Peanut Butter Spider Halloween Cookies Ingredients
• Get ready to create some creepy and delicious treats!
For the Cookie Dough
- All-Purpose Flour – Provides structure to the cookies; you can use a gluten-free flour blend for a gluten-free version.
- Baking Soda – Acts as a leavening agent for a delightful rise; no need for substitutions.
- Salt – Balances flavors beautifully; opt for kosher or sea salt for best results.
- Unsalted Butter – Ensures rich, moist cookies; substitute with coconut oil or vegan butter for a dairy-free option.
- Light Brown Sugar – Adds moisture and a hint of molasses; granulated sugar works in a pinch for a less moist cookie.
- Granulated Sugar – Sweetens the mix and contributes to crispiness.
- Smooth Peanut Butter – Offers delectable flavor and moisture; creamy works best, while crunchy may alter the cookie’s texture.
- Egg – Binds the ingredients for a perfect cookie; use flaxseed meal mixed with water for a vegan alternative.
- Vanilla Extract – Introduces a depth of flavor; feel free to omit if you’re running low.
- Whole Milk – Adjusts dough texture and moisture; almond milk or oat milk makes it dairy-free.
For the Spider Decoration
- Miniature Reese’s Peanut Butter Cups – Serve as the spider’s body; any chocolate candy, like Whoppers or Hershey Kisses, can substitute.
- Semi-Sweet Chocolate – Used to pipe spider legs and attach decorations; choose dark or milk chocolate based on your personal preference.
- Candy Eyes – Add a fun touch to your spiders; you can replace them with chocolate chips if necessary.
Now that you have everything ready, let’s embark on a spooky baking adventure! 🌟
Step‑by‑Step Instructions for Peanut Butter Spider Halloween Cookies
Step 1: Prep Dough
In a large mixing bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of salt until well combined. In another bowl, cream ½ cup unsalted butter with ¾ cup light brown sugar and ½ cup granulated sugar until fluffy and light in color. Gradually mix in 1 cup of smooth peanut butter until smooth, followed by 1 egg, 2 tablespoons of whole milk, and 1 teaspoon of vanilla extract. Combine wet and dry ingredients until a dough forms.
Step 2: Chill Dough
Cover the cookie dough with plastic wrap and place it in the refrigerator for at least 1 hour. Chilling the dough is crucial in achieving the perfect texture for your Peanut Butter Spider Halloween Cookies, preventing them from spreading too much while baking. Once the dough is firm, it’s time to shape those adorable cookies.
Step 3: Shape Cookies
Preheat your oven to 350°F (175°C) while you prepare the cookies. Line a baking sheet with parchment paper for easy cleanup. Scoop tablespoon-sized balls of the chilled dough onto the baking sheet, spacing them about 2 inches apart to allow for spreading. The dough should feel slightly sticky but manageable, which ensures a soft and chewy cookie once baked.
Step 4: Bake
Bake the cookies in the preheated oven for 10-12 minutes, or until the edges are set and just starting to turn golden but the centers still look soft. When you remove the cookies, they will continue cooking slightly on the baking sheet, giving you that perfect chewy texture in the Peanut Butter Spider Halloween Cookies. Let them cool for about 3-5 minutes on the baking sheet before transferring them to a wire rack.
Step 5: Decorate
Once the cookies are slightly cooled, place a miniature Reese’s Peanut Butter Cup right in the center of each cookie to resemble the body of a spider. Allow the cookies to cool completely as you prepare your chocolate for decorating. Melt ¼ cup of semi-sweet chocolate in a microwave-safe bowl in 20-second intervals, stirring until smooth for creating spider legs and attaching candy eyes.
Step 6: Chill Again
Use the melted chocolate to pipe legs onto each cookie, extending from the Reese’s Peanut Butter Cup. Then, gently attach two candy eyes for a fun finish! Once decorated, refrigerate the cookies for about 15-20 minutes to set the chocolate and ensure everything holds together nicely. Your Peanut Butter Spider Halloween Cookies are now ready to thrill everyone at your spooky gathering!

What if my cookies turn out too flat?
If you find your Peanut Butter Spider Halloween Cookies are spreading too much while baking, it’s likely the dough was not chilled long enough. Be sure to refrigerate the dough for at least 1 hour before shaping the cookies. Additionally, using too much butter or not measuring accurately can lead to flat cookies, so ensure that all ingredients are precisely measured.
Are there any allergy considerations I should keep in mind?
Yes! Since this recipe contains peanuts, those with nut allergies should avoid these cookies. You can substitute peanut butter with sun butter or another nut-free alternative to keep it inclusive for everyone. Always double-check the candy you use for decorations, as they may contain allergens such as dairy or soy.
Can the cookies be decorated differently?
