Grams to Cups
One cup of golden syrup weighs 340 grams. This distinctively flavored British sweetener — made by refining sugar cane juice — has a buttery, caramel richness that makes it irreplaceable in flapjacks, treacle tarts, and Anzac biscuits.

About Golden Syrup
Golden syrup (also called light treacle) is made through a specific process of refining sugar that produces an inverted sugar syrup with a characteristic amber color and rich, buttery flavor. It is not the same as corn syrup, honey, or maple syrup — its flavor is entirely its own, and it cannot be replaced without changing the character of traditional British recipes.
At 340 g per cup — the same density as honey and corn syrup — golden syrup is thick and flows slowly. Warming the tin or jar in a bowl of hot water makes it easier to pour. For precise measuring, use a kitchen scale: even 5–10 g deviation is noticeable in small-batch baking like tarts and biscuits.
Golden syrup functions as an invert sugar, preventing crystallization in candies and toffees. Combined with bicarbonate of soda (baking soda), it produces the Maillard reaction that gives golden-syrup gingerbread and Anzac biscuits their deep, caramelized color and chewy-crisp texture.
Outside the UK and Commonwealth countries, golden syrup can be found in specialty food stores or ordered online. A reasonable substitute in a pinch is light corn syrup with a small amount of dark molasses added for flavor, though the flavor won't be identical.
Tips for measuring Golden Syrup
- Warm the tin in hot water for a minute — it pours far more easily.
- Use a scale for precision: golden syrup leaves behind residue on measuring cups.
- Oil or wet the measuring cup to help the syrup release cleanly.
- Combine with baking soda for the caramelized color in traditional British biscuits.
Common mistakes
- Substituting corn syrup directly — it lacks golden syrup's distinctive buttery flavor.
- Measuring in a dry cup without oiling it first — up to 20 g can be left behind.
- Baking at too high a temperature — golden syrup burns faster than granulated sugar.
