Quick answer
Out of brown sugar? The most versatile swaps:
- 1
White sugar + molasses
1 cup white sugar + 2 tsp molasses (light) or 1 tbsp (dark) per 1 cup packed
- 2
White sugar alone
1 cup granulated sugar per 1 cup packed
- 3
Muscovado sugar
1 cup packed per 1 cup packed
Brown sugar is white sucrose crystals coated in molasses. That film is what a recipe is buying: it brings moisture that keeps cookies chewy, a mild acidity that reacts with baking soda, and the toffee flavor and color. So the best substitute puts molasses back, and the second best accepts losing it where it matters least.
Cookies and bars
Chewy cookies depend most on the molasses. Combine white sugar and molasses using King Arthur’s amounts: 2 teaspoons per cup for light brown, 1 tablespoon for dark. Swapping in plain white sugar gives a flatter-tasting, crisper cookie, and King Arthur notes the spread can go either way depending on the rest of the recipe. Coconut sugar is too dry to replace packed brown sugar by volume; use a third more, or weigh it.
Cakes, muffins and quick breads
These are more forgiving. In a cake leavened with baking powder, white sugar cup for cup is usually fine, especially when brown sugar is only part of the sweetener. Where the recipe uses baking soda with no other acid such as buttermilk, the molasses acidity was helping the rise; add the 2 teaspoons of molasses back rather than going without.
Sauces, glazes and rubs
In barbecue sauce, baked beans, teriyaki-style glazes and dry rubs, molasses flavor is the point, so muscovado or homemade brown sugar is the right call. In a liquid sauce, a spoonful of molasses stirred into white sugar works without mixing ahead.
When not to substitute
- Butterscotch, toffee and brown sugar fudge. The flavor comes almost entirely from the molasses; white or coconut sugar makes a different candy.
- Recipes that pack brown sugar into a crust or base, such as a crumble lid or pineapple upside-down cake, where damp sugar fuses into a glaze. Dry crystals stay sandy.
Common mistakes
- Spooning brown sugar loosely. The cup ends up short, and the cookies come out less sweet and drier.
- Using blackstrap molasses for homemade brown sugar. It is bitter and mineral; use light or dark (regular) molasses.
- Leaving molasses in clumps in a dry rub. Sticky pockets burn on the grill while the rest stays pale.
- Measuring coconut sugar as if packed. It doesn’t compress, so a level cup holds roughly a quarter less sugar.

| Substitute | Ratio | Best for | Notes |
|---|---|---|---|
| White sugar + molasses BakingCookingRaw & finishing | 1 cup white sugar + 2 tsp molasses (light) or 1 tbsp (dark) per 1 cup packed | chocolate chip cookies, gingerbread, barbecue rubs, crumb toppings | Rebuilds brown sugar from its two parts, using King Arthur's amounts. In a batter, add both separately and they blend during mixing. For a dry rub or a topping, work the molasses in with a fork until no streaks remain. |
| White sugar alone BakingCooking | 1 cup granulated sugar per 1 cup packed | cakes leavened with baking powder, muffins, recipes using a few tablespoons | The extension charts' plain swap. You lose the caramel flavor, the extra moisture and the acidity, so cookies bake up paler and crisper and may spread differently. Least noticeable where brown sugar is a small part of the sweetener. |
| Muscovado sugar BakingCookingRaw & finishing | 1 cup packed per 1 cup packed | sticky toffee pudding, spice cakes, barbecue sauce, fudge | Cane sugar that keeps its own molasses instead of having it added back, so it is just as moist and packs the same way. Light muscovado matches light brown; dark muscovado tastes stronger and more bitter than dark brown sugar. |
| Coconut sugar BakingCookingRaw & finishing | 1⅓ cups coconut sugar per 1 cup packed | oatmeal cookies, banana bread, caramel sauce, coffee | Brown, butterscotch-flavored and equally sweet, but dry and loose: a cup weighs about 154 g against 213 g for packed brown sugar, so it takes a third more by volume. Cookies come out drier and crunchier; adding 1 tsp molasses per cup brings back chew. |
| White sugar + maple syrup BakingCooking | 1 cup white sugar + 1 tbsp maple syrup per 1 cup packed | oatmeal, glazed carrots, muffins, pecan bars | The syrup returns some moisture and a soft caramel note, but not molasses' acidity or depth. A fallback when there is no molasses in the house. |

Frequently asked questions
How much molasses turns white sugar into dark brown sugar?
King Arthur uses 1 tablespoon (21 g) of molasses per cup of white sugar for dark brown and 2 teaspoons (14 g) for light. Many home recipes go as high as 2 tablespoons for dark; more molasses gives a wetter, stronger sugar.
Can light and dark brown sugar be swapped?
Yes, cup for cup. Dark brown carries more molasses, so it tastes stronger, colors the bake more and adds a little extra moisture and acid. Cookies made with dark brown may spread slightly more.
How do I soften brown sugar that has gone hard?
It hardens as the molasses dries out. Seal it in a container with a slice of bread or a damp paper towel overnight, or microwave it briefly beside a cup of water. Measure it only after it is soft again.
Why must brown sugar be packed to measure it?
Its damp crystals hold air when spooned loosely, so an unpacked cup holds noticeably less sugar. Recipes and conversion charts assume firmly packed sugar; King Arthur gives 213 g for a packed cup.
