My new favorite, super easy, cake mix cookies

I don't really eat cookies much anymore, too much sugar makes me feel like I'm going to die, but these were amazing. After I listened to Jeff and Anthony go on about them I had to try one myself! (Amelia doesn't like chocolate so she didn't have an opinion. Weird child!) They were so yummy and they're super simple.
Preheat the oven to 350.
Mix together the following

1 box of cake mix (I used devils food)
1/2 cup of butter (softened)
2TB of oil
2 eggs
Then stir in 1 cup of chips (I used store brand semi sweet chocolate)

Drop by rounded spoonful on to a cookie sheet, and bake for 8-10 minutes. Mine were perfect at 8.5. Cool on the pan for few minutes then transfer to a wire rack. Or in my house just leave them on the cookie sheet, they'll eat most of them before the second batch is out of the oven!

I'm thinking I could make these with a strawberry cake mix with white chocolate chips or a butter cake for a sugar type of cookie. Have you tried this kind of recipe? What flavor combination would you make?
