Why measuring cake flour by cup goes wrong
Cake flour is finely milled and bleached, with 7–9 percent protein. It absorbs less liquid and produces a softer, finer crumb than AP. The lower protein and finer mill mean a cup weighs noticeably less (114 grams vs. 120 for AP) — even though it feels feather-light in the hand, it's not that the volume is wrong, it's that the particles pack more loosely.
Practical tips for working with cake flour
If you have AP but the recipe demands cake flour, the standard workaround is to measure one cup of AP, remove two tablespoons, and replace those two tablespoons with cornstarch. Sift the mixture three times before using. It's not perfect — bleached cake flour interacts with high-sugar batters in a way the substitute cannot replicate — but for everyday layer cakes it's close enough that most tasters won't notice.
Note from this ingredient's record: Finely milled and lower in protein. If a recipe calls for cake flour and you only have AP, swap two tablespoons of every cup for cornstarch.
