I turn 40 tomorrow and, unbelievably, don't yet have a rice crispie cake recipe in my repertoire. In my defence, my toddler is only 19 months old so I haven't had to do the school cake stall thing yet. Anyway, I want to make some with her that she can give to Grandma for her birthday, so can you please share your best recipes? Should they be pure chocolate, but liable to remove a tooth, or should they have some butter and golden syrup in the mix...?
