Single-conversion pages for oat flour
Working with oat flour
Oat Flour sits in the flours & starches group, where the ingredient is light and airy, so a cup contains a lot of trapped air and the weight swings easily with handling. Home-ground oat flour is fluffier than commercial flour. Weigh it if you blend your own oats.
If you are converting a whole recipe rather than a single line, the Recipe to Metric converter matches every ingredient to its own density in one pass, and the Recipe Scaler resizes the batch first so you only convert once.
