Ingredients You’ll Need

All these ingredients come together to make a cookie that’s buttery, peanut buttery, and just sweet enough — and the decorating components turn them into spooky little critters you’ll want to eat right away. When shopping, fresh peanut butter and good quality melting chocolate really make a difference in taste and texture.

• Unsalted Butter: Using unsalted butter lets you control the saltiness and keeps the flavor buttery and pure.
• Light Brown Sugar: Packs moisture and a hint of caramel flavor into the dough.
• Sugar (granulated and for rolling): Adds sweetness and helps achieve a slight crisp on the cookie edges.
• Creamy Peanut Butter: The star ingredient — creamy is easier to blend smoothly into the dough.
• Eggs + Egg Yolk: Provide structure and richness without drying the cookies out.
• Vanilla Extract: A little vanilla always enhances sweetness and rounds out flavors.
• All-Purpose Flour: The base of the dough, for that soft yet sturdy texture.
• Corn Starch: Helps tenderize the cookie and prevent toughness.
• Baking Soda and Salt: For lift and flavor balance.
• Dark Chocolate Melting Wafers: Best for smooth melting and easy piping on decorations.
• Mini Marshmallows: The most fun part — used for creating those perfect cobwebs.
• Mini Reese’s Peanut Butter Cups: The cute spider bodies — chilling them before use is key so they don’t melt.
• Small Candy Eyes: Adds personality to your spiders — irresistible and a total hit with kids!

Variations

I love playing around with these cookies — feel free to make this recipe yours! Whether you want to swap peanut butter for almond butter or make it nut-free with sunflower seed butter, there’s a way to customize. You can also vary the spooky decoration based on whatever candies you have on hand.

• Nut-Free Variation: Substitute the peanut butter with a sunflower seed butter, and make sure to use allergy-friendly chocolate and candies; my niece’s friends with allergies still gobbled these up!
• Spooky Decoration Swap: Instead of mini Reese’s cups, try using small candy pumpkins or gummy spiders for a colorful change.
• Vegan Option: Use vegan butter and egg replacer, and double-check the marshmallows as they often contain gelatin — vegan marshmallows are available online.
• Chocolate Chip Variation: For a quicker version, just press mini chocolate chips in the centers and pipe spider legs with melted chocolate.

How to Make Spooky Spider Cookies Recipe

Step 1: Cream the Butter and Sugars to Perfection

Start by beating the softened unsalted butter with both the light brown sugar and granulated sugar in your stand mixer or hand mixer for about a minute until everything looks well combined and fluffy. This crucial step traps air and ensures your cookies turn out soft and tender instead of dense. I always scrape the bowl once or twice here to keep the mixture even.

Step 2: Add the Peanut Butter, Eggs, and Vanilla

Mix in the creamy peanut butter until smooth, then add your eggs and the extra egg yolk one at a time. Pause after each addition to scrape down the sides of the bowl — this keeps everything well-incorporated. Lastly, stir in the vanilla extract; this little splash really brightens up the flavor.

Step 3: Whisk Together the Dry Ingredients and Combine Gently

In a separate bowl, whisk the all-purpose flour, corn starch, baking soda, and salt. Gradually add this dry mix to the peanut butter batter, mixing just enough to combine. I learned that overmixing can make cookies tough, so keep it gentle and scrape the bowl again to catch any stray flour pockets.

Step 4: Chill the Dough to Prevent Flat Cookies

Pop the dough into the fridge for at least 30 minutes. This step is a game-changer, especially for peanut butter cookies that tend to spread. If you find your cookies are too flat after baking, give the dough a longer chill time — I sometimes chill mine for a full hour and it makes a big difference.

Step 5: Form and Bake Your Cookies

Preheat to 375°F (190°C) and prep your baking sheets with parchment paper. Roll out the chilled dough into 1 ½ tablespoon-sized balls, then roll each in the granulated sugar — this adds a perfect slight crunch on the outside. Space the dough balls at least two inches apart. Bake for 8-10 minutes; I usually pull mine at 9 minutes for that soft center. Let them cool on the tray for 5 minutes before the next step.

Step 6: Press in the Mini Reese’s Peanut Butter Cups

While the cookies are still warm but cooled a bit (~5 minutes), gently press a chilled mini Reese’s peanut butter cup into the center of each cookie. Keeping the candies cold is key to avoid melting. Then let the cookies cool completely on the sheet so the candy settles nicely without sliding off.

Step 7: Create the Marshmallow Cobwebs

Place about ¼ cup of mini marshmallows in a microwave-safe bowl. Heat for about 10 seconds — they should start puffing but not melt completely. Stir, then pinch and stretch the sticky marshmallow with your fingers to drape web-like strands over the cooled cookies. The marshmallow sets fast, so work quickly and refresh with new marshmallows as needed. This technique adds the perfect spooky “cobweb” effect and is always a hit.

Step 8: Pipe on the Chocolate Spider Legs and Eyes

Melt your dark chocolate wafers according to package directions and let them cool about 5 minutes — if too hot, the piping gets messy. Pour the melted chocolate into a small zip-top bag and snip a tiny corner. Pipe a small dab of chocolate on top of each peanut butter cup to act as glue, then immediately place two candy eyes on it. Next, pipe four thin “legs” on each side of the cup to turn your cookie into a creepy spider. Take your time here — this is where the cookies really come to life!

How to Serve Spooky Spider Cookies Recipe

Garnishes

I like adding a few extra candy eyes scattered on the serving platter and a dusting of powdered sugar for a “misty graveyard” look. If you want to up the spooky vibe, scatter some edible glitter or place the cookies on a bed of crumbled chocolate cookie crumbs as “dirt.”

Side Dishes

These cookies are fantastic with a glass of cold milk or a cup of spiced hot chocolate. If you’re hosting a Halloween party, pairing them with pumpkin-flavored muffins or apple cider donuts adds a nice seasonal spread.

Creative Ways to Present

Last year, I placed these spider cookies on mini paper plates decorated with fake spider webs and added some plastic spiders for dramatic effect — kids went nuts for it! You could also serve them on a dark-colored platter with orange and black napkins or put each cookie inside a mini cupcake liner to keep them from sticking together during a Halloween potluck.

Make Ahead and Storage

Storing Leftovers

Once decorated, store these cookies in an airtight container at room temperature for up to 3 days. I like to layer them with parchment paper between cookies to keep the spider legs intact and prevent sticking.

Freezing

If you want to make these ahead, freeze the baked but undecorated cookies in a single layer on a tray first. Once frozen, transfer them to a zip-top bag and store for up to 2 months. Decorate just before serving for best results — marshmallows and chocolate decorations don’t freeze well.

Reheating

I usually don’t reheat because these cookies are best fresh, but if you want that just-baked warmth, pop them in the microwave for 10-15 seconds. Avoid reheating after decorating, as the marshmallows might melt and the chocolate can soften too much.
