Rose Mary Rolf's Clark Gable Cake

Rose Mary Rolf (ne. Kraus), was my aunt on my mother's side. She was also my godmother with a prankster sense of humor. 

Rose Mary Rolf's Clark Gable Cake

Combine in large mixer bowl:
1 cup lard
2 eggs
2 cups sugar
Beat thoroughly.

Sift 3 cups all purpose flour with 6 tbsp cocoa in 1/2 cup hot water
(Recipe says "Add milk to completely fill 2 cups" WHAT?!
"Now add to that same cup 2 tsp vinegar, 2 tsp soda, 2 tsp vanilla. Beat well")

Okay, so I think this means:
Add 2 cups milk.  Mix.
Add 2 tsp vinegar
2 tsp soda
2 tsp vanilla
Beat well

Bake 350* 'till done

No pan measurement given. Looks like enough volume to fill up two rounds or one 9x13
