Homemade Light Brown Sugar Recipe
Store-bought light brown sugar is just granulated sugar with molasses added back in, so mixing the two yourself in the exact same 1-to-16 ratio gives identical flavor and texture without a grocery run, and you control exactly how moist and clumpy it turns out.

Instructions
- 1Add the granulated sugar and molasses to a medium bowl or the bowl of a food processor.
- 2If mixing by hand, use a fork or rubber spatula to press and fold the molasses into the sugar, scraping the bottom and sides often, until no streaks of molasses remain and the mixture looks uniformly golden, about 3 to 5 minutes.
- 3If using a food processor, pulse in 10-second bursts, scraping down the sides between pulses, until fully combined, about 30 to 45 seconds total.
- 4Break up any remaining clumps with the back of a spoon. The sugar should look and feel like store-bought light brown sugar, moist enough to hold together when pressed between your fingers.
- 5Transfer to an airtight container, pressing out air pockets, and use immediately or store for later.
Tips & variations
- For dark brown sugar instead of light, double the molasses to 2 tablespoons per cup of sugar.
- Blackstrap molasses gives a stronger, more bitter edge than regular (unsulfured) molasses; regular molasses is the better match for light brown sugar's mild flavor.
- Scale the recipe up freely as long as the ratio stays 1 tablespoon molasses per 1 cup granulated sugar.
- If a recipe calls for packed brown sugar, press this mixture firmly into the measuring cup the same way you would with the store-bought kind.
Storage & reheating
Store in an airtight container at room temperature indefinitely. If it hardens, add a slice of bread, a few marshmallows, or a damp paper towel to the container for a few hours to soften it, or microwave in 10-second bursts with a damp paper towel draped over the container.
Tips from the Tulo kitchen
- A fork works better than a whisk for the initial mixing since molasses tends to gum up whisk wires.
- Weighing the sugar and molasses on a kitchen scale gives a more consistent result than measuring molasses by volume, since it clings to spoons and cups.
FAQ
What's the difference between light and dark brown sugar?
Only the amount of molasses. Light brown sugar has about 3.5% molasses by weight (roughly 1 tablespoon per cup of sugar), while dark brown sugar has closer to 6.5% (about 2 tablespoons per cup), giving it a deeper color and stronger, slightly bitter-sweet flavor.
Can I substitute homemade brown sugar 1:1 in baking recipes?
Yes. Since it's made to match commercial brown sugar's molasses ratio, it measures and behaves the same in cookies, cakes, and sauces, including how it packs into a measuring cup.
Why does brown sugar harden in the pantry?
The molasses in brown sugar is hygroscopic, meaning it draws in moisture, and when sugar is exposed to dry air that moisture evaporates, letting the sugar crystals fuse together into a hard block.
Can I make this with honey or maple syrup instead of molasses?
No, those don't recreate the same flavor or texture. Molasses has a distinct bitterness and thickness that honey and maple syrup lack, and using them instead will leave the sugar too wet and change the taste noticeably.
