A chocolate brownie is a flat, baked square or bar
introduced in the United States at the end of the nineteenth
century and popularized in both the U.S. and Canada during
the first half of the twentieth century. The brownie
is sliced from a type of dense, rich chocolate cake, which
is, in texture, like a cross between a cake and a cookie.
Brownies come in a variety of forms.
They are either fudgy or cakey, depending on their
density, and they may include nuts, frosting, whipped cream,
chocolate chips, or other ingredients. A variation that is
made with brown sugar and no chocolate is called a blondie.
Brownies are common lunchbox fare, typically eaten by
hand, and often accompanied by milk or coffee. They are
sometimes served warm with ice cream (a la mode) or topped
with whipped cream, especially in restaurants.
