Notes

  • Butter: When it comes to Cake Mix Cookies, salted or unsalted butter can be used, as the cake mix will have a little salt in it.  However, I’ve found that salted butter will result in superior flavor.

        does it have to be Betty Crocker’s? super moist cake mix or can you use an old brand name like Giants or Weis market or Walmarts?

          Hi Barbara ~ you can substitute other brands, but you’ll want to pay attention to the ounce size on the box. Betty Crocker recently reduced their cake mix box from 15.25 oz. to 13.25 oz. If using a 13.25 oz. box, you’ll want to use 1/3 cup melted butter or oil, but if using a larger 15.25 oz. box, you’ll need to increase that to 1/2 cup melted butter or oil. Hope that helps! The two eggs will stay the same, regardless the size of box. Hope that helps! 🙂

    Making the Kit Kat cookie. Looks so good! My question is – after you refrigerate the dough for an hour should it still be sticky? Should I be able to roll in a ball? Or just spoon onto cookie sheet??

    Reply
    1. Heidi says:

      Hi Lena ~ the dough will still be somewhat sticky because of the oil, but you should be able to roll it into balls just fine after refrigerating. Sometimes I pop the dough back into the refrigerator while the cookies are baking, so it can remain chilled until I’m ready to use it again. Hope that helps… and enjoy your cookies! 🙂
