Embrace the Halloween Spirit with Homemade Treats
There’s something truly special about Halloween, isn’t there? The crisp autumn air, the vibrant decorations, the excitement of trick-or-treating, and of course, the cozy tradition of cuddling up with a good spooky movie like Hocus Pocus while waiting for little ghosts and goblins to arrive. For years, my Halloween celebrations mostly revolved around whipping up festive cocktails – like a mysterious Absolut Elyx Black Magic Martini or a whimsical Butterbeer Cocktail – paired with a hearty batch of spicy chili. Delicious, certainly, but this year, I felt a creative spark ignite within me to broaden my Halloween culinary horizons.

And so, I embarked on a mission to create a dessert that was not only incredibly sweet and flavorful but also undeniably adorable and perfectly on-theme for Halloween. The result? These show-stopping Peanut Butter Spiderweb Cookies! They represent a delightful step outside my usual holiday repertoire, proving that even a non-baker can craft something truly memorable for the spooky season. There’s an unparalleled joy in offering homemade treats, especially when they’re as visually striking and delicious as these cookies. They add a personal, charming touch to any Halloween gathering, making guests feel truly celebrated.

The Irresistible Charm of Peanut Butter Cookies
As the leaves begin to turn and the days grow shorter, my cravings for rich, comforting flavors intensify. And without fail, peanut butter invariably makes a much more regular appearance in my pantry and my diet. Its rich, creamy texture and distinctly nutty flavor are simply perfect for the autumn months. It pairs beautifully with freshly harvested apples for a simple snack, but it truly shines in baked goods, offering a depth of flavor that’s both satisfying and nostalgic. Is there anything quite as comforting as a freshly baked, perfectly chewy peanut butter cookie, especially when accompanied by a tall, frosty glass of milk? It’s a dreamy bite after another, a pure moment of bliss that transports you back to childhood.

These Peanut Butter Spiderweb Cookies truly embody everything wonderful about a classic peanut butter cookie. They’re soft, delightfully chewy, and packed with that signature deep, nutty flavor that everyone adores. They’re the ideal way to kick off the holiday baking season early, combining a beloved treat with a fun, festive twist. Beyond their seasonal appeal, these cookies are incredibly versatile – perfect for school lunchboxes, party platters, or simply as a cozy evening indulgence. Their inherent deliciousness makes them a crowd-pleaser, ensuring that every cookie disappears quickly, leaving only crumbs and happy smiles.

Why Quality Flour Matters for the Perfect Bake
The funny thing about baking is that you might not realize the immense impact of high-quality ingredients until you experience the difference firsthand. This is particularly true for flour, the backbone of almost any baked good. That’s precisely why I wholeheartedly recommend Bob’s Red Mill Organic All Purpose Unbleached White Flour for these peanut butter cookies, and frankly, for all your baking adventures. Whether you’re a seasoned baker or just starting your journey, choosing the right flour is paramount to achieving consistent, delicious results.

Bob’s Red Mill flour is my trusted staple because it consistently delivers. From delicate cakes to robust breads, and even sturdy pizza crusts, it performs flawlessly every single time. For these Peanut Butter Spiderweb Cookies, using a premium unbleached flour like this is absolutely essential to achieve that coveted chewy texture without compromising on flavor. The consistency and quality of the flour directly contribute to the cookie’s structure and mouthfeel, ensuring each bite is perfectly soft and satisfying. It’s not just about mixing ingredients; it’s about crafting a perfect balance, and a good flour makes all the difference.

Beyond its superior performance in the kitchen, Bob’s Red Mill Organic All Purpose Unbleached White Flour offers additional benefits that align with many dietary preferences and values. It’s proudly kosher, making it suitable for a wider audience. Moreover, it’s vegan, meaning it contains no animal-derived ingredients, a crucial consideration for plant-based diets. And for those who prioritize natural and sustainable products, it’s USDA certified organic, ensuring it meets strict organic farming standards. This combination of quality, versatility, and ethical considerations makes it my go-to choice for all baking needs, guaranteeing that your Peanut Butter Spiderweb Cookies will be nothing short of perfection.
Mastering the Art of Spiderweb Decoration (Easier Than You Think!)
Now, I know what some of you might be thinking: “Spiderweb icing? That sounds incredibly intricate and difficult!” Let me put those worries to rest right here and now, because I can assure you, with absolute confidence, that you CAN pull off this impressive decoration. The beauty of these Peanut Butter Spiderweb Cookies lies not only in their taste but also in the deceptively simple technique used to create their iconic spooky topping. You absolutely do not need to be a professional decorator to achieve these stunning results.

First and foremost, the royal icing itself is ridiculously straightforward to prepare. With just a few common ingredients and a stand mixer, you’ll have a perfectly smooth, glossy icing ready for decorating in minutes. The real magic, however, happens when you apply it. The decorating process is a two-step wonder: you’ll begin by spreading a smooth, even layer of white royal icing over the surface of each completely cooled peanut butter cookie. This provides the perfect blank canvas for your arachnid artistry. Don’t worry about perfection; a rustic charm is part of the fun!
Next comes the artistic part, which is far easier than it looks. While the white icing is still wet, you’ll pipe a small black dot directly in the center of the cookie. From that central dot, you’ll then create a black spiral, working your way outwards towards the edge of the cookie. It doesn’t need to be perfectly symmetrical – the more organic, the better! The final step, the true “wow” factor, involves a simple wooden toothpick. Starting from the center black dot, gently drag the toothpick outwards towards the edge of the cookie, pulling the black icing through the white. Repeat this motion several times, evenly spaced around the cookie, creating radial lines that transform the spiral into a mesmerizing spiderweb pattern. And just like that, VOILA! You’ll have perfect, spooky spiderwebs ready to impress at whatever ghoulish gathering you have planned for the weekend. The contrast of the white and black, combined with the elegant web design, makes these cookies truly eye-catching. Have a SPOOK-tacular weekend, and enjoy your beautifully decorated treats!

Essential Tools for Spooky Success
To make your baking and decorating experience as smooth and enjoyable as possible, having the right tools on hand can make a world of difference. While some items are simply helpful, others are truly “must-haves” for achieving the perfect Peanut Butter Spiderweb Cookies. Investing in a few key pieces of equipment can elevate your baking game and ensure consistent, professional-looking results.
- Stand Mixer: My go-to for effortlessly combining doughs and whipping up icing is a sturdy stand mixer. It frees up your hands, ensures thorough mixing, and helps achieve that creamy, smooth texture for both your cookie dough and royal icing. If you don’t have a stand mixer, don’t fret! A good set of mixing bowls and an electric hand mixer will work perfectly fine, requiring a bit more arm work but delivering equally delicious results.
- Half Sheet Baking Pans & Silicone Mats: For perfectly golden and evenly baked cookies, I highly recommend using your favorite half sheet baking pans. Pairing them with silicone baking mats or parchment paper ensures that your cookies won’t stick, promotes even heat distribution, and makes cleanup an absolute breeze. This combination helps achieve that desired chewy texture without over-baking the edges.
- Wooden Toothpicks: Believe it or not, the secret to those intricate-looking spiderwebs is incredibly simple: wooden toothpicks! These humble tools become your magic wand for dragging the black icing through the white, creating the delicate web pattern. They offer precision and control, allowing you to create beautiful designs with minimal effort.
- Large Clear Squeeze Bottles: For applying the royal icing, both white and black, I find large clear squeeze bottles to be a fantastic alternative to traditional piping bags. They are much easier to fill, offer excellent control for piping dots and spirals, and are reusable and less messy than disposable bags. They’re particularly helpful for beginners who might find piping bags a bit tricky to maneuver, ensuring smooth and consistent lines for your spiderweb design.
With these essential tools by your side, you’re well-equipped to bake and decorate these festive Peanut Butter Spiderweb Cookies with confidence and ease!

Peanut Butter Spiderweb Cookies Recipe
equipment
-
KitchenAid Stand Mixer
-
Nordic Ware Natural Aluminum Commercial Baker’s Half Sheet
-
MontoPack Bamboo Wooden Toothpicks
-
Two Large Clear Squeeze Bottle
ingredients
- 1 cup unsalted butter room temperature
- 3/4 cup granulated sugar
- 1 cup light brown sugar
- 2 eggs
- 1 1/2 tsp vanilla extract
- 1 1/4 cup creamy peanut butter
- 3 cups + 2 Tbsp all-purpose flour
- 1 tsp baking soda
- 1 tsp baking powder
- 1/4 tsp salt
- 2-3 egg whites
- 1 tsp vanilla extract
- 4 cups confectioners’ sugar
- 1-2 tsp black food coloring
instructions
-
In the bowl of a stand mixer, cream together softened butter and both granulated and brown sugars until light and fluffy. Add the eggs one at a time, beating well after each addition until fully combined. Scrape down the sides of the bowl to ensure all ingredients are incorporated. Then, add the vanilla extract and creamy peanut butter, beating again until the mixture is smooth and well-blended.
-
In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. Gradually add the dry ingredients to the wet mixture in the stand mixer, mixing on low speed until just combined. Be careful not to overmix the dough. Once combined, cover the bowl tightly with plastic wrap and refrigerate for at least 2 hours. This chilling process helps the cookies maintain their shape and develop a richer flavor.
-
When you’re ready to bake, preheat your oven to 350°F (175°C). Prepare two baking sheets by lining them with silicone mats or parchment paper. This prevents sticking and ensures even baking.
-
Take the chilled cookie dough from the refrigerator. Roll approximately 1 1/2 to 2 tablespoons of dough into smooth balls. Place these dough balls onto the prepared rimmed baking sheets, ensuring there’s enough space between them for spreading.
-
Bake the cookies for 12 to 15 minutes, or until the edges are lightly golden and the centers are set. Once baked, remove the sheets from the oven and let the cookies cool on the baking sheets for about 10 minutes before carefully transferring them to wire cooling racks to cool completely. It’s crucial that the cookies are fully cooled before icing.
-
To prepare the royal icing, combine the egg whites and vanilla extract in a large bowl of a stand mixer. Beat on medium speed until the mixture becomes frothy. Gradually add the confectioners’ sugar, mixing on low speed until the sugar is completely incorporated and the mixture is shiny. Increase the speed to high and continue beating for approximately 5 to 7 minutes, or until the mixture forms stiff, glossy peaks. Once stiff peaks are achieved, remove about 1/3 of the white icing and transfer it to a smaller, separate bowl.
-
To the smaller bowl containing 1/3 of the royal icing, add black food coloring, starting with 1/2 teaspoon at a time. Mix thoroughly until you reach your desired shade of deep black. Transfer this black icing into a small piping bag or, for easier handling, a clear squeeze bottle, and set it aside.
-
Once the cookies are completely cool, gently spoon a small amount of the white royal icing onto the center of each cookie. Using the back of a spoon or a small offset spatula, carefully smooth the icing into a uniform circle, covering the top surface of the cookie. Ensure the layer is relatively even.
-
While the white icing is still wet, take your black icing (in a piping bag or squeeze bottle) and pipe a small dot directly in the center of the white icing on each cookie. Then, starting just to the left of this central dot, pipe a continuous spiral line of black icing, working your way outwards towards the edge of the cookie. Don’t worry if it’s not perfectly even. Immediately after piping the spiral, grab a wooden toothpick. Starting from the central black dot, drag the toothpick outwards in a straight line towards the edge of the cookie, pulling the black icing into the white. Repeat this action, creating approximately 5-6 evenly spaced lines all around the cookie to form a distinctive spiderweb pattern.
-
Continue this decorating process with all the remaining cookies. Once all the cookies are decorated, allow them to set undisturbed until the royal icing is completely dry and firm, which usually takes about 1 hour. Once set, these spooky and delicious Peanut Butter Spiderweb Cookies are ready to be enjoyed or packed for gifting!
