Substitute for brown-sugar in baking
Quick answer
The most reliable substitute is white granulated sugar plus unsulfured molasses: mix 1 cup (200g) white sugar with 1 tbsp molasses for light brown sugar, or 2 tbsp molasses for dark. This replicates both the moisture content and the flavor that brown sugar provides in baked goods.

| Rank | Substitute | Ratio (replaces 1 cup brown-sugar) | Notes |
|---|---|---|---|
| #1 | White granulated sugar plus unsulfured molasses | 1 cup (200g) white sugar + 1 tbsp molasses (light brown) or 2 tbsp molasses (dark brown) | This is literally how commercial brown sugar is made. The molasses adds back the hygroscopic moisture and caramel-bitter depth that brown sugar provides. Mix thoroughly until no streaks remain before adding to your batter or dough. Results are functionally identical to store-bought in cookies, cakes, and quick breads. |
| #2 | Coconut sugar | 1:1 by weight (substitute equal grams) | Coconut sugar has comparable moisture-binding behavior and a similar caramel-like flavor. Cookies spread slightly less and bake up a touch drier than with brown sugar; the flavor is nuttier and less molasses-forward. Works well in cookies and muffins. Not ideal in recipes where a pronounced molasses flavor is central, like gingerbread or Boston baked beans. |
| #3 | White granulated sugar | 1:1 by volume or weight | Works in a pinch but produces noticeably different results. Baked goods will be crisper, drier, and paler because white sugar lacks the moisture-retaining molasses. Cookies spread more and lose chewy texture. Use this only when you need the sweetness and have no other option; accept that the texture and flavor will differ. |
| #4 | Muscovado sugar | 1:1 by weight | Muscovado is an unrefined cane sugar with high natural molasses content — higher than standard brown sugar — so it produces a more intense, slightly bitter, toffee-like flavor. Texture in the finished bake is moist and dense. Works very well in chocolate baked goods, spiced cakes, and anything where a bold molasses note is acceptable. Harder to find than other options. |
Why baking is different
Brown sugar's molasses content makes it hygroscopic — it attracts and retains moisture in the finished bake. This is what gives brown sugar cookies their characteristic chew and keeps quick breads moist longer after baking. Brown sugar also contributes to Maillard browning and adds a faint acidity that can react with baking soda, giving slightly more lift; a substitute that lacks this acidity may produce marginally less rise.
Common mistakes
The most common error is substituting white sugar 1:1 without adding molasses and expecting the same result — the bake will be noticeably drier and crispier, not just slightly different. A second frequent mistake with the DIY white sugar plus molasses method is under-mixing: streaks of unmixed molasses create uneven texture and dark spots in the crumb. Measure molasses by weight when precision matters, since it clings to spoons and measuring cups and is easy to under- or over-pour by volume.
Brown sugar’s role in baking goes beyond simple sweetness. The molasses it contains holds onto water molecules through the baking process, which is why brown sugar cookies stay softer for days while an identical cookie made with white sugar turns crisp as it cools. Any substitute that replicates this behavior — either by containing molasses directly (muscovado, coconut sugar) or by adding it back (the white sugar plus molasses method) — will produce results close enough to be indistinguishable to most people.
The DIY white sugar plus molasses blend is the substitute most consistently recommended by King Arthur Baking, America’s Test Kitchen, and Serious Eats because it controls exactly how much molasses goes in. Light and dark brown sugars differ mainly in molasses concentration — about 3.5% for light, up to 6.5% for dark — so the ratio matters if your recipe depends on a specific depth of flavor. When in doubt, err toward less molasses rather than more; too much makes dough sticky and produces an overpowering bitterness in the finished bake.
Frequently asked questions
- Can I use honey or maple syrup instead of brown sugar in baking?
- You can, but it requires recipe adjustments beyond a simple swap. Both are liquid sweeteners (roughly 20% water), so using them 1:1 by volume will throw off the wet-to-dry ratio of your recipe. Most baking authorities recommend reducing other liquids by about 3 tbsp per 1 cup of honey or maple syrup used, and reducing oven temperature by 25°F to prevent over-browning. These are workable substitutes but not straightforward ones.
- Does the substitution ratio change if the recipe calls for packed brown sugar?
- Yes. When a recipe specifies packed brown sugar, it means the sugar is compressed into the measuring cup — about 200g per cup for light brown sugar. If you measure your substitute loosely, you'll under-measure. Always weigh your substitute in grams when the original recipe specifies packed: 1 cup packed light brown sugar = 200g; 1 cup packed dark brown sugar = 220g.
- Will coconut sugar make my baked goods taste like coconut?
- No. Coconut sugar does not taste like coconut — it has a mild caramel and toffee flavor closer to brown sugar than to coconut flesh or coconut milk. Most people cannot identify it as coconut sugar in a finished bake.
