In a large bowl combine the cake mix, pumpkin butter, and egg until no longer lumpy. Fold in the chocolate chips if desired. (batter will be sticky)
Use a small cookie scoop or two spoons to drop cookie dough by the teaspoonful onto a lightly greased, or silicon lined baking sheet. Bake for 10-13 minutes. Let cool for 2 minutes on baking sheet before placing on cooling rack. Enjoy!
If storing in an airtight container, place a sheet of wax paper between layers of cookies to prevent sticking.
