Why Brown sugar (packed) Has This Density

Brown sugar (packed) is granulated sugar coated in molasses, which makes the crystals stick together instead of settling loosely. It's meant to be measured packed, so its "true" density only shows up when it's pressed firmly into the cup.

A cup of brown sugar (packed) is about 1.8× heavier than a cup of all-purpose flour (125g/cup), even though both fill the same 1-cup measuring cup.

Common mistake: Measuring it loose and spooned like granulated sugar, which under-fills the cup and throws off the ratio in the recipe.

Measuring Tips for Brown sugar (packed)

Pack brown sugar (packed) firmly into the measuring cup with the back of a spoon until it holds the shape of the cup when turned out. This is one of the few common ingredients where packing is correct, not a mistake.
