Oat Flour Grams to Cups
One cup of oat flour weighs 104 grams — lighter than wheat flour because it is simply ground oats, soft and a little fluffy. You can make it at home by blitzing rolled oats in a blender.
Oat flour is naturally gluten-free (use certified oats if that matters) and adds a tender, slightly sweet crumb. It does not behave like wheat flour one-for-one — without gluten it needs a binder or a blend — so weigh it and follow an oat-flour recipe. About 1¼ cups of rolled oats grinds down to 1 cup of oat flour.
