Family recipe ( plum cake) no substitutions allowed. It calls for an 8 by 11 pan which I do not have, I am not much of a baker. I do have an appropriate size Corningware casserole probably 2 inches deep. Can I use this? Alternatives would be to find a disposable or break down and purchase something. It is a very simple yellow cake topped with halved plums and a streusle topping.
