Who invented chocolate wafer bars?

There isn't one single inventor of the chocolate wafer bar. It's more of an evolution of ideas!

Here's a breakdown of key figures and milestones:

* Early wafer production: Wafer technology, using thin, crisp layers, existed for centuries. This was used in biscuits and pastries.

* 19th century: Chocolate manufacturing became more advanced, paving the way for chocolate wafers.

* 1900s: The Cadbury Brothers are credited with creating the first commercially successful chocolate wafer bar (the "Bournville Chocolate Crisp").

* 1911: The iconic Kit Kat bar was created by Rowntree's in the UK. This bar cemented the popularity of the chocolate wafer format.

Since then, countless companies have created their own variations of chocolate wafer bars, each with unique fillings, flavors, and textures. So, while no single person can claim to have invented it, the chocolate wafer bar owes its existence to a combination of innovation and evolution over time.
