Preheat your oven to 350°F (175°C).

In a large mixing bowl, combine the creamy peanut butter, granulated sugar, egg, baking soda, and vanilla extract. Stir together until a smooth dough forms.

Using a tablespoon, scoop out portions of dough and roll them into balls. Place on a baking sheet lined with parchment paper, leaving space between each ball.

Lightly flatten each dough ball with your fingers or the bottom of a glass.

Bake for about 10-12 minutes, or until the edges are lightly golden.

Press chocolate chips into the tops of the cookies to resemble eyes.

While still warm, insert pretzel sticks into the sides to form spider legs.

Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack.

Enjoy your adorable creations!
