How to store brown sugar long-term?

  • Place brown sugar in a tightly sealed container, such as an airtight canister or container.
  • Place it in a resealable plastic bag in its original packaging.
  • It should be kept in a cool, dry place, such as the pantry, cupboard, or kitchen cabinet.
  • Keep it tightly closed and away from strong-smelling foods. Sugar granules absorb odors from nearby food, altering their smell and flavor. It is not a sign of spoilage, but the brown sugar will no longer be a pleasant ingredient!
  • Place it away from any heat sources, such as a microwave oven, stove, heaters, or radiators.
  • Brown sugar should not be refrigerated. It will harden as a result of the cold temperature.


  • sugar granules
  • 1 tbsp unsulphured molasses for light brown sugar
  • 2 to 3 tbsp dark brown sugar


  • Using an electric mixer, combine the sugar and molasses in a large mixing bowl until completely combined. Use immediately or store in an airtight container. To keep brown sugar from hardening, use a brown sugar saver.
  • If it becomes too hard, add the soaked brown sugar saver to soften it. You can also add a slice of bread for a few hours to soften it.

How long does brown sugar last?

Brown sugar has an 18-month shelf life. Brown sugar contains more moisture than white sugar, which reduces the shelf life of brown sugar when stored in its original packaging in the pantry. Brown sugar, on the other hand, has an indefinite shelf life when stored in an airtight container with an oxygen absorber.

What are some methods for reviving hard brown sugar?

  • In an oven-safe pan, heat the brown sugar in a 250°F oven. Keep an eye on it and measure the amount you require as soon as it becomes soft. As it cools, it will harden.
  • Cover a damp paper towel with brown sugar in a microwave-safe container. Microwave on high for 30 seconds. Repeat the process until the dough is soft. As it cools, it will harden.
  • Place brown sugar in a plastic container and cover with a small piece of plastic wrap or foil. 
  • Cover the plastic/foil with a damp paper towel or napkin. Close the lid tightly. Remove the paper towel after a few days. Keep the container tightly closed.
  • In an airtight container, layer a few apple slices or a slice of bread with the brown sugar. Remove after the sugar has softened, which should take a day or two.
  • In a food processor, grind the hardened chunks. Take care not to damage your food processor.
  • Soak a piece of clay for 30 minutes in water. Make sure the piece isn’t dripping wet. Seal the clay in the container with the sugar. 
  • You should have softened sugar again in a few days. You can leave the clay in for as long as you want. You can even buy cute clay bears made specifically for this purpose.

Is it possible for brown sugar to spoil?

No, brown sugar, like other types of sugar, can be stored indefinitely as long as it is not exposed to air or moisture and bugs are kept at bay.

After opening, some manufacturers include a two-year best-before date. Brown sugar will not go rancid after two years, but the taste and texture will change slightly. Brown sugar can only spoil if it becomes contaminated due to improper storage.

How do you restore hardened brown sugar?

  • With a fork, crush the hardened brown sugar. It takes time, so only do it when you need a small portion.
  • Place the hard lumps in a plastic bag and mash them with a rolling pin.
  • Using a food processor or a coffee grinder, grind the brown sugar.
  • In a microwave-safe bowl, combine the brown sugar and the butter. Place a moist paper towel on top and microwave for one to two minutes. If you don’t use it all, store any leftover sugar in a separate container. Try it in recipes or in your coffee. This warmed-up sugar will only be good for one to two weeks.
  • If you have a few hours before you need your brown sugar, put a slice of bread, a few marshmallows, a bit of orange peel, or an apple wedge in the sugar container. Allow it to sit in the sealed container for a few hours. The molasses will absorb some moisture, causing the brown sugar to soften once more.
