Preheat oven to 350 F (175 C) and line baking sheets with parchment paper.

In a large bowl, mix the cake mix, creamy peanut butter, oil, and eggs until a soft dough forms.

Roll into 1.5 tablespoon balls, place on baking sheets, and press with a fork in a crisscross pattern.

Bake for 10-12 minutes until edges are lightly golden. Centers will remain soft and firm up as they cool.

Cool on the pan for 10 minutes, then transfer to a wire rack. Serve with cold milk!
