How is the white and yellow filling inside a Cadbury Creme Egg made?
The short answer
The white and yellow parts of a Cadbury Creme Egg are fondant filling arranged to resemble egg white and yolk. Colour creates the yolk effect; it is not a little cooked yolk. The UK ingredient list does include dried egg white, so saying Creme Eggs contain no egg would be incorrect. [1]
The centre is a confectionery filling
Cadbury describes its product as a milk chocolate egg with a soft fondant centre. Sugar, glucose syrup and invert sugar syrup appear in the UK ingredient list. “Creme” is a product name, not a promise that the centre is fresh dairy cream.
The visual resemblance comes from contrasting white filling and a yellow portion. It is an edible imitation of an egg’s appearance. [1]
How does the yellow part look like yolk?
A small coloured portion against a much larger white background creates a familiar egg-like cross-section. The UK recipe lists paprika extract as a colour. The yellow section is not evidence of a separate natural egg yolk hidden inside the chocolate.
The current pack is the authority for the product you are holding. Formulations, sizes and market versions can differ. [1]

How it works [2]
How does the filling get inside?
A Cadbury spokesperson described the ordinary egg’s assembly as filling two halves and sandwiching them together. That makes more sense than picturing a finished hollow egg with a hole drilled into it.
The illustration below simplifies that assembly principle. It does not specify the factory’s exact machines, temperatures or dosing settings. A giant display egg is another case: Cadbury World’s chocolatier described filling that special creation differently. [2][3]
Does a Creme Egg actually contain egg?
Yes: the UK ingredient list checked for this guide includes dried egg white. Cadbury also declares egg and milk among its allergens. Do not confuse “not a real yolk” with “contains no egg ingredient”.
This matters more than the visual trick if you are buying for someone with an allergy. Use the exact current packet and official product information, rather than a generic explanation of fondant. [1]

| What you notice | What explains it |

Common questions
Is the yellow centre a real egg yolk?
No. It is part of the fondant appearance; the recipe lists a colour. [1]
Are Creme Eggs egg-free?
No. The UK ingredients checked here include dried egg white. Always check the current exact product. [1]
Is the middle filled through a hole?
A Cadbury spokesperson described the standard product as two filled halves joined together. Special display eggs can use different methods. [2]
