Peanut Butter Spider Cookies are the ultimate Halloween treat—fun, festive, and packed with that classic peanut butter and chocolate combo everyone loves. These cookies start with a soft and chewy peanut butter base and are topped with a round chocolate candy to create the “body” of the spider. Add a few chocolate legs and candy eyes, and you’ve got a treat that’s both creepy and irresistibly delicious. They’re perfect for Halloween parties, school events, or a spooky movie night at home.

What Makes These Cookies Special?
These cookies combine rich, nutty peanut butter flavor with the visual flair of Halloween-themed decorating. The base is a classic peanut butter cookie that’s soft, chewy, and full of nostalgic flavor. Once baked, each cookie is topped with a chocolate truffle, peanut butter cup, or chocolate ball, which serves as the spider’s body. With melted chocolate piped into little legs and candy eyes added for personality, these cookies are both eye-catching and delicious.
They’re also surprisingly simple to make—especially fun for kids or group baking sessions.
Cooking Time
- Prep Time: 20 minutes
- Cook Time: 10 minutes
- Decorating Time: 15 minutes
- Total Time: 45 minutes
- Servings: 24 cookies
Ingredients
For the Peanut Butter Cookies:
- 1 ¼ cups all-purpose flour
- ½ tsp baking soda
- ¼ tsp salt
- ½ cup unsalted butter, softened
- ½ cup granulated sugar
- ½ cup packed brown sugar
- ¾ cup creamy peanut butter
- 1 large egg
- 1 tsp vanilla extract
For the Spider Decoration:
- 24 chocolate truffles or round chocolate candies (like Lindor truffles or peanut butter cups)
- ½ cup semisweet chocolate chips (for piping legs)
- Candy eyes (store-bought or homemade)
Instructions
1. Prepare the Peanut Butter Cookie Dough
Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
In a large mixing bowl, cream together the softened butter, granulated sugar, brown sugar, and peanut butter until light and fluffy. Beat in the egg and vanilla extract.
Gradually add the dry ingredients to the wet mixture until just combined.
2. Bake the Cookies
Scoop tablespoon-sized portions of dough, roll into balls, and place on the prepared baking sheets about 2 inches apart.
Flatten slightly with the palm of your hand or the bottom of a glass. Bake for 9–11 minutes, or until lightly golden and set.
Remove from the oven and immediately press a chocolate truffle into the center of each cookie while still warm. Allow the cookies to cool completely so the chocolate sets.
3. Decorate the Spiders
Melt the semisweet chocolate chips in a microwave-safe bowl in 20-second increments, stirring until smooth.
Transfer the melted chocolate to a piping bag or small zip-top bag with a corner snipped off.
Pipe 4 legs on each side of the chocolate “body.” Attach candy eyes using a tiny dab of melted chocolate as glue.
Let the decorations set fully before serving or storing.
