Let’s get started and create some edible creepy crawlies!
Ingredients:
- ½ cup (113g) unsalted butter (1 stick, room temperature)
- ½ cup (107g) brown sugar
- ⅓ cup (66g) granulated sugar
- ¾ cup (201g) creamy peanut butter (not natural)
- 1 large egg
- 1 tsp vanilla extract
- 1 ½ cups (180g) all purpose flour
- 1 tsp baking soda
- ½ tsp baking powder
- ½ tsp salt
- Granulated sugar (for rolling the cookies)
- Mini Reese’s Peanut Butter Cups
- ½ cup (85g) semi-sweet chocolate chips (for melting)
- ½ tsp neutral oil (for melting)
- Candy eye balls.
Cookie Dough Preparation
The first step to creating our peanut butter spiders is to make a fantastic, chewy peanut butter cookie dough. In a large mixing bowl, cream together your softened unsalted butter, brown sugar, and granulated sugar. Using an electric mixer or a sturdy whisk, beat them until the mixture is light and fluffy. This process incorporates air into the dough, which helps create a tender cookie. Make sure your butter is truly at room temperature – it shouldn’t be melted, but soft enough to indent easily with your finger. Next, beat in the creamy peanut butter until everything is well combined and smooth. This is where the star flavor comes from, so don’t be shy! Now, add the large egg and vanilla extract. Mix these in until they are fully incorporated into the dough. A crucial tip here is to not overmix once the egg is added.
In a separate medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. Whisking these dry ingredients together ensures that the leavening agents and salt are evenly distributed throughout the flour, preventing pockets of saltiness or uneven rising in your cookies. Gradually add the dry ingredients to the wet ingredients, mixing on low speed or by hand just until the flour streaks disappear. Be careful not to overmix at this stage; overmixing can develop the gluten in the flour too much, resulting in tough cookies. The dough should be thick and slightly sticky.
Forming and Baking the Spider Bodies
Once your cookie dough is ready, it’s time to form our cookie bases. Scoop about 1 tablespoon of dough and roll it into a ball. For an extra touch of sweetness and a lovely finish, roll each dough ball in the granulated sugar you’ve set aside. This not only adds a delightful crunch but also helps prevent the cookies from spreading too much. Place the sugared dough balls about 2 inches apart on baking sheets lined with parchment paper. Parchment paper is your friend here, making cleanup a breeze and ensuring your cookies don’t stick.
Now comes the fun part where we create the spider’s body! Before baking, gently press a mini Reese’s Peanut Butter Cup into the center of each dough ball. Don’t push it all the way through, just enough so it’s firmly set into the dough. As the cookies bake, the Reese’s Cup will melt and become a gooey, delicious center, resembling the spider’s plump body. Bake in a preheated oven at 350°F (175°C) for 9-11 minutes, or until the edges are lightly golden brown and the centers appear slightly soft. They will continue to set as they cool. Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. This is important to prevent them from breaking.
Creating the Chocolate Legs and Features
While your cookies are cooling, it’s time to prepare for the spider’s creepy crawly legs. In a microwave-safe bowl, combine the semi-sweet chocolate chips and the neutral oil. Microwave in 30-second intervals, stirring well after each interval, until the chocolate is completely melted and smooth. The oil helps the chocolate melt evenly and achieve a smooth consistency, perfect for piping. You can also melt the chocolate using a double boiler method if you prefer.
Once the chocolate is melted and smooth, transfer it into a small piping bag or a zip-top bag with a tiny corner snipped off. You can also use a toothpick or a small spoon to draw the legs, but a piping bag gives you more control. Take your completely cooled peanut butter cookies. You’ll want to be precise with your spider legs! Pipe eight thin lines of melted chocolate radiating from the melted Reese’s Peanut Butter Cup “body” of each cookie. Aim for three legs on each side and two pointing upwards, creating the classic spider look. Work quickly as the melted chocolate can start to set.
Adding the Finishing Touches and Final Assembly
The final touch that brings our peanut butter spiders to life is, of course, their eyes! Before the chocolate legs have fully set, gently press two candy eye balls onto the melted chocolate “body” (the Reese’s Peanut Butter Cup) above the piped legs. If your chocolate has already set, you can add a tiny dot of melted chocolate to the back of the candy eyes to help them stick. This gives your spiders a fun, whimsical expression.
Once all the decorations are in place, allow the chocolate to set completely. You can speed this up by placing the cookies in the refrigerator for about 10-15 minutes. And there you have it – your very own batch of spooky and delicious Peanut Butter Spider Cookies! These are sure to be a delightful addition to any Halloween celebration or simply a fun treat to enjoy anytime. They store well in an airtight container at room temperature for up to 3-4 days, though I doubt they’ll last that long! Enjoy every creepy, crawly bite!

Frequently Asked Questions:
Can I make these cookies ahead of time?
Absolutely! You can bake the cookies and store them in an airtight container at room temperature for up to 3-4 days. You can even decorate them a day in advance.
What if I don’t have black licorice for the legs?
No problem! You can use pretzel sticks cut into smaller pieces, or even thin strips of black fondant or fruit leather if you have those on hand. Get creative with your spider legs!
Are these cookies very sweet?
The sweetness level is generally balanced, thanks to the savory peanut butter. You can adjust the sugar slightly if you prefer a less sweet cookie, but I find the current ratio to be just right.
