A favorite for children and grown ups alike. A combination of corn syrup, peanut butter, and Rice Krispies with your choice of ice cream or yogurt sandwiched in between.Place a piece of plastic wrap on top of the cereal mixture and then press down with your hands if you wish to keep your hands clean. I keep a plastic quilt ruler with my baking supplies for measuring squares and pastry. From a magazine clipping. No baking required!
