Here in the USA, we have mooncakes, moonpies, & moonpastries.
They are a delicate thin cake filled with marshmallow filling and folded over to create a half circle and covered with thin yellow frosting.
You can make them or buy them. We eat them year round.
What third world puts meat & veggies in a cake?
Although, we have been known to bake some "things" in our cakes....engagement rings, breaking out of jail "file" tools, and car keys.
