How to Make Peanut Butter Spider Cookies?
Step 1: Prepare the Reese’s Cups
Start by unwrapping about 24 mini Reese’s and placing them in the freezer. ❄️ Freezing helps them maintain their shape when you press them into the hot cookies later.
Step 2: Make the Dough
Combine the butter, brown sugar, and granulated sugar in a mixing bowl. Beat with an electric mixer until the mixture is light and fluffy, about 1 minute. Then, add the peanut butter, egg, and vanilla extract, mixing until smooth.
Step 3: Mix in Dry Ingredients
Gradually add the flour, baking soda, baking powder, and salt to the bowl. Mix on low speed or with a spatula until just combined. Be careful not to overmix!
Step 4: Form and Bake
Scoop tablespoon-sized balls of dough, roll them between your palms, and then roll them in sugar. Place them on a lined baking sheet, about 2 inches apart, and bake at 350°F for 8–11 minutes. 🍪 The edges should crack slightly for that perfect cookie finish.
Step 5: Add the Reese’s
While the cookies are still warm, gently press a frozen Reese’s into the center of each one. Allow the cookies to cool on the baking sheet for about 15-20 minutes to set.
Step 6: Create the Spider Legs
Melt the chocolate chips in a microwave-safe bowl, stirring every 30 seconds until fully melted. 🕷️ Transfer the melted chocolate to a squeeze bottle or plastic bag with a small corner cut. Pipe four legs on each side of the Reese’s cup.
Step 7: Add the Candy Eyes
Use a small dab of melted chocolate to attach two candy eyeballs onto each Reese’s cup. 👀 Let everything set completely before serving or transferring to a container.

Tips for Making the Recipe
- Equal Cookie Sizes
Using a cookie scoop ensures your cookies bake evenly and look uniform. - Freeze Reese’s Cups
Freezing prevents the Reese’s from melting and losing their shape. - Don’t Overbake
Cookies should look just set and have slightly cracked edges. Remember, they’ll continue baking on the sheet after being removed from the oven. - Work Quickly
Attach the candy eyes while the chocolate legs are still warm and tacky for better adhesion.
How to Serve Peanut Butter Spider Cookies?
These cookies are a showstopper on any dessert table! Arrange them neatly on a platter or add them to a Halloween dessert board with cupcakes, candy corn, and ghost-shaped brownies. For an extra dash of frightful fun, serve them on an orange or black napkin with a drizzle of edible glitter dusted across the top.
Make Ahead and Storage
- Refrigerating: Store the cookies in an airtight container at room temperature for up to 3 days. If stacked, use wax paper between layers to prevent smudging.
- Freezing Dough: Prepare the cookie dough balls and freeze them uncoated (no sugar rolling yet). Store in a freezer-safe bag and bake directly from frozen, adding a minute to the bake time.
- Freezing Baked Cookies: Fully cooled cookies can also be frozen. Simply place them in an airtight container, stacking with layers of wax paper, and freeze for up to 3 months. Defrost at room temperature before serving.
