Measuring 450g of Dark Brown Sugar in the Kitchen

Because 1 US Customary Cup (236.6 mL) of dark brown sugar weighs 213g when measured firmly packed, 450 Grams (450g) translates to 2.11 US cups (2 ⅛ cups). By contrast, using the unpacked / loose measure (150g/cup — a 63g per-cup shift), 450g occupies 3 cups (3.00 cups).

Without a kitchen scale, measure 2 ⅛ cups (33.8 tablespoons total) using firmly packed technique. Pack firmly into the measuring cup to press out all air pockets. Dark brown sugar contains approximately 6.5% molasses, making it denser and stickier than light brown sugar.
