What is the origin of "granny cake"? Why is it called "granny cake"?

The old woman cake originated from Chaozhou dim sum old woman cake in Guangdong Province. The outer skin is baked into attractive golden yellow, and the layers of pastry inside are as thin as cotton paper. Very crisp. Take a bite and the crumbs will fall all over the floor. Every bite will taste the sweetness like honey! The cake made by my wife is loved by my boss.

It is a traditional scenic spot in Chaozhou City, Guangdong Province. It is made of sugar wax gourd, wheat flour, cake powder, maltose, sesame and other ingredients as the main raw materials. Guangdong Chaozhou moon cakes are cakes with the least materials, the simplest workmanship and the highest reputation.
