One cup, side by side
Is this bleached or unbleached cake flour?
Unbleached. King Arthur's unbleached cake flour is 120 g per cup — the same as all-purpose and bread flour on this site. Bleached cake flour is nearer 113 g per cup, about 6% lighter, so if your bag says bleached then a cup of it weighs a little less than the number here. The two are not interchangeable by weight.

The two readings coincide only for an ingredient that happens to weigh eight ounces to the cup.
