Soft and chewy peanut butter spider cookies are the ultimate Halloween treat that combines fun, flavor, and a bit of spooky charm. With a creamy peanut butter base, a chocolatey Reese’s center, and playful candy eyes, these cookies are perfect for parties, trick-or-treat boxes, or simply bringing some seasonal joy to your table.
I first baked these for a Halloween get-together with friends, and they disappeared faster than any other dessert on the table. They’ve been a seasonal tradition ever since.
Ingredients
- Unsalted butter: at room temperature gives a rich base for the cookies
- Brown sugar: adds depth with a light molasses note
- Granulated sugar: balances the sweetness and helps with rolling the dough
- Creamy peanut butter: skip natural versions for best texture
- Large egg: binds the dough together for soft cookies
- Vanilla extract: deepens the cookie flavor
- All purpose flour: the structure of the dough
- Baking soda and baking powder: ensure proper rise and softness
- Salt: balances the sweetness and enhances peanut butter
- Granulated sugar for rolling: gives a light sparkle and crisp edge
- Mini Reese’s Peanut Butter Cups: the chocolatey spider bodies
- Semi sweet chocolate chips: melted to form the spider legs
- Candy eyeballs: add the playful finishing touch
Step by Step Instructions
- Chill the Reese’s:
- Unwrap 24 mini peanut butter cups and place them in the freezer while you prepare the dough. This keeps them firm when placed onto the hot cookies.
- Beat the Butter and Sugars:
- Using a mixer beat butter brown sugar and granulated sugar together until creamy and fluffy. This step helps the cookies turn out light rather than dense.
- Add Peanut Butter Egg and Vanilla:
- Blend in the peanut butter followed by the egg and vanilla until the mixture is smooth and uniform.
- Mix Dry Ingredients:
- In a separate bowl combine flour baking soda baking powder and salt then add gradually to the wet mixture until just combined. Do not overmix or the cookies can turn tough.
- Form and Bake:
- Scoop tablespoon sized portions roll into smooth balls and coat lightly in granulated sugar. Arrange on a lined baking sheet and bake at 350F for 8 to 11 minutes until just set with slight cracks on the edges.
- Add Reese’s Center:
- Press one frozen mini Reese’s gently into the center of each cookie while still warm. Let them rest on the baking sheet for at least 15 minutes so they firm up.
- Create Spider Legs:
- Melt chocolate chips in short bursts in the microwave stirring until smooth. Transfer to a piping bag or squeeze bottle and draw four legs on each side of the Reese’s.
- Attach Candy Eyes:
- Use a tiny dab of melted chocolate to stick candy eyeballs onto each Reese’s. Allow to set completely before serving or storing.

My favorite part is watching kids see the cookies for the first time Their excitement makes the little extra step of piping chocolate legs totally worth it
Storage Tips
Keep cookies in an airtight container at room temperature for up to three days. If stacking place parchment between layers to prevent smudging the chocolate. For longer storage freeze fully cooled cookies in a sealed container for up to three months.
Ingredient Substitutions
