About Quick Oats
Quick oats are rolled oats that have been cut into smaller pieces before rolling, producing a thinner, finer flake that cooks and softens faster than standard rolled oats. In baking, this finer texture blends more smoothly into batter, giving a less chewy, more uniform crumb than rolled oats provide.
Why the Weight Per Cup Varies
Quick oats weigh slightly less per cup than rolled oats, 85g versus 90g, because their thinner, more finely cut flakes trap marginally more air between them. The difference is small, but worth accounting for in recipes where the exact amount of oats affects texture.
Names in Different Countries
"Quick oats" or "quick-cooking oats" (US/AU). Distinct from "instant" oatmeal sachets, which are pre-cooked and often contain added sugar or flavourings, making them unsuitable for baking.
Common Recipe Uses
Oatmeal cookies where a smoother texture is preferred, quick breads, muffins, meatloaf or burger binders, porridge.
Substitutions
Rolled oats substitute 1:1 by weight, giving a chewier, more textured result. Avoid instant oatmeal sachets, which contain added sugar and flavourings.
