I always double the receipe, they are so good, easy and quick!
I box cake mix (your favorite)
1/2 cup veggie oil
Mix cake mix (don't follow directions on box...Just add the mix), eggs and oil. Is a bit dense but should be. Bake at 350 degrees for 8-10 minutes...or until done. Lets face it...ovens are different.
Toppings...add frosting of any kind but they are delicious alone. These were made with devil's food cake mix. They are like a crunchy piece of cake. (I tend to like crunchier cookies so I leave them in 11 minutes).
My motto KISS (and that applies to cooking too)
