Ran out of granulated sugar mid-recipe? Golden Syrup will do the job at 1 cup per cup of sugar, minus 1/4 cup other liquid — 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 golden syrup for the amounts you are most likely to meet. The rule is always the same: 1 cup per cup of sugar, minus 1/4 cup other liquid.
| Granulated sugar called for | Golden syrup to use | Notes |
|---|---|---|
| 1/4 cup | 1/4 cup | |
| 1/3 cup | 1/3 cup | |
| 1/2 cup | 1/2 cup | |
| 2/3 cup | 2/3 cup | |
| 3/4 cup | 3/4 cup | |
| 1 cup | 1 cup | |
| 1 1/2 cups | 1 1/2 cups | |
| 2 cups | 2 cups |
Reduce the other liquid in the recipe by 1/4 cup for every cup of sugar replaced.
By weight, one cup of granulated sugar is about 198 g (King Arthur Baking, spooned and levelled). Our density table does not list a grams-per-cup figure for golden syrup, so no weight is given for it here — measure it by volume and, if the recipe is sensitive, weigh a trial cup yourself and note the number. 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 vanilla sponge cake
A sponge cake is the hardest test of a sweetener swap, because the crumb is delicate and the flavour is mild. A recipe calls for 1 cup of granulated sugar. Using the ratio, that becomes 1 cup. Cream the butter and sweetener as usual, then add the eggs one at a time and fold in the flour. Reduce the other liquid in the recipe by 1/4 cup for every cup of sugar replaced. Bake at the same temperature, but check the cake five minutes early, because a different sweetener can brown faster or set at a different rate. If the sponge is a little denser or a little darker than usual, that is the swap showing — next time, try the swap in a more strongly flavoured cake first.
Example 2: Chocolate chip cookies
Cookies show a sweetener swap in the spread and the chew. A recipe calls for 3/4 cup of granulated sugar. Using the ratio, that becomes 3/4 cup. Cream the butter and sweetener until light, add the eggs and vanilla, then mix in the flour and chocolate chips. Reduce the other liquid in the recipe by 1/4 cup for every cup of sugar replaced. Chill the dough for 30 minutes before baking — chilling matters more than usual here, because a different sweetener changes how the dough hydrates and spreads. Bake one test cookie first: if it spreads too much, chill the dough longer; if it stays too thick, flatten the balls slightly. The chocolate will mask most of the flavour difference.
Example 3: A banana bread
Banana bread is the most forgiving place to try a sweetener swap, because the banana carries the flavour and the crumb is meant to be moist. A recipe calls for 1 cup of granulated sugar. Using the ratio, that becomes 1 cup. Stir the batter until it just comes together, pour it into the tin, and bake as usual. Reduce the other liquid in the recipe by 1/4 cup for every cup of sugar replaced. The loaf will be a little different in sweetness and a little different in moisture, but in a banana bread those differences read as character rather than a mistake. This is the recipe to start with if you have never made this swap before.
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. Golden Syrup 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
Can I use golden syrup 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 golden syrup?
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 golden syrup 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.
Does golden syrup dissolve the same way as granulated sugar?
Not always. Fine and liquid sweeteners dissolve quickly; coarse ones such as demerara and turbinado dissolve slowly and can leave a crunch, which is welcome in a crumble topping and unwelcome in a smooth custard. Date sugar does not dissolve at all. If the recipe needs the sweetener fully dissolved — a syrup, a custard, a smooth frosting — choose a fine or liquid sweetener, or dissolve the substitute in a little warm liquid first and let it cool before adding it.
How much golden syrup do I use instead of 1 cup of granulated sugar?
Use 1 cup — that is the ratio 1 cup per cup of sugar, minus 1/4 cup other liquid applied to one cup. Reduce the other liquid in the recipe by 1/4 cup for every cup of sugar replaced. All amounts on this page are approximate, so if the bake is sensitive, weigh the substitute and note your own number for next time.
Is golden syrup 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.
