Soften Hardened Brown Sugar
All types of brown sugar can harden if not properly stored in an airtight container. It can become virtually unusable, but don’t throw it away. If you’ve discovered your brown sugar is rock hard, take the necessary steps to soften it. It’s easy to soften a container of hardened brown sugar immediately or overnight. Hard and once unusable brown sugar will become as soft as it was when freshly homemade.
Simply place a piece of fresh bread on top of the hardened mass. Seal the container, and in the morning the bread will be hard and stale, and your homemade brown sugar will be soft, fresh, and once again useable.
For a quick fix, place an open microwave-safe container of brown sugar in the microwave next to an open cup of cool water. Microwave the water and brown sugar on high for about two minutes. This will immediately soften it, and when it cools you can use it in a recipe.
