Key Ingredients Overview

Understanding the key ingredients in Peanut Butter Spider Cookies is essential for making them successfully. Each component plays a crucial role in the texture, flavor, and overall design of the cookies.

Peanut Butter: The creamy peanut butter is the star ingredient, providing richness and a smooth texture to the cookies. It’s important to use regular peanut butter, not natural, as the consistency is crucial for proper mixing and baking.
Brown and Granulated Sugars: A combination of brown sugar and granulated sugar adds the perfect balance of sweetness and moisture. Brown sugar gives the cookies a slight chewiness, while granulated sugar contributes to a light, crisp edge.
Mini Reese’s Peanut Butter Cups: These candies are the focal point of the spider design. By freezing them before baking, they retain their shape when pressed into the hot cookies, serving as the “body” of the spider.
Semi-sweet Chocolate Chips: These are melted and used to pipe the spider legs, adding a rich, chocolatey element to the decoration. The chocolate also helps attach the candy eyeballs to the cookies.
Candy Eyeballs: The candy eyeballs are a fun finishing touch, turning the Reese’s Cup into a spooky spider. They’re easy to apply and bring the Halloween theme to life in each cookie.

Step-by-Step Recipe Guide

Preparing the Reese’s Cups

Freezing the mini Reese’s Peanut Butter Cups is a key step in ensuring they maintain their shape when pressed into the freshly baked cookies. The heat from the cookies can cause the candy to soften or melt, so freezing the Reese’s Cups beforehand helps them stay firm and stable. Aim to freeze them for at least 30 minutes before starting the recipe.

When handling the frozen Reese’s Cups, it’s important to work quickly and carefully. Gently unwrap them, avoiding excess handling that could warm them up prematurely. If they start to soften, you can return them to the freezer while you continue preparing the dough. Freezing them not only prevents melting but also ensures that the candies will hold their form, allowing you to easily press them into the hot cookies right out of the oven.

Making the Cookie Dough

Start by creaming the butter and sugars together. In a large mixing bowl, use an electric mixer on medium speed to beat together one stick of room-temperature unsalted butter, ½ cup of brown sugar, and ⅓ cup of granulated sugar. Creaming these ingredients for about one minute helps create a light and fluffy texture, which is crucial for soft, well-structured cookies.

Next, add the peanut butter. Use ¾ cup of creamy peanut butter, and make sure it’s not natural peanut butter, which can separate and affect the texture of the dough. Beat the peanut butter into the creamed butter and sugar mixture until smooth.

Now, add one large egg and 1 teaspoon of vanilla extract, continuing to mix until everything is well incorporated. The egg binds the ingredients together, while the vanilla adds a subtle depth of flavor.

In a separate bowl, whisk together the dry ingredients: 1 ½ cups of all-purpose flour, 1 teaspoon of baking soda, ½ teaspoon of baking powder, and ½ teaspoon of salt. Slowly incorporate the dry ingredients into the wet mixture, mixing on low speed. Be careful not to overmix, as this can lead to tough or dense cookies. Stop mixing as soon as the flour disappears into the dough. Overmixing is a common mistake and can make cookies less tender.

Shaping and Rolling the Cookies

Once the dough is ready, use a tablespoon or cookie scoop to portion out even balls of dough. Each ball should be roughly the size of a tablespoon. Roll the dough between your hands until you form smooth, round balls.

Next, roll each dough ball in granulated sugar. This coating not only adds a slight crunch to the exterior of the cookies but also helps them brown evenly as they bake. Once coated, place the dough balls on a baking sheet lined with parchment paper or a silicone baking mat, spacing them 2-3 inches apart. This ensures the cookies have enough room to spread while baking, preventing them from merging.

Baking the Cookies

Preheat your oven to 350ºF (175ºC) before baking. Bake the cookies for 8-11 minutes, keeping a close eye on them. You’ll know they are ready when the edges are lightly golden and have begun to crack, while the centers are still soft but set. Avoid overbaking, as this will result in dry cookies instead of soft, chewy ones.

The visual cues are more important than the time, as every oven bakes differently. Once the edges appear done, remove the cookies from the oven even if the centers seem slightly underbaked. The cookies will continue to firm up as they cool on the baking sheet.

Pressing the Reese’s Cups

Immediately after removing the cookies from the oven, take your frozen Reese’s Peanut Butter Cups and gently press one into the center of each cookie while they are still hot. Press down just enough so that the cup is nestled securely but not too far to avoid sinking it completely into the cookie.

It’s important to act quickly while the cookies are hot and soft enough to accept the Reese’s Cups. The heat will slightly melt the bottom of the Reese’s Cups, helping them stick to the cookie without losing their shape.

Once all the cookies have their Reese’s Cups pressed in, let the cookies cool on the baking sheet for about 15-20 minutes. This cooling period allows the candy to firm back up and helps the cookies maintain their structure. Attempting to move the cookies too early can cause the Reese’s Cups to sink or lose their shape, which is why patience during this step is key to perfect-looking spider cookies.

Melting the Chocolate

To create the spider legs, melt ½ cup of semi-sweet chocolate chips. Place the chocolate chips in a microwave-safe bowl and microwave them on 50% power in 1-minute intervals, stirring between each interval until the chocolate is fully melted. This method ensures that the chocolate melts smoothly without burning.

Once the chocolate is melted, transfer it into a piping bag or a small sandwich bag. If using a sandwich bag, snip off a tiny corner to allow for precise piping. This step is important for controlling the flow of chocolate, making it easier to pipe the spider legs with accuracy and precision.

Make sure the chocolate is warm but not too hot, as piping with overly hot chocolate can result in runny lines that won’t hold their shape.

Decorating the Spider Cookies

With your melted chocolate ready, it’s time to add the spider legs to each Reese’s Cup. Using the piping bag or sandwich bag, pipe four legs on each side of the Reese’s Cup to mimic a spider’s legs. Start at the base of the Reese’s Cup and pipe outward, curving the legs slightly to make them look more natural. Repeat this process for all the cookies.

Once the legs are piped, it’s time to add the candy eyeballs. Dab a small dot of melted chocolate onto the back of each candy eyeball and place two eyeballs on top of each Reese’s Cup, near the center. The melted chocolate acts as glue to secure the eyes in place.

For an extra touch of creativity, you can experiment with different leg lengths or adjust the angle of the legs to give each spider a unique look. You can also use different colors of melted chocolate if you want to add some variety or a more playful design to your cookies. Feel free to get creative with how your spiders look—whether they are cute and friendly or spooky and eerie.

Letting the Cookies Set

After decorating, allow the cookies to set fully before transferring them to a serving platter. This can take about 30 minutes at room temperature or less if you place the cookies in the refrigerator for a quicker set time. It’s important to let the chocolate harden so the legs and eyeballs stay in place and don’t smear or move when you handle the cookies.

Once the cookies have set, store them in an airtight container at room temperature. They will stay fresh for several days and remain an eye-catching treat for any Halloween gathering.

Tips and Variations

Cookie Baking Tips and Troubleshooting

When making Peanut Butter Spider Cookies, a few common mistakes can impact the final result, but with the right tips, they are easy to avoid. One issue is dough that becomes too dry. This can happen if you add too much flour or overmix the dough. Be sure to measure your flour correctly (scoop and level) and stop mixing as soon as the flour is fully incorporated.

Another common problem is cookies spreading too much during baking. This can be caused by using overly warm dough. To prevent spreading, you can chill the dough for 15-20 minutes before baking. If your Reese’s Cups melt too much when pressed into the cookies, make sure they are fully frozen before use and press them into the cookies gently to prevent sinking.

Finally, oven temperatures can vary, so it’s important to adjust baking time based on your oven’s performance. Keep an eye on the visual cues, such as edges turning golden and the center remaining soft but set, to know when the cookies are done.

Fun Variations

While the classic peanut butter cookie base is delicious, you can switch things up by using different cookie doughs. For a chocolate twist, try using chocolate cookie dough as a base while keeping the Reese’s Cups as the spider body. Alternatively, oatmeal cookies can add a chewy texture that complements the smooth peanut butter cup.

For more creative Halloween decorations, you can substitute the candy eyeballs with other small candies like mini M&M’s or use colored chocolate melts to pipe legs in fun Halloween colors like orange or purple. You can also dip the Reese’s Cups in white chocolate before decorating to make ghost spiders.

To make the cookies gluten-free, simply swap the all-purpose flour for a 1:1 gluten-free baking flour mix. For vegan cookies, you can use a vegan butter substitute, flax egg (1 tablespoon flaxseed meal mixed with 3 tablespoons water), and dairy-free chocolate alternatives. Vegan peanut butter cups, like Justin’s or a homemade version, can also be used to complete the recipe.

FAQs

Can I use natural peanut butter in the cookies?
It’s best to avoid using natural peanut butter in this recipe. Natural peanut butter tends to separate, leading to an inconsistent texture in the cookie dough. The added oils in natural peanut butter can make the cookies spread too much or turn out greasy. Creamy, processed peanut butter (like Jif or Skippy) is formulated to maintain a stable consistency, making it ideal for baking. If you need a healthier alternative, look for a no-stir variety that mimics the texture of processed peanut butter.

How do I stop the Reese’s Cups from melting too much?
To prevent the Reese’s Peanut Butter Cups from melting excessively, it’s crucial to freeze them before pressing them into the cookies. Aim to freeze them for at least 30 minutes. Additionally, work quickly when pressing them into the hot cookies immediately after they come out of the oven. This helps the cups maintain their shape, preventing them from sinking too deeply or becoming overly soft.

Can I use different types of chocolate for the spider legs?
Yes! You can experiment with various types of chocolate depending on your preference. Dark chocolate, milk chocolate, or even white chocolate can all work well for the spider legs. Just be mindful of the texture: dark and semi-sweet chocolates melt smoothly, while milk and white chocolates are sweeter and might melt slightly thicker, which can affect piping precision.

How can I store these cookies?
Store the Peanut Butter Spider Cookies in an airtight container at room temperature. They will stay fresh for up to 4-5 days. To ensure the spider decorations stay intact, avoid stacking the cookies or place a sheet of parchment paper between layers.

Can I make these cookies ahead of time?
Yes, you can prepare the cookies in advance. You can bake the cookies and freeze them (without decorations) for up to 2 months. When you’re ready to serve, thaw them at room temperature and add the Reese’s Cups, chocolate legs, and candy eyeballs fresh to preserve their look.
