Once October hits I am ready to make all of the seasonal treats and Halloween is the kickoff to my autumnal baking adventures. These Halloween Spider Cookies are one of my favorite things to make as the season turns spooky.

On the outside, these cookies are just so much fun and perfect for any Halloween party or as a pre-trick-or-treating treat. However, on the inside, they sport a smooth peanut butter mashup with two types of sugar and are topped with Reeses’ peanut butter cups — heavenly.
Crispy on top while creamy and chewy inside, they also bring a lot of texture to the table. And while they look cute (and like you took a ton of time to make them) they’re actually easy to assemble.
The next time you’re looking for Halloween recipes, consider these spooky spider cookies as a way to wow kiddos and grown-ups. This fun treat might be even more memorable than all of those crazy costumes!

Why You’ll Love Halloween Spider Cookies
Table of Contents
- Adorable – Adults and children alike will love these fun cookies with a just the right touch of Halloween creepiness.
- Tasty – These spooky cookies are just as delicious as they are cute!
- Easy – While there are a few steps to making these, it’s generally a simple recipe with ingredients you mostly have on hand already.
- Fun to make – If you have littles that like getting in on baking they can easily participate in making these treats.

Ingredients
- Creamy peanut butter – For this recipe, make sure to use creamy instead of crunchy peanut butter to get that smooth consistency in the dough.
- Unsalted butter – Make sure your butter is at room temperature so that it’s easy to mix.
- Light brown sugar – If you have dark brown sugar on hand, it will work — it just lends more molasses style flavor to the cookies.
- Sugar – Before baking, divide the sugar in half — some will be used in the batter and some will be used for the coating.
- Egg – Be sure to use a large sized egg.
- Vanilla or almond extract – Either of these will work well in this recipe. Use what you have on hand or whichever is your personal preference.
- Flour – All purpose flour will work best for this recipe.
- Baking soda – Make sure to get your measurements right for both the baking soda and the baking powder. While both are leavening agents, they do different jobs.
- Baking powder – Just a little of this ingredient will give the cookies just the right texture.
- Fine sea salt – Using a finer granule will help the salt to mix and dissolve more quickly.
- Mini Reese’s Cups – Making sure these candies are frozen is the key to them staying intact when you press them into the cookies that are hot out of the oven.
- Chocolate chips – You can choose whichever variety you like though I prefer using semi-sweet when I’m baking for the kiddos.
- Salted butter – For baked goods it’s typically recommended to use unsalted butter but for this recipe the bit of salt that’s in the butter will work perfectly and save the extra step of adding salt.
- Candy eyes – If you can find edible googly eyes (they’re available readily online) those are best, but any candy eyes will make these fun.

How To Make Halloween Spider Cookies
- Beat peanut butter, unsalted butter, light brown sugar, and ½ of the granulated sugar. Beat together until the mixture is completely smooth and creamy.
- Next, add the egg and the extract of your preference. Mix again.
- In a medium bowl, sift or whisk together the flour, baking soda, baking powder, and salt. Add the dry ingredients to the wet ingredients.
- After each addition, mix until the dry ingredients are incorporated and moist but be careful to avoid overmixing.
- While the peanut butter cookie dough is chilling, preheat the oven and prepare a baking sheet with parchment paper.
- Also, set the remaining ½ of the sugar aside in a separate bowl.
- When the cookie dough is ready, use a cookie scoop to measure out approximately a heaping tablespoon of it.
- Next, with clean hands, roll the dough into a ball. Then roll them in the sugar and place them onto the lined baking sheet.
- If your cookie sheet is small, you may need to use more than one. Ensure that the dough balls are far enough away from each other in the pan.
- Bake until the bottom edges are very lightly browned.
- When finished baking, remove the cookies from the oven and allow them to cool on the baking sheet.
- While the cookies fresh from the oven, gently press a miniature peanut butter cup into the top of each cookie. Make sure that the top (wide end) down is.
- Be careful to avoid pressing too hard so that the cookies do not crumble.
- Once you have pressed the peanut butter cups into the center of each cookie, use a spatula to move them to a wire rack.
- Allow the cookies to cool completely before decorating them.
- While the cookies are cooling, melt the chocolate chips with the salted butter. Though you could use a double boiler, you can also do this in the microwave at 20-second intervals.
- Be careful to ensure that you stir after each interval and continue reheating as necessary. Avoid overcooking the chocolate.
- Dip a toothpick into the melted chocolate and butter mixture.
- Dab the chocolate onto the back of each candy eyeball.
- Then, stick two eyeballs to the outside wall of each peanut butter cup, doing two per cookie.
- While the chocolate is setting, transfer the remaining melted chocolate into the piping bag, pastry bag, or a ziploc bag with a tiny piece cut off of the corner. Fitting the bags with a fine tip will work best.
- Pipe 4 chocolate legs on each side to make 8 legs total on each cookie.

Variations
- Black licorice – Instead of black frosting consider using black licorice strings to make the spider legs.
- Chocolate truffles – To make these a bit more fancy, try using small chocolate truffles instead of mini Reese’s peanut butter cups.
- Milk balls – Another alternative to the peanut butter cups is milk balls – these will lend a crunchiness to the cookies.
- Flour – If you have allergies to wheat, try using almond flour or coconut flour instead.
- Sugar alternatives – To lower the amount of sugar in the spider cookies, try using alternatives to standard sugar. You can find alternatives that use monk fruit, erythritol, or other options at your grocery store or online.
- Chocolate – For the legs you can substitute dark chocolate or milk chocolate as you prefer.
- Chocolate frosting – Instead of melting the chocolate with the butter you can use a prepared frosting instead.
- Sugar cookies – If there are peanut allergies, you can use a sugar cookie recipe instead of peanut butter cookie dough for the spider bodies.

Storage and Freezing
Store the cookies in an airtight container in the refrigerator for up to 5 days or you can freeze them for up to 2 months.
