You’re telling everyone at work about the new brown sugar pound cake recipe you discovered — best ever! — and promise to bake it tonight and bring it in tomorrow. But you go to make the cake and whoops! No brown sugar. DRAT (or words to that effect). “What can I substitute for brown sugar?”
We’ve all been there, right? Super-enthused, ready to bake — and missing one everyday basic ingredient. Butter. Milk. Brown sugar.
Don’t despair. Thankfully, at least in the case of brown sugar, there are many ways to get around this irritating conundrum (besides making an emergency trip to the supermarket).
In order to choose a good substitute for this key ingredient, we first need to understand what it is.
What is brown sugar?
Back in the day, brown sugar was sugar cane juice that was partially evaporated, then run through a centrifuge to remove some (but not all) of the natural molasses that gives it its color. Once the brown sugar had been “harvested,” the remaining sugar was further processed to become white granulated sugar.
Today, the light brown and dark brown sugar you commonly buy is white granulated sugar with molasses added back in — up to 10% molasses, by weight.
Can I substitute light brown sugar for dark brown sugar, and vice versa?
Yes. The only difference will be in color and taste. Just to state the obvious, light brown sugar makes baked goods with lighter color and milder flavor; dark brown, darker colored baked goods with more assertive (but still very mild) molasses flavor.
Structurally, the two sugars function the same. One might argue that dark brown sugar, with its greater percentage of added molasses (and thus liquid) might make cookies spread more; but if that happens, it’s so minimal that you or I typically wouldn’t notice the difference between cookies made with light or dark brown sugar.
What if I don’t have either light or dark brown sugar?
If you have molasses and granulated white sugar, you can make your own substitute. For every cup of brown sugar called for in your recipe, substitute 1 cup (198g) white granulated sugar and 2 teaspoons (14g) molasses for light brown sugar; or 1 cup (198g) white granulated sugar and 1 tablespoon (21g) molasses for dark brown sugar. There’s no need to mix the molasses into the sugar; simply add both to your recipe at the same time.
Note that brown sugar (213g per cup) weighs slightly more than white sugar, but don't worry about that. Once you add the molasses, the weight of your DIY brown sugarwill be very closeto the weight of "real" brown sugar, andyour recipe won't need any further adjustments.
In a pinch you may be able to substitute white granulated sugar for brown sugar, but to do so is to tempt the culinary gods.
Can I simply swap white sugar for brown sugar?
Besides adding wonderful flavor and color to baked goods, brown sugar is acidic and lowers pH — which is why you’ll often find recipes with brown sugar relying on baking sodafor their leavening. Low pH brown sugar + high pH baking soda = the reaction of leavening.
If you use white sugar in place of brown, your cookies may spread less (or more, depending on the other ingredients in the recipe). Cake and muffins may not rise as well; or they may rise just fine, depending on their mixing technique (stir-together or creaming). In short, using white granulated sugar in place of brown sugar will produce unpredictable results; sometimes the swap works just fine, sometimes not so well.
Want to sweeten your odds for success?
In recipes calling for baking powder (no baking soda), and where the amount of brown sugar is less than that of white sugar, you can probably get away with the substitution.
Take our Cinnamon-Streusel Coffeecake, for instance. The cake itself calls for 1 1/2 cups (298g) granulated sugar and 1/3 cup (71g) brown sugar; it also uses baking powder as leavening. The small proportion of brown sugarhas no impact on the cake's structure, thus allowing you to substitute granulated sugar.
The cake's filling calls for a cup of brown sugar, plus cinnamon and cocoa powder; no granulated sugar at all. Substituting white sugar here is OK structure-wise (filling doesn't really have any structure); but you'll lose the wonderful caramelized flavor of brown sugar, and the coffeecake will be that much the poorer for its absence. After all, at some point you do have to pay the piper.
Can I substitute a more natural brown sugar?
Peruse the sugar shelves at your supermarket; you’ll see the familiar light and dark brown sugars, but around the periphery you might also spot packages labeled Sugar in the Raw, turbinado sugar, or perhaps even Demerara or muscovado sugar. These “natural” brown sugars, ranging in color from light hazelnut to deep-dark mahogany, are manufactured by centrifuging partially evaporated sugar cane juice, rather than adding molasses to white granulated sugar.
Unfortunately, the grain size of these sugars can vary a lot from manufacturer to manufacturer, which can make a difference in your baking. Most are packaged in a bag with a window, allowing you to check grain size. So long as the turbinado sugar you choose is fine-grained (like granulated sugar) substitution shouldn’t be a problem.
If the sugar is larger-grained (akin to coarse white sparkling sugar or sanding sugar), it may be unreliable for baking and is best used for decorating and garnishing. For instance, I’ve found the turbinado sugar I typically use to sweeten my cup of tea works well when substituted for brown sugar in cake, but does make drop cookies (like the Buttersnaps pictured above) spread more.
What about one of the natural brown sugar alternatives?
We haven’t tested the brown sugar replacements from Swerve or Truvia, the two brands that earn “natural” status. But our experiments with their granulated sugar replacements didn’t go well; for the details, see Sugar alternatives for baking.
What to substitute for brown sugar: the final word
What do you do if you’re all ready to bake but you don’t have the specific brown sugar called for in your recipe? Here are your most reliable choices, in descending order:
- Light brown and dark brown sugar can be substituted for one another; the flavor and color of your baked goods will change slightly.
- Combine white granulated sugar with molasses to make a brown sugar equivalent.
- Use a “raw” sugar; for best results, choose the one whose grain size is most equivalent to that of white granulated sugar.
- In certain cases (see above), substitute white granulated sugar for brown sugar; you’ll lose brown sugar’s flavor and color, and may end up with textural issues as well.
At the end of the day, your best bet is to never run out of brown sugar! But if you do find yourself lacking this key ingredient, now you know how to cope.
