Boost is a chocolate bar made by Cadbury in the Republic of Ireland, and sold in the UK, Australia as well as South Africa. Its wrapper says that it consists of milk chocolate with caramel and biscuit filling. The wrapper also states that Boost is "Charged with glucose."
For a while Boost was advertised on television by comedy duo Reeves and Mortimer. This led to the unconventional advertising slogan "It's slightly rippled with a flat under-side."
In Ireland, Boost bars are known as Moro bars. A peanut Moro bar is part of the range. There is currently (Summer 2007) a limited-edition coconut Moro on sale in Ireland.
The Boost bar has been released in New Zealand under the popular Moro brand as Moro Gold.
Reports surfaced in early autumn 2008 about a crusade to rename the Star Bar to Boost peanut, however little is known about the validity of this.
