The short answer? Absolutely, yes. You can swap light for dark brown sugar almost any time. It’s not a baking crime; it’s a happy accident.
Think of them as cousins, not strangers. They’re made from the exact same stuff: white sugar and molasses. Dark brown sugar just has a lot more molasses mixed in.
That’s it. That’s the whole secret. So relax, your kitchen isn’t broken.
What’s the Actual Difference?
Let’s get into the tiny, delicious details. Light brown sugar has about 3.5% molasses. Dark brown sugar? It’s rocking about 6.5%. It’s basically a molasses double-shot.
More molasses means two things: flavor and moisture. Dark brown sugar tastes richer, almost like a deep toffee or caramel. Light brown sugar is more subtle, like a gentle hug.
Moisture-wise, dark brown is stickier and wetter. Light brown is a bit drier and fluffier. Does this matter? Only if you’re a very serious baker.
