binds ingredients and adds moisture; for a vegan option, consider using a flax egg or chia egg.
- Vanilla Extract – Enhances the overall flavor; always use pure vanilla extract for the richest taste.
- All-Purpose Flour – Provides structure to the cookies; feel free to substitute with gluten-free all-purpose flour (1:1).
- Baking Soda – Acts as a leavening agent for lightness; be sure it’s fresh for the best rise.
- Baking Powder – Works alongside baking soda for added lift; consider using both for better texture.
- Salt – Balances the sweetness while enhancing flavor.
For Decorating
- Granulated Sugar (for rolling) – Adds a sugary crust; this step is essential for that delightful texture.
- Mini Reese’s Peanut Butter Cups – Serve as the cute ‘eyes’ on the cookies; you can opt for other chocolate candies, but Reese’s carry that classic flavor.
- Semi-Sweet Chocolate Chips – Melted to create spider legs and attach candy eyes; dark chocolate can be substituted for a richer experience.
- Candy Eyeballs – Decorative element to complete the spider look, ensuring each cookie is a visual delight.
Step‑by‑Step Instructions for Peanut Butter Spider Cookies
Step 1: Preparation
Begin by chilling 24 mini Reese’s cups in the freezer to keep them firm during baking. While they chill, preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. This step ensures your Peanut Butter Spider Cookies will bake evenly and stick less to the surface.
Step 2: Cream Butter & Sugars
In a large mixing bowl, use a hand mixer or stand mixer to beat ½ cup of softened unsalted butter, ½ cup of brown sugar, and ¼ cup of granulated sugar together until the mixture is light and fluffy, about 2 to 3 minutes. This fluffy base creates the perfect texture for your cookies, giving them that delightful chewy bite.
Step 3: Combine Wet Ingredients
Add in ¾ cup of creamy peanut butter, 1 large egg, and 1 teaspoon of vanilla extract to the butter and sugar mixture. Mix until fully combined, scraping down the sides of the bowl as needed. The creamy consistency will enrich your Peanut Butter Spider Cookies with essential flavor and moisture.
Step 4: Incorporate Dry Ingredients
Gradually mix in 1¼ cups of all-purpose flour, ½ teaspoon of baking soda, ¼ teaspoon of baking powder, and a pinch of salt until just combined. Avoid overmixing to keep your cookies tender and soft after baking. You should see a thick cookie dough forming, free from dry flour patches.
Step 5: Shape Cookies
Using a tablespoon, scoop out portions of dough and gently roll them into balls. Roll each ball in granulated sugar for an added sugary crust, then place them on the prepared baking sheet, spaced about 2 inches apart. This helps them have room to spread while baking, ensuring perfect forming for your festive treats.
Step 6: Bake
Slide the baking sheet into the preheated oven and bake the cookies for 8 to 11 minutes. Look for the edges to be set but the centers to remain soft and slightly underbaked; they’ll continue cooking once removed from the oven. This helps achieve that classic chewy texture found in Peanut Butter Spider Cookies.
Step 7: Cool & Decorate
Allow the cookies to cool on the baking sheet for 15-20 minutes. Once cooled, press a frozen mini Reese’s cup into the center of each cookie. Melt ½ cup of semi-sweet chocolate chips in a microwave or double boiler, then use a piping bag or a fork to draw spider legs on each cookie and attach candy eyeballs. Your Peanut Butter Spider Cookies are now ready to amaze!

How to Store and Freeze Peanut Butter Spider Cookies

Expert Tips for Peanut Butter Spider Cookies

Perfectly Soft Centers: Remove the cookies from the oven when the edges are set but the centers are still soft. They’ll firm up as they cool.

Frozen Reese’s Trick: Keep the mini Reese’s cups frozen until you’re ready to press them into the cookies to prevent excessive melting during baking.

Peanut Butter Spider Cookies Recipe FAQs
How do I know when my peanut butter is ripe for baking?
Absolutely! When choosing peanut butter for these cookies, opt for a creamy variety to ensure a smooth texture. Avoid natural peanut butter with oil separation, as it can lead to inconsistent cookie texture. Look for well-stirred creamy options that will blend effortlessly into your dough.
What’s the best way to store leftover cookies?
Very! Store your Peanut Butter Spider Cookies in an airtight container at room temperature for up to 3 days. To keep them fresh and prevent sticking, I recommend placing a sheet of parchment paper between layers. If you prefer softer cookies, feel free to refrigerate them, where they can last up to a week.
Can I freeze the cookie dough?
You absolutely can! To freeze the dough, shape the cookie balls and place them on a baking sheet without rolling in sugar. Freeze until firm, then transfer them to an airtight container or freezer bag. They can be stored like this for up to 3 months. When you’re ready to bake, just pop them in the oven directly from frozen, adding an extra minute or two to the baking time.
What if my cookies come out too hard or too soft?
No worries! If your Peanut Butter Spider Cookies turn out too hard, it could be due to overbaking. Aim for the edges to be set while the centers look soft; they will firm up as they cool. On the other hand, if they’re too soft, it might be that the dough didn’t have enough flour or the cookies were underbaked. Make sure you’re leveling off flour and doing a quick bake test on a smaller batch if unsure.
Are these cookies safe for pets or those with allergies?
Great question! These cookies contain common allergens like peanuts and gluten, so they should be kept away from pets and those with allergies. If you need a safe alternative for your furry friends, consider peanut butter made specifically for dogs, and be sure to check for any added sugar or xylitol, which is harmful to them.
Can I make these cookies gluten-free?
Absolutely! To adapt your Peanut Butter Spider Cookies for a gluten-free diet, simply swap out the all-purpose flour for a 1:1 gluten-free flour blend. It’s essential to check that the blend includes xanthan gum, as this will help replicate the chewy texture of traditional cookies. Enjoy worry-free baking!
