How to Measure Cake Flour Accurately
Cake flour is milled extra-fine and clumps in the bag, so sift it into the cup — or spoon it in after a stir — and level with a knife. A packed cup of cake flour can weigh 140 g instead of 115 g, which is the difference between a light chiffon and a heavy slab. Never tap the cup to settle it.
Storing Cake Flour & Common Substitutes
Storage
Sealed and cool, 6–8 months for the best leavening performance. The fine grind goes stale and slightly rancid faster than heartier flours because more surface area is exposed to air; smell it before an important bake. Refrigeration is fine if you bring it to room temperature first.
Substitutions
Make your own: for each cup, measure 1 level cup of all-purpose flour, remove 2 tablespoons, and add back 2 tablespoons of cornstarch; sift together twice. Pastry flour is the closest commercial 1:1 swap (115 g per cup).
