The product consists of a thick chocolate shell containing a sweet white and yellow filling that resembles fondant.

[4] The fondant in each half is topped with a smaller amount of the same mixture coloured yellow with paprika extract,[4] to mimic the yolk and white of a real egg.

[8] Before 2006, the eggs marketed by Hershey were identical to the UK version, weighing 39 g (1.4 oz) and containing 170 kcal.

[14] Analysts at IRI found that Cadbury lost more than $12 million in Creme Egg sales in the UK.

[citation needed] In the United States, some green is incorporated into the design, which previously featured the product's mascot, the Creme Egg Chick.

[citation needed] As of 2015[update], the packaging in Canada has been changed to a 34 g (1.2 oz), purple, red and yellow soft plastic shell.

[22] Individuals who discovered an egg would win money via a ticket that had a code printed on it inside of the wrapper.

[23] New Zealand's Dunedin plant later received a $69 million upgrade to specialise in boxed products such as Cadbury Roses, and Creme Eggs were no longer produced there.

The adverts have continued to air nearly unchanged into the high definition era and after Adams's death in 2005, though currently the ad image is slightly zoomed to fill the screen.

[28] In the UK, around the year 2000, selected stores were provided standalone paperboard cutouts of something resembling a "love tester".

The shopper would press a button in the centre and a "spinner" (a series of LED lights) would select at random a way of eating the Creme Egg, e.g. "with chips".

[29] For the 2008/2009 season, advertising in the UK, Ireland, Australia, New Zealand and Canada consisted of stopmotion adverts in the "Here Today, Goo Tomorrow" campaign which comprised a Creme Egg stripping its wrapper off and then breaking its own shell, usually with household appliances and equipment, while making various 'goo' sounds/noises (as the only sounds and voices they make are the sole word "goo"), and a 'relieved' sound/noise when it has finally been able to break its shell.

[34] The café on Greek Street, Soho, was open every Friday, Saturday and Sunday from 22 January to 6 March 2016.
