Ran out of golden syrup mid-recipe? Honey will do the job at 1:1 — but only if you also adjust for what the swap takes away or adds. Sweeteners are not interchangeable by sweetness alone. A liquid sweetener adds water the recipe did not ask for, a dry sweetener may not dissolve the same way, and every sweetener browns at its own speed in the oven — so the swap is really a small recipe adjustment, not just a measuring one. This page gives the ratio, shows it in a table for the amounts you will actually meet, and walks through three real dishes so you can see the swap working in a cake, a batch of cookies and a glaze.
The ratio, in a table
The table below converts golden syrup to honey for the amounts you are most likely to meet. The rule is always the same: 1:1.
| Golden syrup called for | Honey to use |
|---|---|
| 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 |
By weight, one cup of honey is about 336 g (poured, King Arthur Baking). 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. All weights on this page are approximate; verify with a kitchen scale when the result matters.
Worked examples
Example 1: Flapjacks
A recipe for flapjacks calls for 1/2 cup of golden syrup. Using the ratio, that becomes 1/2 cup of honey. Warm the honey gently with the butter and sugar, then mix in the oats and bake. The flapjacks will be a little more floral than the original, but they will be just as chewy and golden — a good swap for a family bake.
Example 2: Sponge cake
A recipe for a sponge cake calls for 1 cup of golden syrup. Using the ratio, that becomes 1 cup of honey. Add the honey with the wet ingredients and bake as usual, checking the cake five minutes early — honey browns at about the same speed as golden syrup, so the timing will be close. The cake will be moist and lightly floral.
Example 3: Glaze for a cake
A recipe for a glaze calls for 1/4 cup of golden syrup. Using the ratio, that becomes 1/4 cup of honey. Warm the honey gently and pour it over the cake. The glaze will be glossy and smooth, with a floral note rather than a buttery one.
What changes in the result
Honey in place of golden syrup is a straight one-to-one swap, and the two are so close that the dish barely changes. Golden syrup is a pale, buttery syrup made from sugar; honey is a floral syrup made by bees. Both are thick, pourable, and sweet, both brown at about the same speed, and both keep a bake moist. The flavour is the difference: golden syrup is buttery and caramel-like, honey is floral and a little more aromatic, so a delicate bake will taste a touch more floral with honey, and a strongly flavoured bake will barely change at all. For most recipes, the swap is seamless.
When not to substitute
Do not make this swap where the golden syrup's buttery flavour is the point of the dish. A treacle tart, a golden syrup cake, or a flapjack that depends on golden syrup's particular caramel-like taste will be different with honey — not wrong, but noticeably more floral. Do not use it in a recipe for someone who cannot eat honey either — honey is not suitable for babies under one year old, and it is not vegan, while golden syrup is. And do not use it where the syrup must stay clear: honey can crystallise in the jar, while golden syrup stays smooth.
Practical guidance
Weighing is the most reliable way to make a sweetener swap, because volume measures 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 syrup pours differently from a dry scoop. Measure liquids in a jug at eye level and dry sweeteners spooned and levelled — except brown sugar, which should be packed firmly. When the swap adds liquid, reduce another liquid in the recipe by the amount the table shows, and check the bake a few minutes early, because a different sweetener can brown faster or set at a different rate. Keep sweeteners sealed and dry; sugar absorbs moisture and odours, and honey and syrups crystallise if they are stored cold — warm the jar gently in hot water to clear it. All amounts on this page are approximate; verify with a kitchen scale when the bake matters.
Frequently asked questions
How much honey do I use instead of 1 cup of golden syrup?
Use 1 cup — the ratio is 1:1. One cup of honey is about 336 g; our density table does not list a grams-per-cup figure for golden syrup, so measure this swap by volume.
Will the flavour change?
A little — golden syrup is buttery and caramel-like, while honey is floral and a little more aromatic. In a strongly flavoured bake the difference barely shows; in a delicate bake it will be noticeable.
Does honey brown like golden syrup?
Yes, at about the same speed. Both are thick, sweet syrups, so the bake will colour at a similar rate. Check the cake five minutes early, as you would with any sweetener swap, and cover the top with foil if it browns too fast.
Can I use honey in a treacle tart?
Not as a straight swap. A treacle tart depends on golden syrup's buttery, caramel-like flavour, and honey will make it taste floral instead. Use the swap in a flapjack or a sponge cake, and keep golden syrup for the tart.
Is honey suitable for babies?
No — honey is not suitable for babies under one year old, while golden syrup is. If the bake is for a baby, keep the golden syrup, or use a different sweetener entirely.
Scaling the swap up or down
A sweetener swap scales linearly in the table — multiply both sides of the ratio by the same factor — but the liquid adjustment matters more in a large bake than in a small one. In a doubled cake, the extra liquid from a syrup, or the missing liquid from a dry sugar, has twice the effect on the batter, so measure the liquid adjustment carefully rather than rounding it. For a very large batch, weigh the sweetener instead of measuring it by volume: a cup of brown sugar weighs more packed than loose, and that difference doubles with the recipe. If you are scaling down to a single serving, use measuring spoons and level them off — a small error in a sweetener matters more in a small bake, where there is less batter to absorb it. All amounts on this page are approximate; verify with a kitchen scale when the bake matters.
If the swap goes wrong — and how to store the substitute
If the cookies spread too much, the dough had too much liquid or the sweetener was too wet — chill the dough for half an hour before baking, and bake one test cookie first. If the cake sinks in the middle, the batter was too wet or the oven was opened too early: check the liquid adjustment, and do not open the oven door until the cake has set. If the glaze is too thin, it needs more sweetener or less liquid — add the sweetener a spoonful at a time until it coats the back of a spoon. Store brown sugar in an airtight container with a clay disc or a slice of bread to stop it hardening, and keep syrups in a cool, dark cupboard.
