I’m a firm believer that baking should be fun and approachable, and these cookies definitely fit the bill. Plus, with Halloween being a major trending topic right now, there’s no better time to embrace the season and get creative in the kitchen. Let’s make some memories (and some seriously tasty cookies)!
Ingredients for Spider Cookies
- 1 cup (2 sticks) unsalted butter, softened: The fat in butter is crucial for creating a tender, melt-in-your-mouth cookie. Make sure it’s properly softened, not melted, to ensure even mixing. If you’re dairy-free, a good quality vegan butter alternative will work. The softening point is crucial, if it is too soft, the cookie will spread too much.
- 1 cup granulated sugar: White sugar contributes to the cookie’s crisp edges and overall sweetness.
- 1 cup packed light brown sugar: Brown sugar adds moisture and a chewy texture, along with a hint of molasses flavor that complements the peanut butter. Make sure it’s packed tightly when measuring for accurate results.
- 2 large eggs: Eggs bind the ingredients together and contribute to the cookie’s structure. Use large eggs for consistency in baking.
- 1 teaspoon vanilla extract: Vanilla extract enhances the other flavors in the cookie. Use pure vanilla extract for the best taste.
- 1 cup creamy peanut butter: This is the star of the show! Opt for a creamy peanut butter (not natural, unless you whisk it well) for a smooth cookie texture.
- 2 ½ cups all-purpose flour: Flour provides the structure for the cookies. Measure it accurately using the spoon and level method to avoid dry cookies.
- 1 teaspoon baking soda: Baking soda helps the cookies rise and creates a light, airy texture.
- ½ teaspoon salt: Salt enhances the sweetness and balances the flavors.
For the Spider Decoration:
- Pretzel sticks: These form the spider’s legs. Snap them in half or thirds for a more manageable size.
- Candy eyes: These are essential for creating the spider’s cute, yet spooky, look.
- Chocolate frosting or melted chocolate: This acts as the “glue” to attach the eyes and legs and to create any web details. A simple chocolate ganache also works really well.
Expert Tips for Perfect Spider Cookies
After countless batches of these creepy crawlies, I’ve learned a few tricks to guarantee cookie success:
- Chill the dough: This is KEY! Chilling the dough for at least 30 minutes (or even overnight) prevents the cookies from spreading too thin during baking and allows the flavors to meld together.
- Don’t overbake: Overbaked peanut butter cookies tend to be dry and crumbly. Bake until the edges are set and the centers are still slightly soft. They’ll continue to firm up as they cool.
- Get creative with decorations: While pretzel sticks and candy eyes are classic, feel free to experiment with different candies, sprinkles, or even colored frosting to personalize your spiders.
- Use parchment paper: Line your baking sheets with parchment paper for easy cleanup and to prevent the cookies from sticking.
- Rolling the dough in sugar before baking: Roll the peanut butter cookie dough balls in granulated sugar before baking for a sweet, sparkly crust.
Storage & Substitutions
Storage:
- Store baked Halloween Peanut Butter Spider Cookies in an airtight container at room temperature for up to 5 days. The cookies are usually best when enjoyed within the first 2-3 days, as they tend to soften over time due to moisture.
- For longer storage, you can freeze the baked cookies. Place them in a single layer on a baking sheet and freeze until solid. Then, transfer them to a freezer-safe container or bag. They can be frozen for up to 2-3 months. Thaw at room temperature before serving.
Substitutions:
- Nut-Free Option: Use sunflower seed butter (sunbutter) in place of peanut butter.
- Gluten-Free Option: Substitute all-purpose flour with a gluten-free all-purpose blend, ensuring it contains xanthan gum for binding.
- Vegan Option: Use vegan butter, a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons of water), and dairy-free chocolate for decorating.
- Sugar Alternatives: Coconut sugar can be used as a 1:1 replacement for granulated sugar. You can also use honey or maple syrup, but be aware that these may slightly alter the texture and flavor of the cookies.
FAQ About Peanut Butter Spider Cookies
Can I use natural peanut butter?
While you can use natural peanut butter, it often results in a drier, more crumbly cookie. If you do opt for natural peanut butter, make sure to stir it very well before measuring and perhaps add a tablespoon or two of extra moisture (milk or water) to the dough.
How do I prevent the cookies from spreading too much?
Chilling the dough is the most important step to prevent excessive spreading. Also, make sure your butter isn’t too soft (it should be pliable, not melted). You can also add 2 tbsp of flour to prevent spreading.
Can I freeze the cookie dough?
Yes! Scoop the cookie dough into balls, place them on a baking sheet, and freeze until solid. Then, transfer the frozen dough balls to a freezer-safe bag. When ready to bake, simply bake from frozen, adding a few extra minutes to the baking time.
What can I use if I don’t have pretzel sticks?
Licorice strings or even chocolate-covered pretzels can be used as alternatives for the spider’s legs. Get creative and use what you have on hand!
My cookies are too dry. What did I do wrong?
Over-measuring the flour is a common culprit for dry cookies. Make sure to use the spoon and level method when measuring flour. Also, avoid overbaking the cookies.
Can I make these ahead of time?
Absolutely! These cookies can be baked a day or two in advance. You can also prepare the dough and store it in the refrigerator for up to 3 days before baking.
