Step‑by‑Step Instructions for Peanut Butter Spider Cookies
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your oven is at the perfect temperature for baking, which is crucial for achieving soft and chewy Peanut Butter Spider Cookies. While the oven heats, line a baking sheet with parchment paper to prevent sticking and make cleanup a breeze.
Step 2: Prepare the Reese’s Cups
Next, take the 24 mini Reese’s cups and place them in the freezer for about 30 minutes. Chilling the Reese’s will help them retain their shape when pressed into the cookies, ensuring they remain the delightful centerpiece for your Halloween treats.
Step 3: Cream the Butter and Sugar
In a large mixing bowl, beat together ½ cup of unsalted butter, ½ cup of brown sugar, and ½ cup of granulated sugar using an electric mixer on medium speed. Continue mixing for about 2-3 minutes until the mixture becomes light, fluffy, and well combined. This step is crucial for creating a rich, tender base for your Peanut Butter Spider Cookies.
Step 4: Add the Remaining Wet Ingredients
Now, mix in 1 cup of creamy peanut butter, 1 large egg, and 1 teaspoon of vanilla extract to your butter-sugar mixture. Beat until fully incorporated and smooth, taking about 1-2 minutes. This creamy blend will infuse your cookies with that delicious, nutty flavor that’s irresistible.
Step 5: 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 a pinch of salt. Gradually add this dry mixture to the wet ingredients, mixing on low speed just until everything is combined. Be careful not to overmix, as this can affect the texture of your Peanut Butter Spider Cookies.
Step 6: Form the Cookie Dough
Using a cookie scoop or tablespoon, scoop out portions of dough and roll them into balls about 1 inch in diameter. If desired, roll the balls in additional granulated sugar for a sweet crust. Place them evenly spaced on the prepared baking sheet, ensuring plenty of room for spreading while baking.
Step 7: Bake the Cookies
Place the baking sheet in the preheated oven and bake the cookies for 8 to 11 minutes, or until they are just lightly golden around the edges. The cookies will look slightly underbaked in the center, which is perfect for that soft, chewy texture we want in our Peanut Butter Spider Cookies.
Step 8: Cool and Press the Reese’s
Remove the cookies from the oven and let them cool for about 5 minutes on the baking sheet. While they are still warm, gently press a frozen mini Reese’s cup into the center of each cookie. This will create a delightful surprise for whoever bites into your spooky treats!
Step 9: Decorate with Spider Legs
While the cookies cool completely, melt ½ cup of semi-sweet chocolate chips in a microwave-safe bowl in 20-second intervals, stirring frequently until smooth. Using a squeeze bottle or piping bag, drizzle melted chocolate over each cookie to form spider legs. Attach candy eyeballs to the Reese’s cups using a dab of melted chocolate for an adorable finishing touch.
Peanut Butter Spider Cookies Variations
Customize your Peanut Butter Spider Cookies for even more fun and flavor!
Nut-Free: Swap peanut butter for sunflower seed butter, making it safe for kids with nut allergies while keeping the great taste.
Chocolate Lovers: Add chocolate chunks to the dough for extra richness and depth. Each bite will be an indulgent surprise!
Alternative Decor: Use mini chocolate chips or M&M’s for the spider eyes instead of candy eyeballs, giving your treats a different look. It’s a great way to change up the decorations while maintaining that fun element.
Texture Twist: Mix in chopped pecans or walnuts for a delightful crunch that complements the soft cookies beautifully. The combination of textures adds a wonderful surprise in every bite.
Spicy Kick: Incorporate a pinch of cayenne pepper into the dough for a subtle heat, elevating the flavor profile and making your cookies stand out!
Reese’s Variant: Instead of mini Reese’s cups, try using white chocolate-covered peanut butter cups for a lighter, sweeter take on the traditional design. It adds a creamy twist that’s sure to please.
Frosted Delight: After cooling, frost the cookies with a cream cheese frosting instead of melted chocolate for a rich and creamy finish. This extra layer will make your cookies truly unique and delectable.
Pumpkin Spice: For a seasonal twist, add a teaspoon of pumpkin spice to the dough. It’ll infuse your cookies with warm autumn flavors, perfect for Halloween gatherings.

Peanut Butter Spider Cookies Recipe FAQs
What type of peanut butter is best for the cookies?
I recommend using non-natural creamy peanut butter. Natural varieties can alter the texture of the cookies, making them less fluffy. Brands like Jif or Skippy work wonderfully for this recipe!
How should I store the Peanut Butter Spider Cookies?
These cookies can be stored in an airtight container at room temperature for up to 3 days to maintain their soft, chewy texture. For longer storage, keep them in the fridge for up to a week.
Can I freeze the Peanut Butter Spider Cookies?
Absolutely! To freeze, first let the cookies cool completely. Place them in a single layer on a baking sheet and freeze for about 1 hour. Then stack them with parchment paper in between layers in a freezer-safe container or bag. They will last up to 3 months.
What should I do if my cookies spread too much while baking?
If your cookies spread too much during baking, it may be due to soft butter or too-warm dough. Ensure your butter is at the right room temperature and refrigerate the dough for about 30 minutes before baking. This helps the cookies maintain their shape during baking.
Are these cookies safe for kids with peanut allergies?
Unfortunately, these Peanut Butter Spider Cookies are not safe for those with peanut allergies. To create a nut-free version, you can use sunflower seed butter instead of peanut butter. Just be aware that it may give a slightly different flavor.
How can I ensure my cookies will look uniform?
To achieve even sizes, using a cookie scoop is a game changer! This will help you portion out the dough perfectly, so every cookie bakes evenly and looks consistent on the platter.
