  • Spread icing on top of the base. Refrigerate to set. Cut into squares. Can be stored at room temperature.


I made this recently with honey in place of corn syrup and it turned out good. (I also used all Rice Krispies because I didn't have any Corn Flakes.)

    I have been making these for years this exact same recipe and it is my favorite and every one else who tastes it. We’ve taken it camping and I’ve made them when we’re camping. With the brown sugar icing it’s a great change from chocolate!

    My mother(who is 90) introduced me to this recipe over 40 years ago through a bridge friend during a potluck lunch and I have been hooked ever since! (My husband thinks it is too sweet!!) Oh well… more for me!! ❤️
