About measuring brown sugar
Brown sugar is granulated sugar with molasses added back in, which makes it moist and clumpy. Recipes almost always mean packed brown sugar, and one US cup packed weighs about 220 grams. The molasses is what makes packing necessary: press it firmly into the cup so it holds the shape of the measure. Loosely spooned, the same cup might hold only 145 grams, a big enough gap to change how chewy your cookies turn out.
Recipes assume packed brown sugar. Press it firmly so it holds the shape of the cup.
Frequently asked questions
How many grams is 1 cup of packed brown sugar?
One US cup of firmly packed brown sugar is about 220 grams. Loosely spooned it can be as little as 145 grams, so packing matters.
Is light and dark brown sugar the same weight?
Yes, near enough. Dark brown sugar simply has more molasses, so the weight per packed cup is essentially the same at around 220 grams.
Why does my brown sugar cup vary so much?
Because of the molasses, brown sugar traps air unless pressed. A packed cup holds far more than a loose one, which is why recipes and CupsToGrams assume packed.
