The confectionery giant has announced the roll-out of special white chocolate eggs across the UK, with prizes ranging anywhere between £100 and £2,000.
The eggs are much the same as the original version - down to their identical packaging - except the hidden ones have a shell made of white chocolate.
Only one of the eggs is worth £2,000, while 34 of them are worth £1,000. The rest are worth £100 each.
Early response to the white egg on social media was mixed, with Tara Evans writing: "Cadbury's has gone all Charlie and the Chocolate factory on us".
Sami Harper posted: "Desperately need to find and eat a white Cadburys creme egg, couldn't care less about winning any money from it."
Another person described it as "an abomination".
Consumers were bemused to see Easter Eggs on shop shelves almost immediately after Christmas, but Creme Eggs went on sale on New Year's Day, which is standard for the product.
US giant Kraft Foods bought Cadbury in 2010 and its global snacks business under the name of Mondelez International.
The now familiar Cadbury Creme Egg first hit the shelves in 1971.
A single Creme Egg costs 58p, while a five-pack costs £2.85 and a twelve-pack costs £6.68.
