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
1. Creaming the Butter and Sugars: In a large mixing bowl, start by creaming together your softened unsalted butter, brown sugar, and granulated sugar. For best results, ensure your butter is truly at room temperature – not melted, but soft enough to be easily indented with your finger. This will help it incorporate smoothly with the sugars. Beat these together with an electric mixer (or a sturdy whisk and some elbow grease) on medium speed until the mixture is light, fluffy, and pale in color. This process incorporates air, which is crucial for creating a tender cookie texture. Scrape down the sides of the bowl periodically to make sure everything is well combined.
2. Adding Wet Ingredients: Next, beat in the creamy peanut butter until it’s fully incorporated into the butter and sugar mixture. Make sure to use a creamy peanut butter that isn’t the natural, oily kind, as this can affect the texture and spread of the cookies. Then, crack in your large egg and add the vanilla extract. Beat again until everything is well combined and the mixture is smooth. The dough might look a little streaky at this point, and that’s perfectly fine.
3. Combining Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. Whisking the 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.
4. Forming the Dough: Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix the dough once the flour is added, as this can lead to tough cookies. Stop mixing as soon as you no longer see streaks of dry flour. The dough will be thick and somewhat sticky.
Shaping and Baking the Spiders
5. Chilling and Rolling: Cover the bowl with plastic wrap and refrigerate the dough for at least 30 minutes. Chilling the dough is a very important step. It allows the fats to firm up, which prevents the cookies from spreading too much during baking, resulting in thicker, chewier cookies. It also makes the dough easier to handle. Once chilled, scoop rounded tablespoons of dough and roll them into balls. Then, roll each ball in the additional granulated sugar set aside. This sugar coating not only adds a lovely sparkle and crunch but also helps create that classic cookie texture.
6. Preparing for the Reese’s Body: Place the sugar-coated dough balls about 2 inches apart on a baking sheet lined with parchment paper. Now, take your Mini Reese’s Peanut Butter Cups. Gently press one Mini Reese’s Peanut Butter Cup into the top of each cookie dough ball. You want the cup to be pressed in about halfway, so it sits snugly in the dough. This will become the spider’s body.
7. Baking to Perfection: Preheat your oven to 350°F (175°C). Bake the cookies for 9-12 minutes, or until the edges are lightly golden brown and the centers look slightly underbaked. They will continue to cook slightly as they cool on the baking sheet. Allow the cookies to cool on the baking sheet for 5-10 minutes before carefully transferring them to a wire rack to cool completely. It’s important to let them cool on the baking sheet for a bit to firm up, as they will be quite soft when they first come out of the oven.
Spider Assembly: The Fun Part!
8. Melting the Chocolate: While the cookies are cooling, it’s time to prepare the chocolate for our spider legs. Place the semi-sweet chocolate chips and the neutral oil in a microwave-safe bowl. Microwave in 30-second intervals, stirring well after each interval, until the chocolate is completely smooth and melted. Be careful not to overheat the chocolate. The neutral oil helps to create a smoother, more fluid consistency, perfect for piping.
9. Creating the Spider Legs: Once the cookies are completely cool, and the chocolate is melted and slightly cooled (you don’t want it piping hot), spoon the melted chocolate into a small piping bag fitted with a very small round tip, or a zip-top bag with a tiny corner snipped off. Alternatively, you can use a toothpick for this step, though it will be more time-consuming. Carefully pipe eight “legs” emanating from the sides of the Reese’s Peanut Butter Cup body onto the cooled cookie. You can make them thin or slightly thicker, whatever your spider-design preference dictates!
10. Adding the Eyes: Finally, it’s time for the spider’s eyes! Gently press two candy eye balls onto the front of the Reese’s Peanut Butter Cup body, just above the legs, using a tiny dot of the melted chocolate as “glue” if needed to help them adhere. Let the chocolate set completely, which will happen relatively quickly at room temperature, or you can speed it up by placing the cookies in the refrigerator for a few minutes.
And there you have it – your very own batch of creepy, crawly, and delicious Peanut Butter Spider Cookies! Enjoy their delightful peanut butter flavor and the fun, festive presentation. They’re sure to be a hit!
