  • These figures use the metric cup (250 ml). A US cup is slightly smaller at 240 ml, so it holds a little less. Use the US cup converter →
  • Cup sizes are not standard worldwide, so the same cup of an ingredient can weigh more or less depending on the country. What is a cup measurement →

Molasses is a thick, dark syrup produced as a byproduct of refining cane sugar into white crystals. When a recipe calls for it by weight, one metric cup (250 ml) is around 340 grams or 12 ounces. Its bittersweet depth gives gingerbread, treacle tart, and dark rye bread their distinctive flavour.

Molasses clings to measuring cups and spoons, so weighing in grams gives a more reliable result. Pour it directly onto a scale for the cleanest measurement.

  • blackstrap molasses
  • treacle

Honey and molasses are both thick liquid sweeteners and close in weight (honey 350 g, molasses 340 g per cup), but honey is golden and floral while molasses is dark and bittersweet. Use them interchangeably only in recipes that can handle the strong, distinctive flavour of molasses. See what 1 cup of honey is in ounces.

Golden syrup is slightly heavier (350 g vs 340 g per cup) and has a mild buttery toffee taste, while molasses is darker and more bitter. They are not a clean 1:1 swap in flavour-sensitive bakes; weigh and expect a milder, sweeter result from golden syrup. See what 1 cup of golden syrup is in ounces.

Maple syrup is lighter (325 g vs 340 g per cup) and thinner with a delicate caramel taste, while molasses is dense and bittersweet. Swap only in recipes that can handle a much stronger, darker flavour. See what 1 cup of maple syrup is in ounces.

Brown sugar is made by mixing white sugar with molasses, so the two are closely related in flavour. In some recipes you can replace a portion of brown sugar with a smaller amount of molasses, though the texture will change as molasses adds moisture without bulk. See what 1 cup of brown sugar is in ounces.

Palm sugar is a dry, granulated sweetener with earthy, caramel notes that come partly from the same compounds molasses contributes to other sugars. It is not a direct liquid substitute, but the two share a similar flavour role in dark, spiced bakes. See what 1 cup of palm sugar is in ounces.

Parisian essence is a thinner caramel browning liquid, much lighter than molasses (230 g vs 340 g per cup). Use it to deepen the colour and add a malty note to cakes and gravies. See what 1 cup of parisian essence is in ounces.
