I buy boxes of broken biscuits, mostly not very broken, because it's cheaper, and my most frequent visitor eats through huge quantities. But I now have a tinful of bits that are two small to eat as biscuits. I have made refrigerator cake, and found a recipe for a biscuit pudding on the same lines as bread pudding.
I don't need any cheesecake just now, and have enough crumbs anyway.
Any ideas? Preferably something that I can eat very quickly or that keeps very well.
