Can I use light brown sugar on its own instead of dark brown sugar?

1 cup packed dark brown sugar = 1 cup packed light brown sugar. Same sugar, same bulk, roughly half the molasses — so sweetness and structure hold and only the depth of flavour drops. Lighter colour and a much gentler caramel note. In gingerbread or a barbecue glaze, where the treacle flavour is the point, the loss is real.

What can I use instead of dark brown sugar?

Q: Can I use dark muscovado sugar instead of dark brown sugar?

1 cup packed dark brown sugar = 1 cup packed dark muscovado. Muscovado is unrefined cane sugar that never had its molasses removed, so it is at least as dark and damp as dark brown sugar. Stronger and slightly smoky, with more mineral bitterness. Welcome in a sticky toffee pudding, assertive in a plain cookie.

Granulated sugar carrying roughly double the molasses of light brown sugar, giving a damp, strongly caramel-flavoured, deeply coloured sugar.

What it does in a recipe: Sweetness with maximum moisture, acidity and treacle flavour — the backbone of gingerbread, barbecue rubs and dense chewy cookies. Pick the swap that covers that job — the ratios below are written so you can act on them without doing any arithmetic.

4 ways to replace dark brown sugar

Granulated sugar + molasses

Closest match

1 cup packed dark brown sugar = 1 cup granulated sugar + 2 tbsp molasses

Doubling the molasses against the light brown formula reproduces the moisture, colour and acidity of the commercial product.

MethodBeat or rub the molasses through until the colour is uniform. At this ratio the mixture goes properly damp and should hold its shape when pressed into a measuring cup.

Trade-offEffectively identical. Mix thoroughly or you will get dark streaks in the finished bake.
