Anything that gets in the way of whipping up a batch of chewy chocolate chip cookies is definitely something to watch out for in the future. Fossilized brown sugar has likely interfered with baking ventures more times than you can count! Thankfully, there are several ways to prevent brown sugar from turning into a rock (though, if it has hardened, here’s the best way to soften brown sugar). Here’s how to keep brown sugar soft for all of your baking goals.

Air-Tight Container

One of the best ways to keep brown sugar soft is also the simplest. Use a food-safe container with a tight-fitting lid or a resealable plastic bag to help keep brown sugar from losing moisture. These containers prevent the brown sugar from being exposed to air and subsequently drying out.

Terra Cotta Brown Sugar Savers

Another method you can use to keep brown sugar soft is to use a terra cotta brown sugar saver. You can purchase these small but mighty tools at almost any baking supply store or order them online. Just soak it in water and seal it in with the brown sugar to help keep it soft. As explained in this article about brown sugar savers, this tool works by transferring the moisture it absorbs from water into the sugar, making sure it stays soft.


Dense, fluffy marshmallows are great for more than just s’mores. Since marshmallows contain quite a bit of moisture, you can use them to help keep brown sugar soft. All you have to do is add a couple marshmallows to a sealed bag or container of brown sugar to keep it from drying out.


Storing your brown sugar in a sealed bag in the freezer can help lock in moisture, some cooks say. Just be sure to let it come to room temperature at least 15 minutes before you plan to use it.
