How to measure Brown sugar by volume
- Spoon brown sugar into the cup in layers, pressing each layer down firmly.
- It is packed correctly when the sugar holds the cup’s shape as it comes out.
- Level the top after the final press.
Why the weight varies
Brown sugar is measured firmly packed. Loosely scooped it can weigh 20–40 g less per cup.
The molasses in brown sugar traps air, which is why packing matters. If your brown sugar has hardened, soften it before measuring — chiselled lumps pack unevenly and weigh unpredictably.
Which value we publish, and why
We publish 220 g per US cup packed (USDA FoodData Central); King Arthur lists 213 g.
