But thanks to some eagle-eyed fans, thereâ€™s a surprising way to hunt down the sought-after egg without having to eat your way through the shelves.
All you have to do is check the nutritional information on the wrapper, as itâ€™s a legal requirement to list all ingredients on a food or drink product in the UK.
Yes, it really is that simple.
On regular Creme Eggs, the words â€œmilk chocolateâ€ come first in the ingredients run-down followed by â€œmilk solids, vegetable fats and cocoa butterâ€.
Whereas a white egg should list â€œwhite chocolateâ€ instead.
In fact, Cadburyâ€™s almost gave the game away as the company announced: â€œAll white Cadbury Creme Eggs, while wrapped in the same iconic packaging as the classic Creme Egg, will contain nutritional information that is specific to the white chocolate variant.â€
Last year, Cadburyâ€™s released just 371 white chocolate Creme Eggs across the country with a top prize worth Â£2,000 â€“ although nobody ever found it.
This year, the chocolate giant has upped the stakes by dishing out a grand total of 783 white chocolate eggs to supermarkets including Tesco, Sainsburyâ€™s, Morrisons and Asda.
There are eight white Creme Eggs worth Â£10,000 up for grabs with other cash prizes ofÂ Â£50, Â£100 and Â£1,000 also on offer.
If you hit the jackpot, youâ€™ll need to call the phone number printed on the voucher inside the chocolateâ€™s foil wrapping. The competitionÂ ends on April 21, 2019.
