Why does brown sugar get hard?

Brown sugar is coated in molasses. When the sugar is fresh, the molasses coating allows the sugar crystals to move easily over each other and the sugar will be soft and easy to work with.

When brown sugar is exposed to air, the moisture in the molasses starts to evaporate. This causes the particles of sugar to stick to each other as the coating dries out.

Once this happens, the brown sugar will harden into a solid mass of sugar.

Softening brown sugar with bread

Add a slice of bread to the container of brown sugar. Within about 8 hours (longer if it is really hard), the brown sugar will become soft and ready to use again.bread and brown sugar

Why does the bread work to soften brown sugar?   Bread contains moisture that will evaporate if it is exposed to air.  However, if the only air is in a sealed container with dried out brown sugar, the water vapor molecules will stick to the sugar crystals.

This causes them to be surrounded by a thin layer of water, so the sugar softens and crumbles.

It is not just bread that will help to add moisture back to hardened brown sugar. You can also use apple or pear slices to do the same thing.

This brown sugar softening trick takes a little while to work but it does the job, every time. It can take 8 to 24 hours for this trick to work.

One thing may happen when use this method to soften the brown sugar.  The top layer of sugar may get lighter in color since the bread will absorb some of the molasses coating. It is still fine to use but won’t have quite the same rich flavor.

Using the microwave to soften brown sugar

The quickest way to soften brown sugar that has gone rock-hard is to use your microwave. Place the hard brown sugar in a microwave safe bowl and place a damp paper towel over the top of the bowl.Damp tea towel on a bowl of brown sugar in the microwave will soften it

Heat on 30 second intervals at a half power setting. Check the softness between each heating interval. When it is almost soft, reduce the cooking time to 15 seconds until the brown sugar is soft enough to use.

It may be necessary to use a fork now an then to break up any lumps in the brown sugar. 

Be careful not to heat it too long, or the sugar will start to melt. It’s also important to use the sugar fairly quickly after letting it cool so that it doesn’t get hard again.

This method is perfect for those times that you want your brown sugar softened very quickly.

Seal tightly and check in a couple of days to make sure that the sugar has absorbed the moisture and is soft again.

Work the sugar with a knife to remove any clumps and tightly reseal the container. The sugar should remain soft.

Take a kitchen towel and dampen it well. Wring out the towel as that you have removed as much of the excess water as possible.

This also works if you store your brown sugar in canisters with air tight lids. In this case, cover the top surface of the container with plastic wrap and the add the dampened towel over the top of the wrap. Leave it over night to soften.

These brown sugar disks will also work to keep dried fruit, popcorn, marshmallows and spices fresh.

If you don’t have one of these disks, a piece of terra cotta from a broken plant pot (sterilized and cleaned before use) will work. I broke a small terra cotta pot and polished the edges with a pumice stone, then soaked it. It works great!pieces of terra cotta and a pumice stone

Soak the terra cotta disk or piece in water for about 30 minutes, dry off the excess water , and place it with your brown sugar in an airtight container.

All of these tricks will help with softening brown sugar that has gone hard. How do you keep this from happening in the first place?

Air is what causes the sweet molasses-coated crystals to dry out, so airtight containers are what’s needed for effective storage.

The terra cotta disks mentioned above will help to keep your sugar soft for a few months. Just leave the disk in the container to help keep your brown sugar soft. If you do this, you will need to repeat the soaking process in a few months. 

Keeping carrot peels, or saltine crackers in the brown sugar container also helps to keep it from hardening.

For long term storage, the use a double storage airtight environment. Place the brown sugar in a zip top bag. Roll up the bag to squeeze out any excess air and seal the lock bag of brown sugar inside an air tight canister

Place this bag into a container with a tight lid and it will keep the sugar moist for -12 months.

Remember that the quality of brown sugar is best when consumed within 6 months of purchase and opening. Don’t store brown sugar in the fridge.

Freezing brown sugar

With the worry of having  your brown sugar going hard, you may not be inclined to take advantage of sales of it at the store. Don’t pass those sales by!

Brown sugar can be frozen! Double bagging it will help to keep ice crystals away from the sugar.

After freezing, use a fork to separate clumps in the sugar before using it. If any ice crystals have formed, stir often as it thaws to make sure the sugar is not affected by the excess moisture.

Thaw frozen sugar and use a fork to separate clumps before using. If ice crystals form after long freezer storage, frequently stir the sugar as it thaws to prevent the sugar from being affected by pockets of moisture.

Hi! Being Christmas Day i'm guessing you won't be able to reply but I have an embarrassing problem! I softened my full bag of rock hard brown sugar IN a bowl of water on high in my microwave needing it to make soft ginger cookies. The sugar is now in in liquid form! Can I use this as a cup of brown sugar in its current liquid state or do I wait for it to harden again?!

Urgh - no time to read the entire suggestions and my microwave isn't large enough to put two bowls in (one with sugar and one with water) thus I combilned the two.

If you added the brown sugar to the bowl of water, you changed the product to more of a syrup. It won't turn into brown sugar again.

Thank you for sharing these genius and simple ways to rescue my cookie making since all of the stores are closed now. Most suggestions that appeared in my search involved a microwave, which I don't use. Your comprehensive list gave me many options I really can use! Thanks so much!
