Texas Sheet Cake

Texas sheet cake is a brownie-like cake, only one-inch thick and often served on a cookie sheet. “Texas sheet cake” is recorded from the 1960s, but “sheet cake” is recorded earlier. The below article claims that this cake is a cousin to German Chocolate Cake, and that Texas ingredients such as buttermilk and pecans helped to make it popular.
 
Similar to “Texas sheet cake” is “Texas sheath cake” (a name used since at least 1950). Why the different names? ‘Sheet” often sounds like something that cannot be printed here, and the name was probably changed because of that.

Texas Sheet Cake

The first time you eat a piece of Texas sheet cake, chances are you’ll say to yourself, “This cake tastes familiar. Where have I run into it before?” It’s a reasonable reaction because Texas sheet cake is very closely related to German Sweet Chocolate Cake, so close that with your eyes closed, it could be a bit of a push to tell the difference.  Both are chocolate cakes covered with a sugary coconut-pecan frosting. One is baked in layers, and the other in a single pan, but you don’t know that until you open your eyes.

The connection, say culinary historians, is that German Sweet Chocolate Cake was what inspired Texan cooks to create their famous sheet cake. The origin of Texas sheet cake is unclear; the story behind German Sweet Chocolate Cake is easier to explain.  (...)

Both the German Sweet Chocolate Cake and Texas sheet cake recipes call for two of Texans’ favorite ingredients: buttermilk and pecans.  The big difference is that the sheet cake is infinitely easier to put together.  Instead of melting chocolate, creaming butter, and beating egg whites, all of which are involved in making German Sweet Chocolate Cake, everything for Texas sheet cake is stirred together in one large bowl.  The frosting recipe for both cakes is similar. The German Sweet Chocolate Cake is a stacked 3-layer structure filled with frosting, which takes a little more doing. Given our druthers, we go for the sheet cake.  It’s a big old-fashioned cake, easy to transport and a real crowd pleaser.

The Texas Sheet Cake is a brownie-like chocolate overload of a cake. It’s a low, flat cake with a metallic-like shiny chocolate icing. When I was younger I used to demand it for my birthday. Now I just make it myself (although not as well). It’s sweet and yummy and just plain good…

The Most Popular Recipes of the Twentieth Century

Pg. 459:
Texas sheet cake. One of my all-time favorite cookbooks is a little spiral-bound paperback called Food Editors’ Hometown Favorites published in 1984 by the Newspaper Food Editors and Writers Association. It is appears this heavenly chocolate cake spread with fudge-pecan icing. it was contributed to the book by Dotty Griffith, food editor of the Dallas Morning News. But the accompanying headnote says the recipe was also submitted by food editors all over the country. Some attribute the cake to Lady Bird Johnson. Others say it got its name because it’s as big as Texas—well, not quite. The cake couldn’t be easier to make, it’s suprisingly light, but my, it is sweet.”
 
28 January 2001, Charleston (SC) Post and Courier, “A chocolate cake from the land of the supersized” by Ann Burger, section G, pg. 6:
WHAT’S COOKIN’?
Question: Where does Texas Sheet Cake get its name?
 
A) From the super-chocolatey taste, as big as Texas.
B) From the fact that the taste is so intense, people can eat only a small piece—meaning one cake will serve a Texas-size crowd.
C) From its overall richness—a big taste in a big cake from a state that was supersizing things long before fast-food places were.
D) All of the above.
 
The answer, if you’ve ever tasted the famous cake, has got to be D. Texas Sheet Cake is chocolate through and through, rich and decadent. As for whether it originally came from Texas, I couldn’t find a definite answer. But Lone Star cooks were smart to get their state’s name on something that tastes so good.
