These adorable Peanut Butter Spider Cookies bring amazing fun and flavor to any Halloween gathering or kids’ party. They bake up chewy, buttery, and nutty, and decorating them with chocolate and candy eyes adds giggles and joy to every bite. I make these every October with my little ones and they cannot wait to craft their own cookie spiders.
I first whipped these up for a school Halloween party and the smiles were priceless. Now we make them together most every year so everyone gets to join in the decorating.
Ingredients
- Unsalted butter: Choose butter at room temperature for best creaming and even consistency
- Creamy peanut butter: Opt for a well-stirred brand to avoid dry cookies
- Granulated sugar: Adds sweetness and helps cookies crisp
- Light brown sugar: Offers extra moisture and caramel notes
- Large egg: Use fresh eggs for richer flavor and binding
- Vanilla extract: Select pure vanilla for depth in dough
- All-purpose flour: Sift if possible for a delicate crumb and smooth dough
- Baking soda: Essential for a gentle rise and softer texture
- Salt: Balances sweetness and brings out the nutty flavor
- Mini chocolate peanut butter cups: Go for high-quality candies to hold their shape and flavor
- Semisweet chocolate chips: Melt smoothly and work great for piping legs
- Candy eyes: Adds whimsical charm and turns cookies into friendly spiders
Instructions

- Combine Dry Ingredients:
- Whisk all-purpose flour baking soda and salt in a separate bowl This makes sure leavening agents and salt are evenly distributed
- Mix Dry and Wet Mixtures:

- Portion the Dough:
- Scoop tablespoon-sized balls onto prepared baking sheets Space cookies about two inches apart for room to spread
- Bake the Cookies:
- Transfer sheets to the oven and bake at three hundred fifty degrees Fahrenheit for eight to ten minutes The edges should be set and just golden but the centers soft
- Add Peanut Butter Cups:
- Pull cookies out and immediately press a mini chocolate peanut butter cup into the center of each cookie Cool the cookies on the baking sheets for five minutes so cups set snugly
- Cool and Decorate:
- Move cookies to a wire rack to fully cool Transfer melted semisweet chocolate to a piping bag Snip a very small opening and gently pipe three to four legs on each side of the peanut butter cup for the spider legs
- Attach Candy Eyes:
- Using a dab of melted chocolate stick two candy eyes onto the top of each peanut butter cup Allow chocolate legs and eyes to set before serving for best results

My favorite part is pressing those tiny candy eyes into the warm chocolate With my daughter at my elbow we always laugh at how some spiders look surprised and some look sleepy The peanut butter aroma brings back so many autumn memories from when my sons were tiny and sneaking tastes from the mixing bowl
Storage Tips
Keep cookies in an airtight container on your counter for up to four days They stay soft as long as you seal them quickly after decorating For longer storage freeze baked undecorated cookies for up to three months Defrost at room temperature decorate and enjoy fresh flavors
Ingredient Substitutions
Try sunflower seed butter in place of peanut butter for a nut free version You can swap mini chocolate truffles or plain chocolate buttons if peanut butter cups are not available Decorating works equally well with white or dark chocolate chips
