Chocolate brownies are a very common family snack in the United States, with a taste between biscuits and cakes. Brownie cake is a kind of heavy oil cake, but different from ordinary heavy oil cake, it is usually thin and compact, not as loose as ordinary cake, and it must be chocolate-flavored, decorated with almonds or walnuts, and usually sweet.

Chocolate brownie, also known as chocolate brownie cake, walnut brownie cake or Boston brownie-a lovely chocolate cake.
It is said that a fat old black mammy wore an apron to make soft chocolate cakes in the kitchen, but forgot to deliver the cream first. The cake was wet and dense, and it became an unexpected delicacy. This lovely mistake makes Brownie the most representative cake in American families now.
