In 1987 the Mrs. Fields Corporation devised a rather clever treat called the Peanut Butter Dream bar-a delicious combination of peanut butter, chocolate, and a cookie-crumb crust. It was not only a tasty product but an economical one. Mrs. Fields has always had the policy of removing cookies that are more than two hours old from outlet display cases. Now, instead of being thrown away, the cookies are crumbled up and mixed with melted butter to form the Dream Bar crust.
If you can't talk your local Mrs. Field's outlet into giving you old cookies, make your own using my recipe found here.
