About Light Brown Sugar
White sugar with about 3.5% molasses added back in, giving a pale caramel colour, moist texture, and gentle toffee flavour, adding chewiness and moisture that white sugar alone cannot.
Why the Weight Per Cup Varies
Brown sugar is almost always measured packed — pressed firmly into the cup — giving 213g per cup. Loosely packed, it weighs only 150–160g, which is why recipes assume "packed" unless stated otherwise.
Names in Different Countries
Known consistently as light brown sugar; UK product sometimes labelled "light soft brown sugar."
Common Recipe Uses
Chocolate chip cookies, brownies, banana bread, crumbles.
Substitutions
White sugar substitutes 1:1 but loses moisture and flavour. Make your own: 1 cup white sugar + 1 tbsp molasses, mixed thoroughly.
