Here are a few tips for keeping brown sugar soft and fluffy!
Tips to keep brown sugar from clumping
Keep brown sugar in an air tight container
A terracotta disc is great for keeping brown sugar moist. I have had mine for years and have never had clumpy brown sugar. Every so often I just get the terracotta disk wet (let the water completely absorb into the terracotta before placing in the sugar) We sell the brown sugar bear at Sweet Baking Supply.
A slice of bread placed with the brown sugar for a couple of days can make the sugar moist again.
Throw a few marshmallows in with your brown sugar and they too will help keep the sugar moist.
Toss a couple of saltine crackers in with the brown sugar
Need a quick fix so you can bake right away?
Place the brown sugar in the microwave along with a small bowl of water sitting beside it.Microwave at 30 seconds intervals until soft. Watch closely so that you don’t melt it.
The brown sugar can also be placed in a baking pan or wrapped in aluminum foil and set in a 250° F oven for 5 minutes or until soft.
