June 1905, Cadbury's launches its first Dairy Milk bar, with a higher proportion of milk than previous chocolate bars

In Australia, Cadbury Dairy Milk was reformulated in 2006 and again in 2009, with the addition of palm oil as a replacement for some cocoa butter. (This occurred in conjunction with a weight reduction of the standard block from 250g to 200g.)

The U.S. Food and Drug Administration does not allow products that replace cocoa butter with vegetable fat to be called chocolate.

In the UK Cadbury's bar cocoa comes fourth after sugar, milk, and cocoa butter (Milk, Sugar, Cocoa Butter, Cocoa Mass, Vegetable Fat, Emulsifier: 442, Flavourings)

However the Black and Greens bittersweet dark chocolate bar, packed with 70% cocoa solids is now also owned by Cadbury's
It is one of my favourite and your post strikes a little fear into my heart
