Measuring cake flour

Cake flour is milled finer than all-purpose flour from low-protein wheat, usually 7 to 9 percent, and most is chlorinated, which lets a batter hold more sugar and liquid without collapsing. That fine milling gives the tender, even crumb you want in layer cakes, chiffon and angel food.

A cup weighs about 114 g when spooned in lightly and leveled. Cake flour compacts easily in the bag and clumps, so stir it first. The 6 g difference from all-purpose flour is small, but the protein difference is what you are paying for, so do not treat the two as interchangeable.

Substituting for cake flour

If you only have all-purpose flour, measure 1 cup, remove 2 tablespoons, add 2 tablespoons of cornstarch, and sift the mixture together several times to distribute the starch evenly. The result is close but not identical to real cake flour.

Do not confuse cake flour with self-rising flour, which has baking powder and salt added. Two cups of cake flour weighs about 228 g, and a recipe that calls for 2¼ cups is about 257 g. If a recipe gives a weight, use it: layer cake recipes are tuned to the exact ratio of flour, sugar and eggs.

Frequently asked questions

How many cups is 100 grams of cake flour?

100 g of cake flour is about 0.88 cups.

How many grams is a tablespoon of cake flour?

About 7.1 g, based on 114 g per cup and 16 tablespoons per cup.

How many cups is 500 grams of cake flour?

About 4⅜ cups, since 500 g divided by 114 g per cup is just under 4.4.

Can I use all-purpose flour instead of cake flour?

Yes, with the cornstarch trick above. For delicate cakes, the real thing gives a finer crumb.

Should I sift cake flour before measuring?

Follow the wording in the recipe. If it says "sifted cake flour", sift before measuring. If it gives grams, weigh the flour and sift afterward only to remove lumps.
