I'm going to let you in on a little secret. But, shhhhhh. Don't tell anybody. <whispering...softly> Sometimes I use a packaged mix. <looks over shoulder> Not often, but I've found a few that I really like and can't really do much better. So I just buy them and tuck them away in the back of the cupboard so nobody can see.
This is probably my all time favorite: Betty Crocker's Peanut Butter Cookie Mix. It just costs a few pennies, really. But honestly, don't tell the ladies at the school fund raiser that I'm cheating with a mix. You can buy it at the grocery store or in bulk here. Make sure you put it in the back of the cupboard and throw a towel over it. You don't want anybody to know our little secret.
