For which 1893 Chicago event was the Palmer House Brownie requested?

The Palmer House Brownie was requested for the 1893 World’s Columbian Exposition in Chicago.

The exposition, also called the Chicago World’s Fair, was a huge international event held to commemorate the 400th anniversary of Christopher Columbus’s arrival in the Americas. It attracted visitors from around the world and helped showcase new architecture, technology, food, and entertainment.

According to the Palmer House origin story, Bertha Palmer wanted a compact dessert suitable for women visiting the exposition. It had to fit into boxed lunches and be easier to handle than a slice of cake. The hotel’s pastry chef produced a chocolate dessert that became associated with the Palmer House name.

The other options refer to different expositions. The Pan-American Exposition took place in Buffalo in 1901, the Louisiana Purchase Exposition was held in St. Louis in 1904, and the Century of Progress was Chicago’s 1933–1934 world’s fair. None matches the 1893 Palmer House account.
