It consists of a filled wafer, caramel (32%) and crisp cereal (26%), covered in milk chocolate (42%). It was introduced by Eric Nicoli of Rowntree's in the 1970s, after a trial in the Dorset area in 1977. It was in some areas known as Big Cat until the late 1990s. When Nestlé acquired the brand in 1988, the recipe was changed as it used to contain peanuts, as was the packaging.
In the United Kingdom, BlackWhite, White Lion, and Peanut Butter Lion limited-ion bars have also been available, as well as a "king size" variety. The bar is occasionally found in the U.S., Canada, Tajikistan, Bulgaria, Brazil, South Africa, Australia, and New Zealand in European import shops, although a similar bar, Mr. Big, is made by Cadbury in Canada.
In recent years, the Lion Bar has been dramatically reduced in size, which has caused controversy among fans.
A Lion Bar cereal, called "Lion Cereal", is made and is sold in Europe, later the UK and Ireland, as well as the Middle East. It is produced in France by Nestlé. It was first produced in the early 2000s until 2003. In 2011, a slightly different version was released.
