Ok, I tried making them tonight. Jell-O comes in 3oz boxes & 6oz boxes. Recipe didn't say which but the 3oz seems about right. Used Kellogs corn flakes because they were 3 big boxes for 5 bucks. You gotta work fast when mixing because the Jell-O gels after a while. Use flour when forming. The instructions called for 4 hours bake time. The bars burnt after 2 hrs. They have a sickly sweet flavor. Gooey texture. Thumbs down on this recipe for poor nutrition and instructions.
