Ingredients List
Gather these items to craft your spooky Halloween treats:
- 1/2 cup creamy peanut butter – choose smooth for that velvety texture in every bite.
- 1/2 cup unsalted butter, softened – ensures a tender crumb without overpowering saltiness.
- 1/2 cup granulated sugar – adds sweetness and helps with browning.
- 1/2 cup brown sugar, packed – brings moisture and a caramel-like depth.
- 1 large egg, at room temperature – binds everything together for fluffy results.
- 1 teaspoon vanilla extract – enhances the warm, inviting aroma.
- 1 1/4 cups all-purpose flour – the foundation for structure.
- 1/2 teaspoon baking soda – gives a slight lift for chewiness.
- 1/4 teaspoon salt – balances flavors.
- 24 mini Reese’s peanut butter cups, unwrapped – forms the spider bodies with their rich chocolate-peanut fusion.
- 1/2 cup semisweet chocolate chips, melted – for piping realistic spider legs.
- 48 small candy eyes – adds the cute yet eerie stare that makes these Halloween desserts pop.
Step-by-Step Instructions
Start by preheating your oven to 350°F and lining two baking sheets with parchment paper for easy cleanup. In a large bowl, cream together the peanut butter, butter, granulated sugar, and brown sugar until light and fluffy, about 2 minutes – this step incorporates air for a soft texture. Beat in the egg and vanilla extract until fully combined, scraping down the sides as needed.
In a separate bowl, whisk the flour, baking soda, and salt, then gradually mix into the wet ingredients until just blended – avoid overmixing to keep them tender. Roll the dough into 1-inch balls and place them 2 inches apart on the sheets. Bake for 8-10 minutes until edges are golden but centers remain soft.
Remove from the oven and immediately press a mini Reese’s cup into the center of each warm cookie – the heat melts it slightly for perfect adhesion. Let cool for 5 minutes on the sheet. Melt the chocolate chips in the microwave in 30-second bursts, stirring until smooth, then transfer to a piping bag or zip-top bag with a tiny corner snipped off.
Pipe 8 legs extending from each Reese’s cup to mimic spider limbs. Gently press two candy eyes onto each chocolate body while the piped chocolate is still wet. Allow to set for 10 minutes before serving these irresistible Halloween spider cookies.
Tips for Success
For the best chewy texture, measure flour by spooning it into the cup and leveling off to prevent dense cookies. Pull them from the oven when slightly underdone – they firm up as they cool. If the dough sticks while rolling, chill it for 10 minutes. Test melt the chocolate in short intervals to avoid seizing.
Serving Suggestions
Present these peanut butter spider cookies on a black platter sprinkled with edible glitter for a haunted vibe, or nestle them in cupcake liners for individual treats. Pair with hot apple cider or pumpkin spice lattes to complement the nutty sweetness.
For extra flair, arrange them around a fog machine or with dry ice for a misty, eerie display at your Halloween bash.
Storage Tips
Keep these Halloween desserts in an airtight container at room temperature for up to 3 days to maintain chewiness. Refrigerate for a week if you prefer them firmer, though bring to room temp before eating. Freeze baked cookies without decorations in a zip-top bag for up to 2 months; thaw and add spiders fresh.
FAQs
Can I use crunchy peanut butter instead?
Yes, crunchy adds extra texture and works just as well for a nuttier bite.
What if I’m allergic to peanuts?
Swap for sunflower seed butter and use chocolate truffles instead of Reese’s for a safe alternative.
My chocolate seized – how to fix?
Stir in a teaspoon of vegetable oil to smooth it out next time.
Can I make the dough ahead?
Absolutely, refrigerate it up to 48 hours or freeze for a month before baking.
Why did my cookies spread too much?
Chill the dough first or use colder butter to control spreading.
