I googled it and found this:
Substitutions
For 1 cup of cake flour, substitute 1 cup minus 2 tablespoons all-purpose flour. You also can try substituting 3/4 cup all-purpose flour plus 2 tablespoons cornstarch for every 1 cup of cake flour called for in a recipe. To substitute cake flour for all-purpose flour, use 1 cup plus 2 tablespoons cake flour for every 1 cup all-purpose flour called for in a recipe.
If a recipe for a delicate cake, such as angel food or sponge cake, calls for cake flour, do not try substituting all-purpose flour. Such a substitution could cause the delicate cake to collapse.
I was about to post on this same topic. Does anyone know if this substitution actually works? I have 25lbs of all-purpose flour that I'd like to use to make cakes but I want them to work!
i substitute cake flour with a mix of allpurpose flour and cornstarch all the time (7 parts AP flour : 1 part cornstarch = cake flour)
try testing the substitution on a cake recipe and see if it works
Thanks, For posting this forum I always wondered about it, Just never got around to asking. There are a lot of CC recipe I want to try now.
