The brownie, a flat, baked square or bar developed in the United States at the end of the 19th Century. 

The brownie,  a cross between a cake and a cookie in texture.

The brownie, leave out the chocolate and make with brown sugar and it becomes a BLONDIE.  Maybe that's why I like brownies so much.
