For most everyday baking, it’s a perfect substitute. Think chocolate chip cookies, banana bread, or snickerdoodles. The difference is almost invisible.
Honestly, plenty of home bakers (and even pros) don’t even stock dark brown sugar. They just use light and call it a day. Your cookies will still be chewy and delicious.
Will they be a tiny bit less “deep”? Maybe. Will anyone complain? Only if they’re a robot with a flavor meter. You’re safe here.
When You Should Stick to Dark (If You Can)
Alright, now for the “but” moment. There are a few special cases. Molasses-forward recipes like gingerbread, molasses crinkles, or dark rum cakes really want that dark sugar.
Here, the dark brown sugar is the star of the show. It’s not just a supporting actor; it’s the headliner. Using light brown here is like wearing sandals in a snowstorm—it’s just not right.
Also, if you’re making a wet rub or a barbecue sauce? Go dark. The extra molasses adds that sticky, tangy, “I’ve been cooking all day” vibe. Light brown will taste a little… flat.
