Years ago, my sister-in-law Judy gave me a small book in which she had handwritten Garrett family recipes. I've transcribed some of them here to share with my friends on the Internet.
My mother found this recipe in the San Antonio Light and made it often when we were young. As a teenager, I baked this one fairly often.
One caveat: Don't substitute vanilla for sugar. Been there. Done that.
In a 13" x 9" pan, sift together:
3 cups flour 2 cups sugar 2 tsp soda 1 tsp salt 6 Tbsp cocoa
Make three depressions in the dry mixture and put in on depression 2 tsp vinegar, in another 2 tsp vanilla, and in the third 10 Tbsp. vegetable oil. Pour over this 2 cups water. Stir it all together, mixing well.
Bake at 350°F for 50 minutes. Doesn't need to be frosted.
