Sugar Does More Than Sweeten
In baking, sugar isn't just about flavor. It affects texture, moisture, browning, spread, and shelf life. Swapping one sugar for another changes the outcome in ways that go beyond sweetness. Understanding what each type does helps you make smart substitutions — or know when not to substitute at all.
Granulated Sugar
Weight: 200g per cup.
Standard white granulated sugar is refined sucrose. It dissolves cleanly and has a neutral sweetness. It produces a crisp edge on cookies, a light crumb in cakes, and a predictable level of browning. When you cream it with butter, the sharp crystals cut into the fat and create air pockets. This is the default sugar in most baking recipes.
Brown Sugar
Weight: 220g per cup (packed).
Brown sugar is granulated sugar with molasses added back in. Light brown sugar has about 3.5% molasses; dark brown sugar has about 6.5%. The molasses adds moisture, a slightly acidic pH, and a caramel-butterscotch flavor.
In cookies, brown sugar produces a chewier, more moist result because molasses is hygroscopic — it pulls water from the air. Cookies made with all brown sugar spread less and stay soft longer. Cookies made with all white sugar spread more and turn crispy.
Many cookie recipes use a mix of both to get the best of both worlds: some spread, some chew, balanced flavor.
Light vs. Dark Brown Sugar
You can use them interchangeably in most recipes. Dark brown sugar has a stronger molasses flavor and slightly more moisture. Switching from light to dark (or vice versa) changes the flavor a bit but won't break the recipe.
Powdered Sugar
Weight: 120g per cup.
Powdered sugar (also called confectioners' sugar or icing sugar) is granulated sugar ground to a fine powder with about 3% cornstarch added to prevent clumping. It dissolves almost instantly, which makes it ideal for frostings, glazes, and dustings.
Don't substitute powdered sugar for granulated in recipes that call for creaming. The cornstarch and fine texture change the way it interacts with fat, and you won't get the same air incorporation. Powdered sugar is also the reason some shortbread and Mexican wedding cookies have that melt-in-your-mouth texture — the fine particles create a sandy, tender crumb.
Honey
Weight: 340g per cup.
Honey is about 25% water and significantly heavier than granulated sugar by volume. It's sweeter than sugar, so you need less of it — typically 3/4 cup of honey replaces 1 cup of sugar. Because of the extra liquid, reduce other liquids in the recipe by about 3 tablespoons per cup of honey used.
Honey browns faster than sugar, so lower your oven temperature by about 15°C (25°F). It also makes baked goods denser and more moist. Honey works well in quick breads, granola, and some cookie recipes. Its flavor ranges from mild (clover) to strong (buckwheat), so choose accordingly.
Maple Syrup
Weight: 322g per cup.
Real maple syrup (not pancake syrup, which is mostly corn syrup) has a distinctive flavor that works in specific contexts — oatmeal cookies, spice cakes, pecan pies, and anything with warm spices. Use 3/4 cup maple syrup per 1 cup of sugar, and reduce other liquids by 3 tablespoons.
Grade A Dark or Very Dark has the strongest maple flavor and stands up best to other ingredients. Lighter grades can get lost in baking.
Raw and Specialty Sugars
Turbinado, demerara, and muscovado are less refined sugars that retain some natural molasses. Turbinado and demerara have large crystals that add crunch — sprinkle them on top of muffins and scones before baking. Muscovado is sticky and moist, similar to dark brown sugar but with a deeper, more complex flavor. Coconut sugar has a low glycemic index and tastes like brown sugar with a hint of caramel. Use it 1:1 for granulated sugar, but expect a darker color and slightly drier texture.
