This chocolate sheet cake recipe is a bake from scratch chocolate cake with chocolate icing.

The original recipe was found written on a 4×6 notecard and found among the many other recipes in our Vintage Map recipe box.

It is hard to say when this recipe may have been first introduced, but there is a clue in the fact that it mentions Eagle Brand sweetened condensed milk.

Eagle Brand Sweetened condensed milk first originated in 1856. It was a very important product because back then it was very difficult to keep milk from spoiling.

Doing a little research, we did indeed find this chocolate sheet cake listed on the Eagle Brand condensed milk website – along with one reviewer who said she had been making this cake for over 25 years.

Because it includes a brand-specific ingredient, it is most likely this recipe was included in a vintage advertisement for Eagle Brand condensed milk at some point. However, the nuts as a topping also tipped us off that this might be a variation of Texas Sheet Cake.

Texas sheet cake is typically made with pecans and buttermilk – this variation does not specify which type of nuts to use and uses condensed milk as a substitute for buttermilk. We’ve also found quite a few Texas sheet cake recipes that use sour cream in place of the milk, and even a few that used a coconut topping instead of a fudge topping.

If you’re not familiar with the different cake sizes, a sheet cake is a single layer cake that is perfect for large gatherings of people.

This recipe calls for a 10×15 pan size, which is usually found as a jelly roll pan. Jelly roll pans are only about 1 inch tall.
