How to measure all-purpose flour
Spoon the flour into the cup and sweep the top level with the back of a knife. Dipping the cup into the bag and scooping packs the flour down, so the same cup holds noticeably more, which is enough to make cookies dry and cakes dense. If you bake often, a kitchen scale pays for itself quickly.
Source: 120 grams per US cup is the weight per cup used by US baking charts such as King Arthur Baking’s ingredient weight chart. A US cup is about 237 milliliters.
