How to Measure Rolled Oats in Cups
Rolled oats are easy to measure — simply scoop into the measuring cup and level off with a straight edge. They don't compact significantly like fine powders. A cup of old-fashioned rolled oats consistently weighs about 90 grams.
The type of oat matters significantly by weight: rolled oats (90g), quick oats (93g), and steel-cut oats (160g) per cup. When following a recipe, select the right oat type in the calculator above. Use the calculator to convert any amount from cups to grams.
Pro tip: For oatmeal cookies, rolled oats are preferred for their chewy texture. Quick oats make cookies slightly softer and less chewy. Steel-cut oats are too hard for cookies without pre-cooking.
