A mungie cake is a derogotory term that Canadians of European descent use to describe:
1. Canadians of mixed ethnic heritage who lack a single, pure ethnic identity
2. The first-generation born children of European-born parents who have completely assimilated or blended into the general cultural landscape of Canada.
Those unaware or so far removed from their European cultural and ethnic heritage are also referred to as a mungie
or a caker
The term is derived from the Italian word "manga" which denotes a "plain white sponge cake".
