Best Brown Sugar Substitutes (With Ratios)
The best brown sugar substitute is homemade: mix 1 cup (200 g) granulated sugar with 1 Tbsp (20 g) molasses for light brown sugar, or 2 Tbsp (40 g) for dark. Use it 1:1, packed, just like store-bought.
Brown sugar substitutes and ratios
| Substitute | Amount per 1 cup packed brown sugar | Best for | Why it works |
|---|---|---|---|
| White sugar + molasses | 1 cup sugar + 1 Tbsp (light) or 2 Tbsp (dark) | Cookies, cakes, sauces, anything | Brown sugar is just sugar coated in molasses |
| Muscovado | 1 cup | Gingerbread, BBQ sauce, sticky toffee pudding | Unrefined cane sugar with natural molasses |
| Coconut sugar | 1 cup | Cookies, crumbles, granola | Similar caramel colour and flavour; drier |
| Granulated white sugar | 1 cup | When you have nothing else | Same sweetness; loses moisture and flavour |
| Demerara or turbinado | 1 cup (grind finer for smooth batters) | Crumbles, toppings, muffins | Light molasses flavour; coarse and dry |
| Maple syrup | 3/4 cup; cut liquid by 3 Tbsp | Quick breads, oatmeal bakes | Adds moisture and caramel notes |
| Date sugar | 1 cup | Crumbles, muffins | Ground dried dates; doesn't dissolve fully |
The science of brown sugar
Commercial brown sugar is white sucrose crystals coated with molasses: about 3.5% for light and 6.5% for dark in typical North American brands. That thin coating changes a lot:
- Moisture. Molasses is rich in glucose and fructose, which are strongly hygroscopic, meaning they attract and hold water. Brown sugar bakes stay soft and chewy, and the sugar packs into a cup.
- Acidity. Molasses is mildly acidic, around pH 5–5.5, so it reacts with baking soda for lift and keeps cookies slightly puffier.
- Browning and flavour. Those simple sugars and trace amino compounds brown faster than plain sucrose, giving toffee, caramel and butterscotch notes.
White sugar alone is dry and neutral, so cookies made with it are thinner, crisper and paler. Coconut sugar and muscovado carry their own molasses-like compounds, which is why they get closest without mixing.
When not to swap
- Butterscotch, toffee and sticky toffee pudding. The molasses flavour is the point; use dark brown sugar, muscovado or the homemade mix.
- Liquid sweeteners in cookies. Maple syrup or honey adds water that makes cookies spread and turn cakey.
- Coconut sugar in very moist recipes. It's fine, but in caramel or fudge it doesn't melt as smoothly.
- Demerara in smooth batters. Large crystals may not dissolve and leave a crunchy speckle.
Questions
Can I use white sugar instead of brown sugar?
Yes, 1:1. Cookies will be crisper, paler and spread more, and you'll lose the caramel flavour. Adding 1 Tbsp molasses per cup brings back most of brown sugar's character.
Can I use dark brown sugar instead of light?
Yes, 1:1. It has about twice as much molasses, so expect deeper colour, stronger flavour and a slightly moister, chewier result.
How do I soften hard brown sugar?
Seal it in a container with a slice of bread or a damp paper towel overnight, or microwave it covered with a damp towel in 20-second bursts. The sugar absorbs the moisture and loosens.
Is coconut sugar a good brown sugar substitute?
Yes, 1:1 by volume. It's drier and less sweet with a toasty flavour, so cookies spread a little less and bakes can be slightly drier.
