How to Measure Cake Flour
Use the spoon-and-level method: spoon flour into the measuring cup with a separate spoon, then sweep a straight edge across the top. Scooping directly can add 25–30% more weight.
For the most consistent results, use a kitchen scale. A cup measurement can vary by 15–30% depending on technique. Weighing eliminates that variable entirely.
Why the Gram Weight Varies by Ingredient
A cup is a measure of volume — how much space something occupies. Cake Flour has a specific density (mass per unit volume) that determines how many grams fit in that space. The 96 g/cup value above is calibrated for the measuring method described (spoon and level where applicable).
Different ingredients have very different densities. Compare: water (237 g/cup), honey (340 g/cup), cake flour (96 g/cup). Using a single generic "cups to grams" ratio doesn't work — the ingredient must be specified.
