A chocolate bar or candy bar is a confection containing chocolate, which may also contain layerings or mixtures that include nuts, fruit, caramel, nougat, and wafers. A flat, easily breakable, chocolate bar is also called a tablet. A wide variety of chocolate bar brands are sold. A popular example is a Snickers bar, which consists of nougat mixed with caramel and peanuts, covered in milk chocolate.
The first solid chocolate bar put into production was made by J. S. Fry & Sons of Bristol, England, in 1847. Cadbury began producing one in 1849. Released in 1866, a filled chocolate bar, Fry's Chocolate Cream, was the first mass-produced chocolate bar. In 1912, the Goo Goo Cluster was the first mass-produced combination bar; it included marshmallow, nougat, caramel, and roasted peanuts. In some varieties of English and food labeling standards, the term chocolate bar is reserved for bars of solid chocolate, with candy bar used for products with additional ingredients.
A wide selection of similar chocolate snacks or nutritional supplements are produced with added sources of protein and vitamins, including energy bars, protein bars and granola bars.
