Creepily Delicious Peanut Butter Spider Cookies! 🕷️🍪 Soft, chewy, and just the right amount of spooky—perfect for Halloween treats!

  • Total Time: 28 minutes

Ingredients

Scale

For the Cookies:

  • 1. Prepare the Dough
    • Preheat your oven to 375°F (190°C) and line two baking sheets with parchment paper.
    • In a medium mixing bowl, combine the flour, baking soda, and baking powder. Set this dry mixture aside.
    • In a separate bowl, cream the softened butter, granulated sugar, and brown sugar until smooth.
    • Add the peanut butter, egg, and vanilla extract to the creamed mixture, and blend until fully combined.
    • Slowly incorporate the dry ingredients, mixing until a dough forms.

    2. Shape the Cookies

    • Using a 2-tablespoon scoop, scoop dough into small balls.
    • Roll each dough ball in granulated sugar for a delicate crunch on the outside.
    • Place the dough balls on your prepared baking sheets, leaving a bit of space between them.

    3. Bake the Cookies

    • Bake for 8–10 minutes, or until the cookies are just starting to turn golden around the edges.
    • Remove from the oven and let the cookies sit for a couple of minutes.

    4. Decorate with the Spiders

    • While the cookies are baking, sort out your Whoppers into 22 large and 22 small balls (one for each spider’s head and body).
    • Immediately after removing the cookies from the oven, press a large and a small Whopper into the center of each warm cookie to form the spider’s body and head.
    • Let the cookies cool for a few minutes before moving on to the chocolate decorations.

    5. Add the Spider Legs

    • Melt the semi-sweet chocolate chips in a microwave-safe bowl. Heat in 30-second increments, stirring between each, until smooth. Alternatively, you can use a double boiler.
    • Pour the melted chocolate into a piping bag or a plastic bag with a small snip at the corner.
    • Pipe eight legs on each spider by creating small “V” shapes from the center of each Whopper (four on each side).

    6. Add the Eyes

    • Using white cake decorating gel, add two small dots on the spider’s head for eyes.
    • Place a black nonpareil sprinkle or a dot of chocolate in the center of each white dot to complete the look.

    1 ½ cups all-purpose flour: Adds structure and softness to the cookies.

  • ½ tsp baking soda & ½ tsp baking powder: These leavening agents ensure the cookies have a slight rise and remain soft.
  • ½ cup salted butter, softened: Provides a rich, creamy base; use salted for best flavor balance, but if using unsalted, add a pinch of salt.
  • ½ cup granulated sugar & ½ cup brown sugar: A combination that gives both sweetness and a slightly chewy texture, with brown sugar adding a hint of molasses.
  • 1 egg: Adds moisture and binds the dough together.
  • ½ cup creamy peanut butter: Gives the cookies their signature flavor; avoid natural peanut butter for best results.
  • 1 tsp vanilla extract: Enhances the overall flavor.

For the Spider Decoration:

  • 44 Whoppers (or other malted milk balls): These make the “heads” and “bodies” of the spider.
  • 1 cup semi-sweet chocolate chips: Melted for creating the spider legs.
  • 1 small tube white cake decorating gel: Used to add the whites of the spider’s eyes.
  • Black nonpareil sprinkles (optional): For the pupils of the eyes.

Notes

  • Make it Kid-Friendly: Encourage kids to help assemble the spiders! Give them the task of placing Whoppers on the cookies and adding legs and eyes. This makes for a fun family baking experience.
  • If Chocolate Seizes: If the chocolate becomes too thick while piping, simply place the piping bag into a zip-lock bag and immerse it in warm water until the chocolate loosens.
  • Skip Rolling in Sugar: For a smoother texture, you can skip rolling the dough in sugar. However, the sugar adds a nice contrast to the soft interior.
