Not that an excuse is really needed, but Brownie Day is a great chance to bake a batch of luxurious chocolate brownies. Serve them up with cream, ice-cream, toasted nuts or any of your favourite little luxuries to make it a perfect moment! A chocolate brownie, or just 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 i, 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.
