In practice
Rolled (old-fashioned) oats are steamed and flattened whole groats, light and flaky, so a cup weighs only about 90 g on this page. They hold their shape in cookies, granola and porridge, giving a chewy texture, while instant or quick oats break down to a mushier consistency. If a recipe asks for rolled oats, quick oats can work in a pinch but give a softer result. Toasting oats briefly in a dry pan brings out a nuttier flavour.
How to convert cups of rolled oats to grams
