Fact

German chocolate cake was invented in Texas.

The “German” part of German chocolate cake comes from an American man—not a European country. Specifically, it’s named after Sam German, who in 1852 created the formula for a mild dark baking chocolate bar for Baker’s Chocolate Company, which was subsequently named Baker’s German’s Sweet Chocolate.
