Step-by-Step Instructions
Each step below is carefully explained to ensure even beginner bakers can follow along with ease.
1. Preheat Your Oven
Set your oven to 350°F (175°C). Line two large baking sheets with parchment paper or silicone baking mats to prevent sticking and ensure even baking.
2. Cream the Butter and Sugars
In a large mixing bowl, use a hand or stand mixer to cream together the softened butter, granulated sugar, and brown sugar. Beat on medium speed until the mixture becomes light and fluffy, about 2 minutes.
3. Add Peanut Butter, Egg, and Vanilla
Add the peanut butter and mix until fully incorporated. Then add the egg and vanilla extract, beating until smooth and uniform. Scrape down the sides of the bowl to ensure everything is blended.
4. Combine Dry Ingredients Separately
In another bowl, whisk together the flour, baking soda, and salt. Gradually add this dry mixture into the wet ingredients, mixing on low speed until a soft dough forms.
5. Shape the Cookie Dough
Scoop out tablespoon-sized portions of dough and roll them into balls using your hands. Place them about 2 inches apart on your prepared baking sheets. Gently press down the tops of the dough balls to flatten them slightly—they will spread a bit as they bake.
6. Bake the Cookies
Bake the cookies in the preheated oven for 8 to 10 minutes, or until the edges are just beginning to set. Do not overbake—these cookies should remain soft in the center.
7. Press the Chocolate Bodies
Immediately after removing the cookies from the oven, gently press one chocolate candy ball into the center of each cookie. The heat will help set the candy slightly into the cookie, forming the “spider body.”
Allow the cookies to cool on the baking sheet for about 5 minutes, then transfer them to a wire rack to cool completely before decorating.
8. Prepare the Chocolate Legs
Melt your chocolate in a small heatproof bowl using a microwave (20-second intervals, stirring between) or over a double boiler. Transfer the melted chocolate to a piping bag fitted with a small round tip or use a zip-top bag with a tiny corner snipped off.
Pipe four legs on each side of the chocolate ball, extending outward like spider legs. Allow the chocolate to set at room temperature or refrigerate for 10 minutes if needed.
9. Attach Candy Eyes
Using a small dab of melted chocolate or icing as glue, stick two candy eyes onto the front of each chocolate ball. Press gently until they stick, then let the cookies sit until fully set.

Tips and Ingredient Substitutions
Nut-free option: Substitute peanut butter with sunflower seed butter or soy nut butter. Be aware that flavors will vary slightly.
Make-ahead tip: Cookie dough can be prepared and stored in the refrigerator for up to 48 hours before baking.
For a richer cookie: Add 2 tablespoons of cocoa powder to the dry ingredients for a chocolate-peanut butter variation.
Candy alternatives: Chocolate kisses or round chocolate truffles can be used if malt balls aren’t available.

Recipe Variations to Try
While these cookies are perfect as-is, here are some fun twists you can experiment with.
Chocolate Spider Cookies
Add ¼ cup of cocoa powder to the dough and use dark chocolate candies to create a chocolate lover’s version.
Mini Spider Cookies
Make smaller cookies using a teaspoon of dough and mini chocolate chips or smaller candies as the spider body.
Halloween Monster Mash
Use Halloween-colored M&Ms or sprinkles to decorate the base of the cookie along with the spiders for a more festive look.

Common Questions
Can I use natural peanut butter?
It’s possible, but natural peanut butter often has more oil separation and a looser texture. For best results, use a no-stir peanut butter that holds its shape.
What kind of chocolate is best for legs?
Use semisweet or dark chocolate for the best contrast and structure. Let the melted chocolate cool slightly before piping for sharper leg lines.
How can I make the candy eyes at home?
Use white royal icing or melted white chocolate for the whites. Once set, dot the centers with a toothpick dipped in melted dark chocolate or edible black gel.
Can I double the recipe?
Yes, the recipe scales easily. You can double the ingredients and bake in batches, just be sure not to overcrowd the baking sheet.
Conclusion
Peanut Butter Spider Cookies are the ultimate Halloween cookie—delightfully soft and chewy, creatively festive, and surprisingly easy to make. They’re sure to be the center of attention at any Halloween event or family gathering.
By using simple pantry ingredients and a little decorative flair, you can transform a classic cookie into a spooky treat that’s more cute than creepy. It’s also an ideal baking project to share with kids or friends during the Halloween season.
