The Kit Kat requires little explanation, but here goes: each finger comprises three layers of wafer encased in delicious milk chocolate. Kit Kat was first launched by Rowntrees in 1935, and remains the perfect in-between meal treat.

The 4 fingers are perfect for (a) sharing amongst friends, work colleagues, etc; (b) eating in separate sessions across the course of a day; or (c) munching down in one go! The choice is yours.
