Why measuring dark brown sugar by cup goes wrong
Dark brown sugar has more molasses than light brown — usually about double — which makes it heavier (230 g/cup packed), darker, and more caramel-forward in flavor. The extra molasses also means more moisture, which translates to chewier cookies and moister cakes than the same recipe made with light brown.
Practical tips for working with dark brown sugar
Dark brown sugar substitutes 1:1 for light brown in any recipe, and the swap is worth experimenting with in chocolate-chip cookies and gingerbread — the deeper flavor reads as 'home-baked' to most palates. The reverse swap (light for dark) is also fine but produces a lighter, less complex result.
Note from this ingredient's record: Carries more molasses than light brown — slightly heavier, noticeably moister. Swappable 1:1 with light brown but the cookie will be chewier and more caramel-forward.
