Rolled oats are whole oat groats that have been steamed and flattened into flakes (quicker to prepare than steel-cut oats, which are coarsely chopped and take 20–30 minutes to cook) and chewier in texture than quick oats (which are rolled thinner for a 1–2 minute cook time). One metric cup (250 ml) of rolled oats weighs approximately 90 grams or 3.17 ounces. They are widely used in porridge, granola, baked goods such as oat cookies and crumbles, and as a breadcrumb substitute.

Oats are often sold by weight but measured by volume in baking recipes — getting the conversion right prevents dense or dry results. Measuring by weight is especially important as oats compress easily, making cup measures inconsistent.

Desiccated coconut works alongside oats in granola, flapjacks, and crumble toppings, adding sweetness and a fine crunch where oats give chew. They are close in weight (88 g vs 90 g per cup), so weigh rather than scoop when the ratio matters. See our Desiccated Coconut converter.
