How to Make Peanut Butter Spider Halloween Cookies
-
Prepare the sheets: Line two cookie sheets with parchment paper and set them aside, ensuring a non-stick surface for your cookies to bake perfectly.
-
Mix dry ingredients: In a medium-sized bowl, whisk together the flour, baking soda, and salt. This helps to evenly distribute the leavening agent for fluffy cookies.
-
Cream butter and sugars: In a separate large bowl, cream together the room temperature butter, light brown sugar, and granulated sugar. Mix until light and fluffy, about 2-3 minutes, to create a lovely base.
-
Incorporate peanut butter: Add the smooth peanut butter and mix until combined, achieving a creamy and fluffy texture that smells divine.
-
Add egg and vanilla: Crack in the egg and pour in the vanilla extract. Mix well, scraping down the sides to ensure everything is blended beautifully.
-
Mix in milk and dry ingredients: Pour in the milk and blend until there are no lumps. Then gently fold in the dry ingredients until just combined to avoid overmixing.
-
Chill the dough: Cover the bowl with plastic wrap and chill the dough in the fridge for at least 2 hours or overnight. This step is crucial for the best texture!
-
Preheat the oven: Once dough has chilled, preheat your oven to 375°F, ensuring the cookies will bake evenly.
-
Scoop the dough: Using a cookie scoop or tablespoon, scoop the dough into 2 Tbsp. balls and place them 2 inches apart on the prepared cookie sheet.
-
Bake the cookies: Bake in the preheated oven for 10-12 minutes or until they turn golden brown. The aroma will make your kitchen feel like a cozy bakery!
-
Add Reese’s cups: Allow the cookies to sit on the hot sheet for 3-5 minutes before gently pressing a Reese’s peanut butter cup on top of each cookie.
-
Cool on wire rack: Transfer the cookies to a wire rack to cool completely, creating the perfect texture for decorating.
-
Melt chocolate: In a microwave-safe bowl, melt the semi-sweet chocolate in 30-second intervals, stirring until completely smooth and melted.
-
Decorate with legs: Use a piping bag to pipe eight chocolate legs extending from the sides of the Reese’s cup to the edge of the cookie. Have fun with this creative step!
-
Glue on candy eyes: Finally, use the melted chocolate to secure two candy eyes on each spider, placing them on the sides of the Reese’s cup for that whimsical touch.
Optional: Drizzle extra melted chocolate over the cookies for added deliciousness!

Expert Tips for Peanut Butter Spider Halloween Cookies
Chill Time Matter: Always chill the dough for at least 2 hours. This will prevent spreading and ensure a chewy, thick cookie texture.
Don’t Overmix: Combine the dry ingredients until just incorporated to keep your cookies soft and tender. Overmixing can lead to a tough result!
Hot Cookie Sheet: Allow cookies to sit on the hot sheet before adding the Reese’s cups, as this helps them stick better and melt slightly for a gooier treat.
Decorating Fun: Let kids help decorate with the chocolate legs and candy eyes! This not only makes them more enjoyable to make but adds a personal touch to your Peanut Butter Spider Halloween Cookies.
Experiment with Shapes: If you’re feeling adventurous, try different candies or cookie cutters to create various designs. The possibilities are endless!
Make Ahead Options
These Peanut Butter Spider Halloween Cookies are perfect for busy home cooks looking to save time without compromising flavor! You can prepare the cookie dough up to 24 hours in advance by chilling it in the fridge, ensuring it remains fresh and flavorful. For the best results, keep the dough tightly wrapped in plastic wrap to prevent it from drying out. Additionally, you can also melt the chocolate for the spider legs ahead of time and store it in an airtight container at room temperature. When ready to bake, simply scoop the dough onto the prepared sheets, bake, and then add your Reese’s peanut butter cups and charming candy eyes for that delightful presentation. This way, you’ll have homemade treats ready to wow your guests with minimal effort!
How to Store and Freeze Peanut Butter Spider Halloween Cookies
Room Temperature: Store cookies in an airtight container at room temperature for up to 3 days. This keeps them soft and fresh, ready to devour!
Fridge: If you need to extend their shelf life, place the cookies in the fridge for up to 5 days. Make sure they’re in an airtight container to prevent them from drying out.
Freezer: For longer storage, freeze in a single layer on a baking sheet until solid, then transfer to a freezer-safe bag for up to 3 months. Thaw in the fridge before enjoying again.

Peanut Butter Spider Halloween Cookies Recipe FAQs
How do I choose ripe ingredients for this recipe?
Absolutely! For the best cookies, your butter should be at room temperature, which makes it easier to cream with the sugars. Look for butter that’s soft but not melted. As for your peanut butter, choose a smooth variety that’s free from added sugars or oils for the most authentic flavor.
What’s the best way to store Peanut Butter Spider Halloween Cookies?
These delightful cookies can be stored in an airtight container at room temperature for up to 3 days. Make sure they’re completely cool before sealing to maintain their fantastic texture.
Can I freeze Peanut Butter Spider Halloween Cookies?
Absolutely! To freeze, place the cookies in a single layer on a baking sheet until they’re solid. Then, transfer them to a freezer-safe bag for up to 3 months. Thaw them in the fridge overnight when you’re ready to indulge again, and microwave for about 10-15 seconds to regain that freshly-baked warmth.
What should I do if my cookie dough is too sticky?
No worries! If your dough is too sticky to scoop, you can add a little bit of flour, about 1 tablespoon at a time until it’s workable. Make sure to chill the dough properly; a well-chilled dough is less sticky and easier to handle.
Are there any dietary considerations for these cookies?
Very much so! If you’re baking for someone with peanut allergies, consider using a sun butter or soy nut butter alternative. Keep in mind that Reese’s cups contain milk and peanuts, so if you’re catering for dietary restrictions, use dairy-free chocolate and decorations accordingly.
Can I use other candies for the decorations?
The more the merrier! Feel free to get creative with your toppings! Use different types of candy bars or even gummy treats to turn your cookies into unique spooky designs. Just make sure they are suitable for your guests’ tastes and dietary needs!
