Ran out of granulated sugar mid-recipe? Demerara Sugar will do the job at 1:1 (crunchier texture) — but only if you also adjust for what the swap takes away or adds. Sugar is a dry ingredient that behaves like a liquid once it melts: it holds moisture, delays the setting of the crumb, and browns in the oven. A liquid sweetener adds water the recipe did not ask for; a dry sweetener may not dissolve the same way; a high-intensity sweetener adds sweetness without any of sugar's bulk at all. Each of those differences needs a small correction, and this page lists them.

The conversion table below covers every amount you are likely to meet, from a tablespoon to two cups. After it come three worked examples with real numbers, a section on what changes in flavour, texture and browning, and the recipes where you should not substitute at all — candy, meringue and jam are the usual casualties. Sweeteners differ in sweetness, moisture and browning; liquid sweeteners need the recipe's liquid reduced.

The ratio, in a table

The table below converts granulated sugar to demerara sugar for the amounts you are most likely to meet. The rule is always the same: 1:1 (crunchier texture).

Granulated sugar called for Demerara sugar to use Approximate weight Notes
1/4 cup 1/4 cup about 55 g
1/3 cup 1/3 cup about 73 g
1/2 cup 1/2 cup about 110 g
2/3 cup 2/3 cup about 147 g
3/4 cup 3/4 cup about 165 g
1 cup 1 cup about 220 g
1 1/2 cups 1 1/2 cups about 330 g
2 cups 2 cups about 440 g

By weight, one cup of granulated sugar is about 198 g and one cup of demerara sugar is about 220 g (King Arthur Baking, spooned and levelled). The two do not weigh the same cup for cup, which is why weighing is more reliable than scooping for this swap. All weights here are approximate — verify with a kitchen scale when the bake matters.

King Arthur lists 198 g per cup; USDA FoodData Central rounds granulated sugar to 200 g per cup. The 2 g difference is rounding, not a real disagreement.

Worked examples

Example 1: A batch of muffins

Muffins are a good middle ground: more forgiving than a sponge cake, less forgiving than shortbread. A recipe calls for 3/4 cup of granulated sugar. Using the ratio, that becomes 3/4 cup. Mix the wet and dry ingredients separately, then combine with as few strokes as possible — the batter should look lumpy. Fill the cups two-thirds full and bake as usual. The muffins will have a slightly different crumb and may brown a little faster on top, so check them a few minutes early. If the tops brown too fast, cover the tin loosely with foil for the last few minutes.

Example 2: Brownies

Brownies are one of the easiest bakes to swap a sweetener in, because the chocolate does most of the work. A recipe calls for 1 1/2 cups of granulated sugar. Using the ratio, that becomes 1 1/2 cups. Melt the butter and chocolate, stir in the sweetener and eggs, then fold in the flour. Bake as usual and check five minutes early. The brownies will be fudgy and rich, and the sweetener swap will be almost impossible to detect under the chocolate. If the swap adds a strong flavour of its own, brownies are the recipe where that flavour works best.

Example 3: Shortbread

Shortbread is a strict test, because it has only three ingredients and the sugar is one of them. A recipe calls for 1/2 cup of granulated sugar. Using the ratio, that becomes 1/2 cup. Cream the butter and sweetener, then mix in the flour until the dough just comes together — do not overwork it, or the shortbread will be tough. Press the dough into the tin, prick it with a fork, and bake at a low oven until pale gold. Shortbread should be pale, not brown, so if your substitute browns faster, lower the oven by 25°F and watch it closely. The texture will be a little different, but a good shortbread is still a good shortbread.

What changes in the result

The most visible change is usually the browning. Sugar caramelises in the oven, and that caramelisation is what gives a cake its golden top and a cookie its crisp edge. Demerara Sugar browns differently — faster, slower, or with a different colour — so the bake can look done before it is done, or stay pale when it is ready. Check with a skewer rather than by colour, and be ready to cover the top with foil if it browns too fast. The second change is the texture: a liquid sweetener makes a moister, softer crumb, while a dry substitute can make a drier one. The third is the flavour: Sweeteners differ in sweetness, moisture and browning; liquid sweeteners need the recipe's liquid reduced. In a strongly flavoured bake that character is welcome; in a delicate bake it can dominate. The fourth is the keeping quality: bakes made with liquid sweeteners often stay moist for longer, which is an advantage for anything eaten over several days.

When not to substitute

Do not swap 1:1 in candy-making, meringues or jam, where sugar's exact chemistry matters. In practice that means: do not make this swap in candy-making, where sugar's exact boiling behaviour is the whole recipe; do not make it in meringues, where sugar stabilises the egg white foam and a substitute can make the meringue weep or collapse; and do not make it in jam or preserves, where sugar is the preservative and getting it wrong is a food-safety issue, not just a taste issue. Be cautious in shortbread and in any recipe where sugar is a large share of the weight. And if the recipe is for someone managing blood sugar, remember that a different sweetener is not automatically a safe one — check with the person, and do not present a swap as a health claim.

Practical guidance

Weighing is the most reliable way to make this swap, because volume measures for sweeteners are inconsistent: a cup of brown sugar weighs more packed than loose, a cup of honey weighs far more than a cup of sugar, and a teaspoon of stevia weighs almost nothing. Use the weights on this page as a starting point, verify them with your own scale, and write the number down for next time. If you do not have a scale, measure liquids in a jug at eye level and dry sweeteners spooned and levelled — except brown sugar, which should be packed. Keep the substitute sealed and dry; sugar absorbs moisture and odours, and a damp cupboard will turn it into a solid lump.

All conversions on this page are approximate. A kitchen scale is the most reliable tool you own: weigh the substitute, note the number that works for your recipe, and use it next time. If a bake matters — a birthday cake, a loaf for guests — test the swap first in a small, forgiving recipe before you commit to the important one.

Frequently asked questions

Is demerara sugar sweeter than granulated sugar?

Sweeteners differ in sweetness, moisture and browning; liquid sweeteners need the recipe's liquid reduced. Sweetness is not the whole story, though: a sweetener can match sugar's sweetness and still change the bake, because sugar also controls moisture, browning, spread and texture. Judge the swap on the finished bake, not on a spoonful of the sweetener, and adjust the amount slightly next time if the result is too sweet or not sweet enough.

Will my cake brown more with demerara sugar?

Possibly — and it depends on the sweetener. Liquid sweeteners and those with more fructose tend to brown faster, so a cake can look done before the centre is set. Check with a skewer rather than by colour, and if the top is browning too fast, cover the tin loosely with foil for the last part of the bake. If your substitute browns more slowly, the cake may look pale when it is ready — again, trust the skewer, not the colour.

Can I use demerara sugar in cookies?

Yes, but expect the cookies to behave differently. Sugar controls spread: it melts in the oven and lets the dough spread before it sets. A substitute changes that balance, so the cookies may be thicker or thinner than the recipe intends. Chill the dough for 30 minutes and bake one test cookie first. If the cookies spread too much, chill the dough longer; if they stay too thick, flatten the balls slightly. The flavour difference will be small under the chocolate or spice.

Can I use demerara sugar in meringue or candy?

No — not safely, and not with a good result. Meringue depends on sugar to stabilise the egg-white foam, and candy depends on sugar's exact boiling behaviour; a substitute changes both, and the result can be a weeping meringue or a candy that never sets. Jam is the same: sugar is the preservative, and getting it wrong is a food-safety issue. For those recipes, use the sugar the recipe calls for, or find a recipe written for the substitute from the start.

Will the texture change with demerara sugar?

Yes, a little. Sugar tenderises crumb, controls spread and holds moisture, and every substitute shifts that balance. A liquid sweetener usually makes a moister, softer crumb; a dry substitute can make a drier one; a high-intensity sweetener adds sweetness without any of sugar's bulk, so the bake can be drier and less tender. The changes are small in a strongly flavoured bake and most noticeable in a plain cake or a cookie. If the texture matters, try the swap first in a forgiving recipe such as banana bread or brownies.

Can I use demerara sugar in tea and coffee?

It depends on the sweetener. Dry sweeteners that dissolve well work in hot drinks; liquid sweeteners work too, though they add a flavour of their own. Sweeteners that do not dissolve — date sugar is the classic example — will sit at the bottom of the cup and are best kept for baking. High-intensity sweeteners need only a tiny amount in a drink, so measure carefully: a pinch too much can make a cup of tea unpleasantly sweet. Taste as you go.
