Kraft Foods has extended its Cadbury stable in the UK with the addition of a mini variant for its Bubbly chocolate bar.

The company said the “self eat” version will be available in a smaller format and will be supported by a GBP1.5m marketing campaign to boost awareness of the product. The campaign will comprise social media, TV advertising and point of sale.
