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 grams.
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 grams.

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.

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 grams.
