Learn how to soften hardened brown sugar, whether you need it quickly or just want to salvage some brown sugar for later baking projects!
We’ve all been there. You’re all set to bake something delicious, but when you open your container of brown sugar, it’s rock hard. Or maybe you frequently find that you have difficulty keeping your brown sugar from hardening. Don’t fret, though, because there are some simple ways to salvage your brown sugar and get you back on track quickly. And there are some simple solutions designed to keep your brown sugar fresh and soft, too.
Let’s start with why brown sugar gets hardened. Unlike other kinds of sugar, brown sugar crystals are coated in molasses. When brown sugar is exposed to air, the moisture in the molasses evaporates, causing the sugar crystals to stick together.
How to Soften Brown Sugar in the Microwave
By far, the quickest way to soften hardened brown sugar is to use your microwave. Just place the brown sugar in a microwave-safe bowl. Then either place a damp paper towel on top of the bowl or fill another microwave-safe bowl with water. Place the bowl(s) in the microwave. Heat for 30 seconds at half-power and check for softness. If necessary, continue heating in 15 second intervals until the brown sugar is adequately soft.
You might need to use a fork to break up any lumps of brown sugar. Also take care not to overdo it, or you’ll melt the sugar. And you’ll want to use the sugar fairly quickly after letting it cool.
Use this method if you need your brown sugar softened quickly. Otherwise, keep scrolling for some other methods, including my favorite method for keeping brown sugar soft.
How to Soften Brown Sugar in the Oven
While the results aren’t as quick as using your microwave, your oven will also help soften brown sugar. Wrap your hardened brown sugar in aluminum foil, and place it in a 250°F oven. I recommend placing the wrapped brown sugar on a baking sheet just in case there are any spills.
Carefully check the brown sugar for softness every 5 minutes (It is hot, you know!) until adequately softened. Then let the brown sugar to cool before using in your recipe.
How to Soften Brown Sugar Using Bread or Apple Slices
This one may seem a bit odd, but just go with it. Place your hardened brown sugar in a sealable plastic bag or an airtight container. Place a slice of fresh soft bread or a few apple slices in the container with the brown sugar. Cover it tightly and leave overnight.
Check the brown sugar for softness the next morning. If necessary, seal the container again and check again after a few hours. Be sure to remove the bread or apples! (I’ve also read this works with marshmallows!)
How to Soften Brown Sugar with a Dampened Towel
Dampen a kitchen towel or thick paper towel. Wring it out well to remove as much excess water as possible. Place the brown sugar in a bowl, and cover the bowl with the dampened towel so that the opening is completely covered but the towel is not touching the brown sugar. Leave the covered bowl on your countertop overnight or until the brown sugar has softened.
If you store your brown sugar in an airtight canister, you can also cover the top surface with aluminum foil or plastic wrap,and place the dampened towel on top of the foil or plastic wrap. Close the container and leave overnight or until the brown sugar has softened.
How to Soften Brown Sugar with a Terra Cotta Disk
There are terra cotta disks made specifically for softening brown sugar, but you can also use any clean piece of terra cotta, like from a broken pot. Simply soak the terra cotta in water for about 30 minutes, dry the excess water thoroughly, and place it with your brown sugar in an airtight container. Leave the container tightly sealed overnight and check for softness the next morning.
You can leave the disk in the container to help your brown sugar retain its moisture. You’ll need to repeat the soaking process for the terra cotta every couple of months, but doing this regularly will keep your brown sugar from hardening.
How NOT to Soften Brown Sugar
You may have heard that you can use a food processor or a blender to soften hardened brown sugar. Some suggest using a box grater. Or just going crazy beating it into submission until it’s no longer a hard lump. Doing this only breaks the sugar into smaller pieces, and doesn’t add back the moisture that’s been lost.
So while you may get that brown sugar brick broken down, you’ve not actually fixed the underlying issue. Any of the other above methods I listed will work correctly to give your brown sugar new life!
How to Keep Brown Sugar Soft
I am a big believer in keeping a terra cotta disk in my brown sugar container. The other methods I described will soften hardened brown sugar, but the terra cotta method will also keep your brown sugar soft for a long time. Keep your brown sugar in an airtight container that’s not too big so you there’s as little excess air space as possible. Add one of these disks, and you’ll easily be able to keep that sugar nice and soft.
If you want to try a terra cotta disk, you’ll find many options available. I use an airtight OXO container that allows their terra cotta disk to attach to the lid. I have used it to soften rock hard brown sugar, and I also dampen the disk occasionally to keep the brown sugar soft. This is my preferred method for storing brown sugar and keeping it soft.
How to Store Brown Sugar
As you now know, the key to keeping your brown sugar soft is to help it retain its moisture. Storing brown sugar in an airtight container is usually enough to prevent hardening, but I like to take an extra step to make sure it stays soft and ready to use.
As I just described, I prefer keeping my brown sugar in an airtight container with a terra cotta disk. If you use this method, you’ll periodically need to repeat the process of dampening the terra cotta to keep your brown sugar soft.
Because air exposure is the culprit in hardening brown sugar, there’s also the option of making extra sure that your sugar storage is airtight. Try placing the sugar in a zip-top plastic bag and squeeze out the extra air. Then place that bag inside an airtight container.
It’s inevitable that brown sugar will eventually become hard if stored long enough. If you don’t use it frequently enough to avoid hardening, store it in your freezer. It will need to be in an airtight container like a zip-top bag with the excess air removed. Then just remove the container from the freezer two or three hours before you’ll need to use it.
With a little effort and planning, you can easily keep your brown sugar in ready-to-bake mode. But if that fails, you simply need to add moisture back to the brown sugar to make it useable. Luckily you have several options, whether you need to use the sugar within hours or minutes!
