Preheat oven to 350 degrees.

In a bowl, combine peanut butter, dry cake mix, oil, and eggs. Stir until well combined. This is a pretty stiff dough, but it will mix together.

Stir in chocolate chips.

Shape dough into balls about 1 inch in size. Place on cookie sheet about 2 inches apart and flatten dough slightly.

Bake for 9-11 minutes.

Let cool on cookie sheet for 5 minutes, and then remove to wire rack to cool.
