Texas Buttermilk Sheet Cake

Raven Higheagle


A delicious Texas sheet cake with chocolate frosting. Note: The frosting is a little scant for a larger sheet cake, so do feel free to double the frosting, and add more milk, as needed. It should be almost thin enough to pour onto the cake. It will firm as it cools.
