The term chocolate bar is a popular way of describing a confectionery treat in the form of a bar. This is usually packaged in a bar shape with individual perforations or in a long, narrow, shaped log covered with chocolate. Many types of chocolate bar exist and there are thousands of companies that create chocolate bars. Some of these companies produce many choices of fillings in their chocolate bar, such as nuts, fruit, mint, coconut, marzipan and many more.
The chocolate bar evolved in approximately the late 1900s. Chocolate had become popular many years before the introduction of the bar but the idea of creating a chocolate bar was to provide a more convenient way of consuming the chocolate. The bars could be packaged and sold to eat easily by hand or while on the go. Up to the invention of the chocolate bar, chocolate had been sold by bulk with loose, irregular or formed pieces.
