FAQ

How many grams is 1 cup of cornstarch?

1 cup of cornstarch is about 128 grams, based on a standard weight of 128 grams per US cup.

Why do gram weights for cornstarch vary between recipes?

Volume measurements depend on how the ingredient is packed. Spooned-and-leveled cornstarch weighs less than scooped. Our values use standard baking averages, so brands and techniques may differ by a few percent.

Is it better to measure cornstarch by weight or volume?

Weight. A kitchen scale removes packing errors entirely, which is why professional recipes list grams. Use this table to convert older volume-based recipes.
