According to internet legend, the inventor of the Double Decker chocolate bar was sacked for unauthorised access of the Cadbury laboratory.

Matthew Carroll, the employee who created the product, was found in the laboratory at the Cadbury factory in Chirk, just outside Wrexham, ‘experimenting’. Although the resulting experiment was a success, he was subsequently sacked for breaking strict company rules by being in the laboratory. Sounds a bit harsh, but rules are rules!

Meanwhile, the little bar went through a number of tweaks and brand refreshes, including a dalliance with nuts and raisins. This Picnic-esque version was sadly short lived, and now the chocolate bar remains lightly flavoured with coffee and structured in two layers; the upper whipped nougat, the lower layer of cereal ‘crispies’.
