Understanding the Difference: Brown vs. Raw Sugar
Before attempting a substitution, it's crucial to understand the key differences between these two sweeteners. Brown sugar and raw sugar are not the same, despite their similar color. The variation lies in their processing, molasses content, moisture level, and crystal size.
Brown Sugar: The Chewy Secret
Most commercial brown sugar is essentially refined white granulated sugar with molasses added back into it. The amount of molasses determines if it's light or dark brown sugar. This process gives brown sugar its characteristic moist, soft, and clumpy texture. That high moisture content is what gives baked goods like cookies their signature chewy and tender quality. It also has a distinct, rich caramel or toffee flavor from the molasses. In baking, brown sugar's acidity can react with baking soda, affecting rise and spread. When creaming with butter, it creates fewer air pockets than white sugar due to its density.
Raw Sugar: Coarse and Crunchy
Raw sugar, such as turbinado or demerara, is less processed than both white and brown sugar. It contains some of the sugarcane's natural molasses, giving it a golden color and a mild, honey-like flavor. However, it is significantly drier and has larger, coarser crystals than brown sugar. This larger grain size means it doesn't dissolve as easily into batters and can result in a grainy texture in some delicate baked goods. Because it lacks the high moisture and acidity of brown sugar, it behaves more like white granulated sugar in recipes.
How to Make the Substitution: What to Expect
Directly swapping raw sugar for brown sugar can be done in many cases, but it's important to anticipate changes to the final product's texture, flavor, and appearance.
Baking: The Texture Transformation
- Cookies: If you use raw sugar instead of brown sugar for cookies, you'll likely get a crispier, flatter cookie rather than a soft, chewy one. Brown sugar's moisture is key to the chewy texture. The larger crystals of raw sugar may also make for a less uniform texture.
- Cakes and Muffins: The impact can be less dramatic in moist baked goods. However, raw sugar's dryness can still affect the final crumb and texture, potentially making it denser. The flavor will also be less complex without the molasses.
- Creming: If the recipe involves creaming sugar and butter, raw sugar's coarse crystals can be less effective at aerating the mixture, leading to less rise.
Cooking: Adjustments and Considerations
In cooking applications where the sugar will completely dissolve, such as sauces, marinades, or simple syrups, raw sugar can be a very effective 1:1 substitute. The only noticeable difference will be a slightly different flavor profile. The mild, natural molasses flavor of raw sugar will replace the richer, deeper caramel flavor of brown sugar.
Comparison Table: Raw Sugar vs. Brown Sugar
| Feature | Raw Sugar (Turbinado, Demerara) | Brown Sugar (Light or Dark) |
|---|---|---|
| Processing | Minimally processed; retains some natural molasses. | Refined white sugar with molasses added back. |
| Molasses Content | Small amount, naturally occurring. | Added back; higher for dark brown sugar. |
| Moisture | Significantly drier. | High moisture, soft and clumpy. |
| Crystal Size | Larger and coarser crystals. | Fine crystals, similar to white sugar. |
| Flavor Profile | Mild, subtle caramel or honey notes. | Rich, deep caramel and toffee flavor. |
| Best For | Topping, coffee, glazes. | Chewy baked goods, sauces, marinades. |
| End Result | Crisper, flatter baked goods. | Chewy, moist, tender baked goods. |
Making the Right Choice
To successfully substitute raw sugar for brown sugar, consider these steps:
- Grind the sugar: For baking where a smooth texture is desired, run the raw sugar through a food processor or spice grinder for a finer consistency that will incorporate more easily.
- Increase moisture: In baking recipes, you may need to add a touch of extra liquid, like a tablespoon of milk or water per cup of raw sugar, to compensate for the lost moisture. However, be cautious not to add too much.
- Add flavor: To replicate the deep flavor of molasses, you can add a small amount (1-2 tablespoons) of molasses directly to your batter along with the raw sugar.
- Assess the recipe: For simple recipes where the sugar dissolves, like sauces or beverages, a 1:1 swap is low-risk. For complex baked goods, anticipate the textural changes and decide if they are acceptable.
The Most Reliable Alternative
For the most reliable brown sugar substitute, consider the DIY method: combining white granulated sugar with molasses. This is precisely how commercial brown sugar is made. Simply mix one cup of white sugar with one to two tablespoons of molasses, depending on whether you need light or dark brown sugar. This approach replicates both the moisture and the flavor profile of brown sugar perfectly.
Conclusion: Making an Informed Choice
While it is possible to replace brown sugar with raw sugar, it's not a perfect one-to-one swap. The key differences in moisture and crystal size mean that your final product, especially in baking, will have a different flavor and texture. Raw sugar is drier and coarser, leading to crispier, less chewy results. The best course of action depends on the recipe and your desired outcome. For recipes where the sugar dissolves, raw sugar is a fine substitute. For critical baking, be prepared to make adjustments or opt for a more accurate homemade alternative using molasses and white sugar.

Making an Informed Choice
While you can use raw sugar in place of brown sugar, it's not a perfect one-to-one swap, particularly in baking. The main differences are in moisture and crystal size, which will change the texture and flavor of your final product. For moist baked goods like cookies, the loss of moisture will result in a crispier rather than chewy texture. The larger, coarser crystals of raw sugar may also lead to a grainy mouthfeel if not ground down. For sauces and marinades, the swap is less impactful, though the flavor will be milder. For the most reliable substitution, mixing white sugar and molasses is your best bet.
Final Recommendations
Ultimately, your choice depends on the recipe and your desired outcome. If you're willing to experiment and accept a textural change, a direct swap can work. However, for predictable results that rely on brown sugar's moisture and flavor, either make your own brown sugar with molasses or use a different substitute entirely. Understanding these fundamental differences is the key to successful, and delicious, baking.
