Have you ever wanted to bake some chocolate cookies at 2am, then realize that your brown sugar is hard and unusable? It has happened to me, and I almost broke the hearts of friends who were waiting for them. But then I figured there is probably a way to fix the situation, and there is.
The reason why the sugar hardens is because it loses its moisture, so you have to put it back in. There are two easy methods that I will explain below
place a bowl of water in the microwave next to a bowl or plate of brown sugar. first microwave it for 1 minute, then at 30 second intervals until it is soft
Stove top method:
boil a pot of water and hold the sugar over the pot so it absorbs the steam.
When your sugar begins to soften, crumble it with your fingers and pack it into your measuring cup.
So, no more running to the store when you have your oven pre-heating!
