How to soften sugar when hardened?

Just because the texture of sugar has changed and become hard, does not mean that it has gone bad. It can be restored.

How to Soften White Sugar:
White sugar will become hard if it absorbs moisture, so to soften it again you can place it in a 150 degree oven for 15 minutes then break it up with a spoon, turn the oven off and leave it in the oven for another hour or two.

How to Soften Brown Sugar:
Brown sugar will become hard when it dries out and looses it’s moisture, so to soften it you can add a slice of fresh bread to the bag for a day or two or a damp paper towel separated from the sugar by plastic wrap. You can also use an organic (or washed well & dried) orange peel to place in the container, the natural oils from the orange will soften the sugar. The paper towel or orange peel method will soften brown sugar within several hours while the bread will soften brown sugar in a few days (1-2), but is the preferred method.
If you are in a big hurry, you can cover a bowl of brown sugar with a damp paper towel and microwave for about 20 seconds – but be careful as a few too many seconds can produce a bowl of goo!

Whichever method you choose to soften your brown sugar, be sure to remove the bread/towel/peel from the bag once the brown sugar is soft or you will be inviting mold into your sugar.
These methods can be repeated if the sugar again hardens, but proper storage will prevent the need.

How to Soften Powdered Sugar:
Powdered sugar will begin to form lumps when it has been around too long, this is because of the corn starch that is in the sugar and there is really nothing you can do except break up the lumps.

How to Soften Raw Sugar:
Raw sugar will become hard if it absorbs moisture, so to soften it again you can place it in on a tray in a 150 degree oven for 15- 30 minutes then break it up with a spoon. Be careful not to overheat the sugar or it will burn.
