Step‑by‑Step Instructions for Peanut Butter Spider Halloween Cookies
Step 1: Prepare the Dough
In a spacious mixing bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, and a pinch of salt until evenly combined. In another bowl, cream together ½ cup of unsalted butter, ½ cup of light brown sugar, and ½ cup of granulated sugar until the mixture is fluffy and pale, about 3-4 minutes. Stir in 1 cup of smooth peanut butter, then add 1 beaten egg, 1 teaspoon of vanilla extract, and 2 tablespoons of milk, mixing until smooth. Gradually incorporate the dry ingredients into the wet mixture until just combined.
Step 2: Chill the Dough
Once the dough is well mixed, cover the bowl tightly with plastic wrap and refrigerate for at least 1 hour. Chilling is crucial for the Peanut Butter Spider Halloween Cookies as it helps the dough firm up, preventing them from spreading too much during baking. While the dough chills, take a moment to preheat your oven to 350°F (175°C), ensuring it’s ready to perfectly bake those delightful cookies.
Step 3: Shape Cookies
After the chilling period, remove the dough from the refrigerator and use a cookie scoop or tablespoon to portion it out into balls—about 1.5 inches in diameter. Line two baking sheets with parchment paper, placing each ball at least 2 inches apart to allow for spreading. This spacing ensures each Peanut Butter Spider Halloween Cookie retains its shape while baking, creating that lovely golden edge.
Step 4: Bake
Slide the baking sheets into your preheated oven and bake the cookies for 10-12 minutes, or until the edges have turned golden brown while the centers appear slightly soft. Allow the cookies to cool on the sheets for 3-5 minutes before transferring them to a wire rack. This cooling time is vital, as it allows the cookies to set properly while preventing breakage when moving them.
Step 5: Decorate
Once the cookies are fully cooled, take a miniature Reese’s Peanut Butter Cup and gently press it into the center of each cookie, ensuring it sticks well. For the spooky spider decoration, melt some semi-sweet chocolate in a microwave-safe bowl at 15-second intervals until smooth. Use a piping bag or a ziplock with the corner snipped off to pipe spider legs on each cookie and adhere candy eyes. Refrigerate briefly to let the chocolate set before serving these festive Peanut Butter Spider Halloween Cookies.

Expert Tips for Peanut Butter Spider Halloween Cookies
• Chill the Dough: Ensure the dough is thoroughly chilled for at least 1 hour; this prevents flat cookies and promotes a soft, chewy texture.
• Use Quality Peanut Butter: Opt for creamy peanut butter like Skippy for the best texture; natural nut butters can lead to drier cookies that aren’t as enjoyable.
• Don’t Skip Cooling: After baking, let the cookies cool on the baking sheet for 3-5 minutes. This helps them set properly and avoids breakage.
• Perfect Spacing: Space the cookie balls at least 2 inches apart on the baking sheet to allow for even spreading and maintain their shape during baking.
• Creative Decorations: Get playful with your decorations! Feel free to swap Reese’s with your favorite candies or use white chocolate for spider legs to mix things up.
How to Store and Freeze Peanut Butter Spider Halloween Cookies
Airtight Container: Store cookies in an airtight container at room temperature for up to 1 week to keep them fresh and chewy.
Refrigeration: For longer freshness, store them in the fridge for up to 2 weeks. Just use parchment paper between layers to prevent sticking.
Freezer: Freeze cookies in a single layer on a baking sheet until solid, then transfer to a freezer bag for up to 3 months.
Reheating: When ready to enjoy, thaw cookies on the counter for a couple of hours, or heat in the microwave for 10-15 seconds for a freshly-baked experience.
