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

About black treacle
Black treacle is a thick, dark, intensely flavoured syrup produced during the sugar refining process, with a robust, slightly bitter, smoky-sweet taste. It is a staple in British and Australian baking, lending deep colour and complex flavour to gingerbread, Christmas puddings, and dark breads. Its high mineral content and strong molasses character distinguish it from milder golden syrups.
Best substitute
Blackstrap molasses is the closest equivalent to black treacle — both are the final by-product of sugar refining with a similarly intense, slightly bitter flavour and near-identical colour and viscosity. No adjustment is needed in most recipes.
Alternative
Regular (unsulphured) molasses is lighter and less bitter than black treacle but shares a similar caramel-molasses profile. It works well when a slightly milder flavour is acceptable, though the result will be a little less dark and intense.
Alternative
Dark brown sugar contains molasses and delivers a similar deep, caramel richness, though it lacks the liquid consistency and bitter edge of black treacle. Dissolve it in a small amount of warm water before substituting to better approximate the syrup texture.

Alternative
Combining golden syrup with dark brown sugar approximates the sweetness and partial depth of black treacle, though it lacks the pronounced bitterness. Mix equal parts by volume to get closer to the right consistency and colour.
Alternative
Sorghum syrup is a less common but viable alternative, offering an earthy, slightly bitter sweetness that resembles black treacle more closely than golden syrup does. It is more readily available in North America and may be harder to source in Australia.
