Why measuring oat flour by cup goes wrong
Oat flour is rolled oats ground fine. It tastes mildly sweet, has no gluten, and tends to give baked goods a tender, slightly cakey crumb. A cup weighs ~92 grams. If you grind your own from rolled oats, the texture varies based on how long you blend — finer flour packs tighter and weighs a few grams more per cup.
Practical tips for working with oat flour
Substitute up to a third of the wheat flour in a quick bread or pancake recipe with oat flour for added chew and a softer crumb. Going higher than that without adding more egg or a binder produces a crumbly result. Sifted oat flour also makes an excellent gluten-free dredge for fried chicken — it's nuttier than rice flour and crisps faster than cornstarch.
Note from this ingredient's record: Lighter than wheat flour and absorbs liquid differently. Best stored sealed — its high natural oil content turns it rancid faster than wheat flour.
