It's not birthday cake in our family unless it's Overnight Cake with Mock Whipped Cream frosting.
Overnight cake is a mock angel food cake that really takes 2 days to make. You start by combining cake flour and sugar with boiling water, and letting it sit covered on the counter overnight. The next day you beat egg whites, almond flavoring and cream of tartar until stiff, then fold in the first mixture.
Mock whipped cream frosting is almost as fidgety. Boil flour and milk mixture, cool, and add to whipped butter, crisco and sugar mixture.
We were able to find a baker who would make this cake for our wedding. It was wonderful to have my favorite cake for our wedding.
