Cadbury Boost is a chocolate bar made by Cadbury Ireland in the Republic of Ireland, and sold in the UK by Cadbury UK and also sold in Australia and South Africa. The bar is made up of milk chocolate with caramel and biscuit filling and called Boost as it has a high glucose content. As the wrapper states it is “Charged with glucose.”
Boost was launched in 1985 as a tough coconut and caramel bar, coated in chocolate (in a red wrapper). It was then relaunched in a further two variants: a peanut version with peanut butter (yellow wrapper) and a biscuit version (blue wrapper). The coconut version is no longer available. The peanut variant is now called a Starbar. Starbar originally existed before peanut Boost but was taken off the market and rebranded. Then Cadbury’s changed their mind and rebranded it as Starbar again. The biscuit version is now the standard Boost bar. A further version was launched in the UK in 2002 with a green wrapper: this contained guarana, was marketed alongside the biscuit Boost and advertised with the slogan “Boost Guarana: One Step Ahead”.
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, Miriam Rynne attempted to convince people that Boost bars are known as Moro bars. A peanut Moro bar is part of the range. In 2007 there was 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.
In 2009 the Boost packaging was redesigned and now includes the Cadbury name on the front. Also the Boost Duo was launched; two smaller Boost bars in one wrapper.
