We’re going to walk through each step together, ensuring you have all the information you need to create a batch of these memorable treats.
Ingredients:
- ½ cup (113g) unsalted butter (1 stick, room temperature)
- ½ cup (107g) brown sugar
- â…“ 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.
Instructions:
1. Cream the Butter and Sugars: In a large mixing bowl, add your softened unsalted butter, brown sugar, and granulated sugar. Using an electric mixer (or a sturdy whisk and some elbow grease), cream these ingredients together until the mixture is light, fluffy, and pale in color. This process incorporates air into the dough, which is crucial for a tender cookie texture. You want to see no visible lumps of butter or sugar; it should be a smooth, cohesive mass. Make sure your butter is truly at room temperature – too cold and it won’t cream properly, too warm and it will be greasy.
2. Incorporate Peanut Butter, Egg, and Vanilla: To the creamed butter and sugar mixture, add your creamy peanut butter. Again, mix on medium speed until well combined and smooth. The peanut butter helps to bind the dough and contributes significantly to the flavor. Next, crack in your large egg and add the vanilla extract. Mix on low speed until everything is just incorporated. Be careful not to overmix at this stage, as it can lead to tougher cookies. Scrape down the sides of the bowl occasionally to ensure all ingredients are evenly distributed.
3. Combine Dry Ingredients and Mix into Dough: In a separate medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. Whisking ensures that the leavening agents (baking soda and baking powder) and salt are evenly distributed throughout the flour, which is essential for consistent cookie rise and flavor. Gradually add this dry ingredient mixture to the wet ingredients in the large mixing bowl. Mix on low speed until just combined. The dough will be thick and may seem a bit stiff, which is exactly what we want. Avoid overmixing; stop as soon as you no longer see streaks of flour.
4. Shape and Bake the Cookies: Preheat your oven to 375°F (190°C). Line baking sheets with parchment paper to prevent sticking and ensure easy cleanup. Take about 1-2 tablespoons of dough for each cookie and roll it into a ball. Place the dough balls onto the prepared baking sheets, leaving about 2 inches of space between each cookie, as they will spread during baking. For the spider effect, we’re going to press a Mini Reese’s Peanut Butter Cup into the center of each cookie dough ball while it’s still raw. This will bake into the cookie, forming the spider’s body. You can gently press it down so it’s nestled into the dough. If you like a bit of sparkle, you can roll the dough balls in granulated sugar before pressing in the Reese’s cup. Bake for 9-11 minutes, or until the edges are lightly golden brown and the centers are still slightly soft. They will continue to set up as they cool on the baking sheet.
5. Create the Spider Legs and Eyes: While the cookies are cooling on the baking sheets for about 5 minutes, it’s time to give them their spider-like features. In a small 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 to make the chocolate smoother and easier to pipe. You can also use a double boiler for this. Transfer the melted chocolate to a piping bag fitted with a small round tip, or use a zip-top bag with a tiny corner snipped off. Carefully pipe eight “legs” extending from the sides of the Reese’s Peanut Butter Cup “body.” You can do thin lines or zig-zag patterns to mimic spider legs. Immediately after piping the legs, place two candy eyeballs onto the top of the Reese’s Peanut Butter Cup “body” before the chocolate sets. If the chocolate has started to harden, you can dab a tiny bit of melted chocolate to help the eyes stick. Let the cookies cool completely on a wire rack before handling or stacking.
These Peanut Butter Spider Cookies are not just a treat for your taste buds; they are a work of edible art. The combination of the rich peanut butter cookie, the sweet chocolate and peanut butter of the Reese’s cup, and the fun, festive decoration makes them an absolute winner. Enjoy the process, and get ready to hear delighted gasps when you reveal your spooky spider creations!

Frequently Asked Questions:
Can I make these cookies ahead of time?
Absolutely! These cookies store wonderfully in an airtight container at room temperature for up to 3-4 days. They might even taste better after a day as the flavors meld together.
What kind of peanut butter should I use?
You can use either creamy or crunchy peanut butter. Creamy will give you a smoother cookie texture, while crunchy will add a bit more chew and peanutty bits. Just ensure it’s regular, not natural peanut butter, as the oil separation can affect the cookie’s consistency.
How do I store the decorated cookies so the candy doesn’t fall off?
Once the cookies have cooled completely, store them in a single layer in an airtight container. If stacking, place parchment paper between layers to prevent the candy decorations from sticking to the cookies above.
