A custard cream is a type of sandwich biscuit popular in the British Isles, and parts of the Commonwealth, filled with a creamy, custard-flavoured centre.
Traditionally, the filling was buttercream (which is still used in most homemade recipes) but nowadays cheaper fats have replaced butter in mass-produced biscuits.
[1] Usually, they have an elaborate baroque design stamped onto them, originating in the Victorian era and representing ferns.
[2] Some British and Irish supermarkets produce their own brand versions, with flavour variations including lemon, orange, banana, chocolate, strawberry, coffee, tangerine, rhubarb & custard and coconut.
[3] In the same year, a humorous study by Mindlab International listed custard creams as the most likely biscuit to cause injury or harm, scoring a so-called "risk rating" of 5.64.
