How to measure cake flour

Cake flour is very finely milled — sift it before measuring for the lightest possible crumb.

Because a cup measures volume rather than weight, the most reliable way to measure cake flour is with a digital kitchen scale. If you are working from cups, keep your technique consistent every time so your results are repeatable. For more, see our guide on baking by weight versus volume.

Substitutes for cake flour

1 cup cake flour = ⅞ cup all-purpose flour (14 tbsp) + 2 tbsp cornstarch, sifted together (King Arthur Baking / America's Test Kitchen)
Cornstarch dilutes the AP flour's protein to mimic cake flour's tender crumb. Sift the blend two or three times so the cornstarch distributes evenly.

Cake flour conversions: FAQ

Why doesn't a cup of cake flour weigh the same as a cup of water?

A cup measures volume, not weight. Cake flour is less dense than water (120 g versus 237 g per cup), so the same volume has a different weight. Weighing in grams is the most accurate way to measure it.
