Kit Kats are my favourite afternoon snacks. I always need to have a small piece of chocolate or biscuit when i drink my afternoon tea and kit kat is my chocolate of choice. It just goes so well with tea! I often buy the snack packs (rather, the fun size from the supermarket) so you get two little pieces of kit kat and according to the packet information there is only 95 calories in those two pieces so not bad at all.
