Running low on treacle? Here are the best verified substitutes, including how to adjust your measurements.

About treacle
Treacle is a thick, dark syrup produced as a by-product of sugar refining, with a robust, slightly bitter, and distinctly molasses-like flavour. It is most commonly used in British and Australian baking to add deep colour, moisture, and a rich, complex sweetness to cakes, biscuits, puddings, and breads. Black treacle is the darkest and most intensely flavoured variety, while golden syrup is a lighter, sweeter relative often considered a separate product.
Best substitute
Blackstrap or dark molasses is the closest equivalent to black treacle, sharing the same bitter-sweet, robust flavour profile and dark colour. It is the same class of by-product from sugar refining and performs identically in baking applications.
Alternative
Dark muscovado sugar has a very high molasses content and delivers a comparable deep, toffee-like bitterness. Dissolve it in a small amount of warm water to create a syrup before using as a treacle substitute.
Alternative
Golden syrup is a lighter, sweeter, and less bitter form of treacle and works well as a substitute when a milder flavour is acceptable. The resulting bake will be lighter in colour and flavour, lacking the deep, slightly bitter edge of black treacle.

Alternative
Dark corn syrup has a similar viscosity and mild molasses flavour, making it a workable substitute in baked goods and sauces. It is less intensely flavoured and less bitter than black treacle, so the result will be somewhat milder.
Alternative
Pomegranate molasses shares a thick, syrupy consistency and a tart, bittersweet depth that can approximate treacle in certain savoury applications and dark baked goods. It adds a fruity note that works well in marinades and glazes but may alter the flavour profile noticeably in delicate bakes.
