This recipe comes from the 1992 M.E.I. Cookery Carousel, Volume 2 cookbook and I think I made this treat for every school event my kids were required to bring a snack to, always coming home with an empty pan. In fact, I think I could recite it from memory as so many people would ask me for the recipe. Of course, that was back in the day before the peanut allergies prevented bringing any food containing peanut butter. I have not tried substituting another nut butter nor have I tried using anything else besides corn syrup as a sweetener. This recipe just is what it is, a much-loved family treat that will make any peanut butter lover in your life a happy camper!
