I can’t tell you how many times I’ve gone to bake something and realize that I don’t have any brown sugar left. Luckily, there is an easy solution that problem – make your own brown sugar! You only need two ingredients – molasses and granulated sugar. Not only does homemade brown sugar come out fluffier and softer than store bought brown sugar – it has a fantastic taste and beautiful color to it.
For light brown sugar = 1 cup of granulated sugar to every 1 tablespoon of molasses
For dark brown sugar = 1 cup of granulated sugar to every 2 tablespoons of molasses
Combine the sugar and molasses with an electric mixer, starting on low speed, then slowly increasing the speed to high. Mix the sugar for 5-8 minutes, or until all the molasses balls are incorporated into the sugar. Store in an airtight container.
