The birthplace of the brownie can be traced to the kitchen of a Chicago hotel.
So claims the Palmer House, a Hilton hotel that has been operating in downtown Chicago since 1873 (the original hotel was built in 1870 but burned down during the Great Chicago Fire a year later).
Bertha Palmer, wife of Chicago businessman and Palmer House founder Potter Palmer, helped invent the chocolate brownie when she directed the hotel kitchen staff to come up with a confection smaller than a piece of cake for women attending the World's Columbian Exposition — better known as the Chicago World's Fair — in 1893, according to the hotel's website.

Now, more than 130 years later, the same recipe is still used to serve brownies at the Palmer House today, Scott Gourley, the hotel's executive chef, told Fox News Digital.
"I probably upgraded the ingredients a little bit since then," he admitted.
The first reference to the "brownie" in America appeared in the Sears Roebuck catalogue, published in Chicago in 1898, the Palmer House claims on its website.

It remains one of the hotel's most popular confections, Gourley said.
The brownies are such a draw that people will come to the hotel and buy 40 or 50 of them at a time, he said.
"We sold approximately 58,000 of them last year," Gourley said.
"And we're already on pace to surpass that this year."
