Cadburyâs âgreatestâ chocolate block yet Dreams really do come true! The chocolate maker has released a new chocolate combination and fans have dubbed it the âgreatestâ ever. Food & Entertainment by Shireen Khalil Cadbury has done it again. Just two months after chocolate fans lost their minds when the confectionary makers confirmed it had combined two cult favourites - Caramilk and Marble - it has revealed there's another mash up for us to enjoy. This time it's a Caramilk and Top Deck collab and already there is hype after the new block was spotted at an IGA store. Itâs true â thereâs now a Caramilk Top Deck block.
