Cadbury's Coconut Boost Coconut was the original flavour of boost, and then they brought out the biscuit and peanut. The biscuit sold so well that they dropped the other two flavours. I remember loving the coconut boost, but switching allegence to the biscuit flavour. I blame myself for the demise of the coconut boost. If only I'd kept buying it, maybe it would still be around now.....
