What is brown sugar?

It might be helpful to start with defining what brown sugar is first, because that will easily explain why there's a difference.

This explains why brown sugar is softer and moister with that distinct caramel flavor and gives baked goods like Cowboy Cookies their chew. It's also why adding molasses to white sugar is a popular brown sugar substitute.

Brown sugar doesn't keep as well in storage as granulated white sugar due to that added moisture as well. It will eventually evaporate, leaving the sugar hard. Not to worry though, because you just need the secrets of how to soften brown sugar when you're in a pinch and prevent that from happening by buying a brown sugar bear.
