The beloved American baked treat has been around for more than 100 years, having made its debut in the U.S.A. at the end of the 1800s -- though its exact origins are uncertain. Legend has it that the confection occurred as a lucky mistake -- one cook didn't have enough flour for a cake, another forgot to add baking powder to make her chocolate cake rise properly, and yet another may have added melted chocolate to a batch of cookies.
Either way, we're grateful the condensed chocolate cake came into existence. Happy National Chocolate Brownie Day!
