The German's Sweet Chocolate Cake
Unlike the name suggests upon first hearing, German's Chocolate cake is not from Germany not of German origin, rather, it hails from Texas.
German's Sweet Chocolate was invented by Sam German of the Baker's Chocolate Company back in 1852, in an effort to lower the amount of sugar (which was comparatively expensive back then) a home cook would need to add to a recipe. It is 48% Cocao Solids and contains NO dairy, unlike Milk Chocolate (which is usually not above 28%) and Semi-Sweet Chocolates.
The German's Sweet Chocolate Cake, however, is a relative newcomer to the confection scene. The recipe was first published in Texas in a newspaper in 1957. Due to it's popularity, the recipe became the "Poster Child" for the brand and has been published in many newspaper across America.
There are many "copies" of the recipe using substitute ingredients, like mixing milk and dark chocolates together. A German's Sweet Chocolate cake is made WITH German's Chocolate, if it is not, then it is simply a Chocolate Cake.
