No, this is not the crack recipe from Breaking Bad tv series. Chocolate Cracknell is a popular dessert that was served in British schools in the 70s. To explain in simple terms, it's cornflakes in caramel with cocoa powder added, which gives the dessert its chocolate color and flavor. The texture of the chocolate cracknell on the outside is soft and stretchy, a bit like butterscotch, but you're greeted with the crunch of corn flakes as you bite into it. It's super easy to make with just about any ingredient you can think of, but it's a good idea to make your own golden syrup or get some at the store.
