Step-by-Step: How to Make Halloween Peanut Butter Spider Cookies

Step 1 – Mix the dough
In a large bowl, cream together butter, peanut butter, and both sugars. Beat until fluffy. Add the egg and vanilla, mix again. In a separate bowl, whisk flour, baking soda, and salt. Slowly add dry ingredients to wet, mixing until just combined.

Step 2 – Bake the cookies
Preheat oven to 350°F (175°C). Line a baking sheet with parchment. Scoop dough into tablespoon-sized balls, flatten slightly. Bake for 8–10 minutes until lightly golden.

Step 3 – Add the peanut butter cups
Right after baking, press one frozen mini peanut butter cup into the center of each cookie. Transfer to a cooling rack and allow to cool completely.

Step 4 – Decorate the spider cookies
Melt chocolate and transfer to a piping bag. Pipe four legs on each side of the peanut butter cup to mimic a spider. Use a dab of chocolate to secure two candy eyes on top.

In under 30 minutes, you’ve got playful, eye-catching Halloween Peanut Butter Spider Cookies ready to share.

Creative Ways to Decorate Spider Cookies

The best part of making Halloween Peanut Butter Spider Cookies is the decorating. For a clean look, stick with the classic legs and eyes. But if you’re feeling adventurous, go bold:

• Use colorful candy melts for neon spiders
• Add edible glitter or Halloween sprinkles
• Create “fangs” using mini chocolate chips
• Pipe red gel icing for spooky blood effects

Arrange alongside cherry iced tea or spooky cupcakes for a showstopping Halloween treat table.

Fun Variations on Halloween Peanut Butter Spider Cookies

The base cookie is easy to tweak. Try:

• A chocolate cookie base instead of peanut butter
• Substituting caramel-filled chocolates for peanut butter cups
• Swapping in candy eyeballs of different colors

• Turning them into Halloween Peanut Butter Eyeballs by adding red gel “veins”

You can also use the same dough to form mini “monster bites” or peanut butter bats.

Mistakes to Avoid with Halloween Peanut Butter Spider Cookies
