Common questions
How many grams is 1 cup of packed brown sugar?
One US cup of firmly packed brown sugar weighs about 220 grams — heavier than granulated sugar because the molasses coating makes it denser.
Do I pack brown sugar the same as granulated sugar?
No. Recipes assume brown sugar is packed down into the cup, while granulated sugar and flour are usually spooned in loosely and levelled.
