Preheat your oven to 350 degrees F and line a baking sheet with parchment paper or spray with non-stick cooking spray. Set aside.
In a large bowl, mix together the cake mix, peanut butter, eggs, and oil until a thick dough forms.
Scoop the dough out into little balls about 2 tablespoons in size. *Optionally, you can roll them into granulated sugar if desired.
Line the cookie dough balls on the baking sheet allowing about 2 inches of space between each.
Bake in the oven for 10-12 minutes.
Immediately press an unwrapped Hershey kiss into the center of each ball and allow the cookies to rest on the baking sheet for about 5-10 minutes before transferring to a wire rack to finish cooling completely.
Eat warm for a soft cookie and melted chocolate bite of deliciousness or let them cool and set completely before eating or storing.
