So next time you buy a Creme Egg, unwrap it carefully to see if you're one of the lucky winners.
If you find a half-and-half chocolate, make sure you resist the urge to take a bite.
There is a phone number printed on the ticket under the foil covering the chocolate which you can call once you've found one.
Make sure you keep the ticket too as you'll need to prove you've won.
On the phone, you'll be asked some questions to verify your ticket, including the unique code and when it was bought.
Lyndsey Homer, brand manager for Cadbury Creme Egg, said: "When we celebrated our Golden Goobilee last year, we were absolutely blown away by the response to our golden eggs and this year, we wanted to continue that buzz in true Creme Egg fashion."
Just this time last year, Cadbury Creme Egg was giving fans the chance to win £5,000 – if they find Golden treat.
The limited edition Golden goodies were hidden in stores masquerading as the much-loved classic Creme Egg.
