Measuring 1 Tablespoon of Dark Brown Sugar in the Kitchen

Measured firmly packed at a verified bulk density of 213g per US cup, 1 tablespoon of dark brown sugar weighs 13.3 grams (0.47 ounces). Measured using the unpacked / loose method (150g/cup), that same 1 tbsp holds 9.4g — a 3.9g difference in your mixing bowl.

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.
