Does dark brown sugar have more calories?

Brown sugar is a popular sweetener used in baking, cooking, and beverage making. It comes in two main varieties: light brown sugar and dark brown sugar. Many wonder if there is a difference in calories and nutritional value between the two types. The quick answer is that dark brown sugar does contain slightly more calories per teaspoon than light brown sugar. However, the difference is small enough that most recipes can use either light or dark brown sugar interchangeably. Below we will explore the origins, manufacturing process, and nutrition facts for each variety of brown sugar to understand the subtle differences between them.

What is Brown Sugar?

Brown sugar is a refined sugar product made from white sugar. It derives its color and flavor from the presence of molasses. Molasses is a dark, thick syrup that is produced during the sugar making process. To make brown sugar, some of the molasses is added back into completely refined white sugar.

There are two main types of brown sugar:

Light brown sugar – This contains 3.5% molasses and has a milder flavor and lighter color. It is the most commonly used type of brown sugar.

Dark brown sugar – This sugar contains 6.5% molasses and has a richer flavor and darker color.

Brown sugar can be purchased loose or packed into boxes or bags. Packed brown sugar contains more moisture so it has a softer texture. The moisture also prevents the molasses from crystallizing or hardening. Loose brown sugar has a dry texture and the molasses crystallizes more easily.

Many recipes simply call for “brown sugar” without specifying light or dark. In this case, the light brown variety is most commonly used. However, dark brown sugar can typically be substituted in a 1:1 ratio if desired. The end result will have a more pronounced molasses flavor.

How is Brown Sugar Made?

Brown sugar starts off as sugarcane or sugar beets which are processed into raw sugar. This raw sugar then goes through an affination process where it is dissolved, clarified and decolorized to make pure refined white sugar.

To make light brown sugar, the refined white sugar is combined with a specific proportion of molasses to reach 3.5% molasses content. For dark brown sugar, more molasses is added to achieve 6.5% molasses content. The molasses provides brown sugar with its signature color, moistness, and flavor notes.

The manufacturing process for both light and dark brown sugar is largely the same. The main difference is the percentage of molasses added back in at the end. Producing brown sugar does not require significant additional energy or radically different equipment from white refined sugar. Essentially, the starting material is simply refined white sugar with added molasses to differentiate the final products.

Brown Sugar Nutrition Facts

Since brown sugar is fundamentally refined white sugar with added molasses, its nutritional value is quite similar to white sugar. However, the small addition of the molasses does slightly alter its nutritional profile.

Here is a comparison of the key nutrition facts per teaspoon (4g) of brown sugar vs. white sugar (source):

Nutrient Light Brown Sugar Dark Brown Sugar White Sugar
Calories 15.4 17 16
Total Carbs 4 g 4.5 g 4 g
Fiber 0 g 0 g 0 g
Protein 0 g 0 g 0 g

A few key points:

– Dark brown sugar contains slightly more calories and carbohydrates per teaspoon compared to light brown sugar and white sugar. This is attributable to its higher molasses content.

– However, the difference amounts to only 1-2 calories per teaspoon. This minimal calorie difference is unlikely to be significant for most recipes or diets.

– Brown sugar and white sugar have no fiber or protein. All of their calories come from carbohydrates.

– Nutritionally, both types of brown sugar are very similar to white table sugar. The addition of the molasses does not provide any fiber, vitamins or minerals.

So in summary, the nutrition profile and calorie density is nearly identical between the various sugars. The choice of which to use comes down mainly to flavor preferences.

Effects on Baked Goods

When it comes to baking, does the type of brown sugar used affect the end result?

The difference between light and dark brown sugar in baked goods is subtle. Here is how each type impacts baked products:

Flavor – Dark brown sugar has a more intense molasses flavor. The darker color and richer taste comes through in cookies, cakes and other items where brown sugar is used. Light brown sugar provides a milder flavor.

Moisture content – Dark brown sugar retains a bit more moisture thanks to its higher molasses content. This can help keep some baked goods like cookies chewy. However, for items like cakes, too much moisture can negatively impact rising and structure.

Spreading/browning – The higher moisture in dark brown sugar may facilitate more spread in cookies. And its dark color may promote slightly faster browning. But this is a subtle effect unlikely to ruin a recipe.

Sweetness – White and brown sugars have a nearly identical level of sweetness per teaspoon. The choice between them does not significantly impact sweetness.

Overall, when substituting dark for light brown sugar the effects are fairly minimal. Cookies may end up chewier with a more pronounced flavor. Cakes may rise a bit less and be more dense. But in most recipes, light and dark brown sugars can be used interchangeably without issue. Knowing the flavor and structural changes can help bakers pick the ideal variety for their needs.

Cost Difference

Is there a significant price difference between buying light or dark brown sugar?

Since they originate from the same base ingredients, the production costs are similar. As a result, light and dark brown sugar are typically comparably priced at the grocery store:

– A typical price for a 1 pound bag of light brown sugar is around $1.50

– A 1 pound bag of dark brown sugar also costs approximately $1.50

There can be minor cost fluctuations between different brands. But on average the two varieties have little price difference. Brown sugar tends to cost a bit more than white granulated sugar. But the choice between light and dark does not generally impact the price paid.

Consumers can feel comfortable buying the variety they prefer without having to worry about a major cost penalty. Bakers may want to keep some of each brown sugar type on hand to suit different recipes and desires.

Storage and Handling

Properly storing brown sugar helps retain moisture and prevent hardening. Here are some tips for maximizing shelf life after opening:

– Transfer brown sugar from the original bag into an airtight container. This prevents moisture from escaping.

– If sugar has already hardened, place a slice of bread in the container overnight. This will soften the sugar by morning.

– Store in a cool, dark place. Heat and light can accelerate moisture loss.

– Avoid getting brown sugar wet as this dissolves the molasses. Use dry utensils when scooping.

– Freeze brown sugar for long term storage. This prevents moisture loss for up to 1 year.

– Be sure to press out any air pockets when sealing the storage container. Trapped air hastens moisture loss.

These same storage principles apply equally to both light and dark brown sugar varieties. With proper handling, both types can stay fresh for several months at room temperature or up to 1 year frozen.

Uses in Cooking and Baking

Brown sugar adds more than just sweetness to recipes – its distinctive flavor pairs especially well with certain ingredients. Here are some of the best uses for light and dark brown sugar:

Light Brown Sugar

– Oatmeal – Adding a bit of light brown sugar gives oatmeal extra flavor and sweetness

– Fruit salads – Its mild flavor complements fruits and adds sweetness

– Marinades and barbecue sauce – Light brown sugar provides balanced sweet and tangy notes

– Banana bread – This quick bread gets extra moistness and flavor from light brown sugar

– Chocolate chip cookies – Light brown sugar gives classic cookies sweetness without overpowering chocolate

Dark Brown Sugar

– Gingerbread – The molasses notes pair perfectly with ginger and warm spices

– Baked beans – Dark brown sugar gives this classic side dish balanced sweetness

– Chili – A bit of dark brown sugar helps balance spicy heat and acidity

– Molasses cookies – The rich molasses flavor shines through when using dark brown sugar

– Bacon or ham glaze – Dark brown sugar and pan drippings create a fabulous glaze or sauce

As you can see, both varieties have unique uses based on their flavor profiles. Keeping some of each on hand gives home cooks flexibility in the kitchen.

Substituting Brown and White Sugar

In a pinch, brown and white sugar can be swapped in recipes with a few ratio adjustments:

White sugar replacement – Use 1 cup light brown sugar for every 1 cup white sugar. May need to reduce liquids slightly to account for moisture.

Light brown sugar replacement – Use 1 cup granulated white sugar + 1-2 tsp molasses per 1 cup light brown sugar.

Dark brown sugar replacement – Use 1 cup granulated white sugar + 2-4 tsp molasses per 1 cup dark brown sugar.

The added molasses helps achieve an approximated brown sugar flavor, though it may not be exact. Also reduce oven temperature by 25°F as brown sugar causes more rapid browning.

While possible, substituting between brown and white sugars is not ideal, as it will affect the moisture, texture, and flavor of a recipe. Using the specified type is best when possible.


In summary, dark brown sugar does contain a bit more molasses and about 1-2 additional calories per teaspoon compared to light brown sugar. However, this minor difference has little impact on nutrition and their effects in baking applications are negligible. The choice between light or dark brown sugar in recipes comes down mainly to personal flavor preference. Both can be used almost interchangeably depending on the qualities desired in the finished product. Proper storage of brown sugar maximizes freshness no matter the variety. And both types bring their own unique sweetening and flavor benefits to baked goods and cooking.
