Cake Flour is milled from soft (lower protein) white flour. It has a lower gluten content than pastry flour, and a far lower gluten content than bread flour. Cakes need to be light and fluffy and have a very fine texture, thus you don't want a lot of gluten developing in the batter. The flour has a pale beige or yellowish colour which is lightened with bleaching. The bleaching, apparently, also strengthens the flour, allowing it to support better the weight of the sugar and fat in the cake. The flower is usually pre-sifted (several times) before packaging, and sometimes, cornstarch is added.

Cake flour is usually sold in smaller quantities than other flour is.

Some people say that using cake flour instead of all-purpose flour tends to keep cookies from spreading on cookie sheets (its lower protein content ties up less moisture making it available for steam production. Steam lifts the batter in the oven producing a fluffy, cake-like batter.) Other people say cake flour is usually too tender for cookies. Use all-purpose flour or plain flour unless otherwise instructed.
