Preheat oven to 350°F (175°C).

In a large mixing bowl, combine the yellow cake mix, creamy peanut butter, oil, and eggs. Mix until a smooth dough forms.

Using a spoon or cookie scoop, drop rounded tablespoons of dough onto an ungreased baking sheet, spacing them about 2 inches apart.

Flatten each cookie slightly with the back of a fork, creating a crisscross pattern.

Bake for 10-12 minutes until the edges are set and the cookies are lightly golden.

Allow cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
