How Do You Substitute Dark Brown Sugar For Light?
When substituting dark brown sugar for light, keep in mind that the flavor will be stronger and more molasses-like. To make the substitution, use the same amount of dark brown sugar as the recipe calls for light brown sugar. Bear in mind that because the sugar is darker and more heavily processed, it will be somewhat more moist than light brown sugar and have a stronger molasses flavor. Additionally, if you are concerned about the hue of your final product, keep in mind that the switch to dark brown sugar will make for a slightly darker baked good.
