What is the most favourite Chocolate Bar worldwide? Wunderbar has a chewy peanut butter filling with rich caramel, rice crispies and is covered with milk chocolate. What about Snickers, Mr Big, KitKat or Reese’s Peanut Butter Cup? It seems that the world is having trouble trying to choose just one favorite. Near the top on the World List though, is Cadbury Dairy Milk. Do you agree?
