To substitute all-purpose flour for cake flour, you can try using 1 cup of all-purpose flour minus 2 tablespoons, and then add 2 tablespoons of cornstarch. This will help to reduce the protein content of the flour and create a lighter, more tender crumb. It's a bit of a hack, but it works like a charm.
Another option is to use a combination of all-purpose flour and pastry flour, which has a lower protein content than all-purpose flour. This will give you a more delicate texture and a more complex flavor profile. And, if you're feeling fancy, you can even try using Italian "00" flour, which is a type of flour that's perfect for delicate baked goods.
