Brown sugar is a versatile sweetener that adds moisture and a rich caramel flavor to countless dessert recipes. It’s a key ingredient in some of my favorite recipes, like our gooey Deep Dish Chocolate Chip Cookie, flavorful Bananas Foster, crunchy Butter Pecan Granola, and moist Mini Spice Cake.

How To Make Brown Sugar

  • Measure the Ingredients: For light brown sugar, combine 1 cup of granulated sugar with 1 tablespoon of molasses (similar to treacle in the UK). For dark brown sugar, add an extra tablespoon of molasses.
  • Mix Thoroughly: Place the sugar in a medium bowl and drizzle the molasses over it. Using a fork, rubber spatula, or your fingers, mix the molasses into the sugar until evenly combined.

Note: If molasses clumps form, press them against the side of the bowl with a spatula or use your fingertips to break them up. Keep mixing until the sugar is smooth and evenly blended.

Expert Tips

  • Adjusting the Molasses: For light brown sugar, use 1 tablespoon of molasses per cup of white sugar. If you prefer dark brown sugar, increase the molasses to 2 tablespoons per cup.
  • Molasses Substitutes: If you’re out of molasses, substitute with 1 tablespoon of pure maple syrup, golden syrup, or agave nectar per cup of granulated sugar. While the flavor will differ slightly, the texture and moisture will remain similar. These alternatives are great in a pinch!

    Love this reminder of how easy it is to make pantry staples with the pantry staples I already have ๐Ÿ˜ƒ Also, that was great idea from Ed about making the dark corn syrup in a similar fashion.

    It could be my imagination, but this brown sugar seems more fragrant and flavorful than the stuff I get in the grocery store. Maybe it’s because I used blackstrap molasses. Whatever it is, I’m looking forward to using it in an ODK chocolate cake and the pancake syrup this weekend ๐Ÿคค

  2. Ed says:

    This works very well. If you have light brown sugar but need dark brown, just add the 1 tbsp per cup to the light brown. You can use the same approach if you need dark corn syrup and only have light: 1 part molasses to 3 parts light corn syrup. This cuts down on pantry staples too. I make your pecan pie with 1 tbsp molasses and 3 tbsp light corn syrup.
    Love this site (and the cookbook which does have recipes not on here).

      Thank you, Ed. I’m so glad you are enjoying the recipes. Thank you for your feedback.
