Corn Flakes — Grams in Cups

About corn flakes measurements
Corn flakes are almost all air: at a reference density near 0.1 g/ml (FAO density database), a US cup of whole flakes weighs only about 24 g, near a single serving. Crush them and the same cup packs two to four times heavier, so a crushed-cornflake crust needs far more cereal than the loose cup suggests. Weigh them when it counts.

A note on cooking ingredients measurements
