Ingredients Breakdown

This recipe yields 15–20 cookies depending on the size of your dough balls. Every component works together for flavor, texture, and presentation.

Dry Ingredients

• 1¾ cups all-purpose flour – Provides structure and chewiness.
• 1 tsp baking soda – Helps the cookies rise and gives them that soft, tender center.
• ¼ tsp salt – Balances the sweetness and enhances peanut butter flavor.

Wet Ingredients

• ½ cup unsalted butter, room temperature – Adds richness and soft texture.
• ½ cup light brown sugar – Brings depth and moisture.
• ½ cup granulated sugar – Creates the perfect crisp edge.
• ½ cup smooth peanut butter – The hero ingredient that gives these cookies their signature flavor.
• 1 egg – Binds the dough and adds tenderness.
• 2 tsp vanilla extract – Rounds out the flavor beautifully.
• 1 tbsp whole milk – Softens the dough and ensures even baking.

For Decoration

• 15–20 miniature Reese’s Peanut Butter Cups – The spider bodies; perfectly bite-sized and delicious.
• ¼ cup semi-sweet chocolate – Melted for the spider legs and to “glue” on the eyes.
• 30–40 candy eyes – Two per cookie for a cute, spooky finish.

Tools & Equipment Needed

You don’t need fancy equipment—just some baking essentials to make the process smooth and fun.

• 2 cookie sheets
• Parchment paper
• Mixing bowls (one medium, one large)
• Whisk
• Hand mixer or stand mixer with paddle attachment
• Spatula
• Measuring cups and spoons
• Plastic wrap (for chilling dough)
• Wire cooling rack
• Microwave-safe bowl (for melting chocolate)
• Piping bag or small zip-top bag (for the spider legs)

Step-by-Step Instructions

Follow these detailed steps to ensure perfect cookies every time.

Step 1: Prepare the Baking Sheets

Line two cookie sheets with parchment paper and set them aside. This prevents sticking and makes cleanup easy.

Step 2: Combine Dry Ingredients

In a medium-sized bowl, whisk together:

• 1¾ cups all-purpose flour
• 1 tsp baking soda
• ¼ tsp salt

Set this dry mixture aside while you prepare the wet ingredients.

Step 3: Cream the Butter and Sugars

In a large mixing bowl (or stand mixer fitted with the paddle attachment), cream together:

• ½ cup unsalted butter, room temperature
• ½ cup light brown sugar
• ½ cup granulated sugar

Beat on medium speed until light, creamy, and fluffy—about 2–3 minutes. Scrape down the sides of the bowl to ensure even mixing.

Step 4: Add the Peanut Butter

Add ½ cup smooth peanut butter to the creamed butter and sugar. Continue mixing until fully incorporated and the mixture looks pale and whipped. This step infuses the dough with that classic peanut butter flavor and texture.

Step 5: Mix in Egg, Vanilla, and Milk

Add:

• 1 egg
• 2 tsp vanilla extract
• 1 tbsp whole milk

Mix until the dough is smooth and uniform, scraping down the sides to make sure everything blends evenly.

Step 6: Add the Dry Ingredients

Slowly add the flour mixture to the wet ingredients. Mix on low speed just until combined. The dough should be soft but not sticky. Avoid overmixing—this keeps the cookies tender.

Step 7: Chill the Dough

Cover the dough bowl tightly with plastic wrap and refrigerate for at least 2 hours or overnight. Chilling is key—it solidifies the fats, enhances the peanut butter flavor, and prevents the cookies from spreading too much while baking.

Step 8: Preheat and Shape

Preheat your oven to 375°F (190°C).

Scoop the dough into 2 tablespoon-sized balls and place them on the prepared cookie sheets, spaced about 2 inches apart to allow for spreading.

Step 9: Bake

Bake the cookies for 10–12 minutes, or until golden brown around the edges. The centers will still look slightly soft—that’s perfect. They’ll continue to set as they cool.

Step 10: Add the Reese’s Cups

Once out of the oven, let the cookies rest on the baking sheet for 3–5 minutes.
Now, gently press a miniature Reese’s Peanut Butter Cup onto the center of each cookie.

Timing matters:

• If you press them too early, the Reese’s will melt and lose their shape.
• If you wait too long, they won’t adhere properly.

Allow the cookies to cool completely on a wire rack before decorating.

Step 11: Melt the Chocolate

Once the cookies have cooled and the Reese’s are set, melt ¼ cup semi-sweet chocolate in a microwave-safe bowl. Heat in 30-second intervals, stirring between each, until smooth and glossy.

Step 12: Decorate

Transfer the melted chocolate to a piping bag (or a small zip-top bag with the corner snipped off). Pipe eight spider legs extending from each Reese’s Cup—four on each side.

Use a small dab of melted chocolate to attach two candy eyes to the front of each “spider.”

Allow the chocolate to set completely before moving or serving.

Step 13: Enjoy!

Once set, your cookies are ready to enjoy! These adorable peanut butter spiders are spooky, sweet, and perfectly chewy.

Tips & Variations

• Chill the Dough Properly: Don’t skip the chilling time. It helps the cookies bake evenly and hold their shape.
• Perfect Timing for Reese’s: Wait a few minutes after baking before pressing the candies on top—this prevents melting.
• Even Legs: Use a fine piping tip for cleaner lines when drawing the legs.
• Peanut-Free Alternative: Substitute the peanut butter and Reese’s with sunflower seed butter and mini chocolate cups for a nut-free version.
• Festive Twist: Add a drizzle of orange-colored chocolate or edible glitter for a Halloween party upgrade.

Flavor Profile & Pairings

These cookies combine the best of peanut butter and chocolate in one festive bite.

• Taste: Sweet and nutty with a hint of saltiness, balanced by rich chocolate.
• Texture: Soft and chewy center, crisp edges, and a creamy Reese’s top.
• Aroma: Warm, buttery peanut butter scent with hints of vanilla.

They pair perfectly with a tall glass of milk, hot cocoa, or a warm cup of coffee during those cozy fall evenings.

Ingredient Spotlight

Peanut Butter

The heart of this recipe. Choose smooth, no-stir peanut butter for consistent texture. Natural peanut butter can separate and affect baking consistency.

Storage Tip: Keep tightly sealed at room temperature. Stir before measuring for even consistency.

Reese’s Peanut Butter Cups

Miniature Reese’s make the perfect “spider bodies.” Their shape, flavor, and color fit the theme beautifully.

Alternative: For nut allergies, use nut-free chocolate cups or small truffles.

Candy Eyes

These tiny sugar decorations instantly bring personality to your cookies. Available in most baking aisles or craft stores.

Pro Baking Tips

• Cream Butter Properly: Beat butter and sugars until fluffy for the perfect cookie texture.
• Don’t Overmix: Mix flour in gently to avoid dense cookies.
• Chill Is Key: Chilled dough keeps cookies from spreading too thin.
• Watch the Oven: Bake just until golden brown; overbaking leads to dryness.
• Decorate on Cool Cookies: Ensure Reese’s and chocolate set properly before adding eyes.
