Caster sugar is more finely milled than granulated sugar, so it dissolves faster and is the better choice for meringues and delicate sponges. They are close in weight (225 g vs 200 g per cup); swap 1:1 by volume in most recipes. See what 1 ounce of caster sugar is in cups.
Brown sugar contains molasses, adding moisture and a caramel flavour that granulated sugar lacks. Packed, it weighs more by cup (220 g vs 200 g), so weigh it when swapping to keep the sweetness and texture on track. See what 1 ounce of brown sugar is in cups.
Icing sugar is granulated sugar ground to a powder, used for frostings and dusting rather than creaming into batters. It packs lighter (125 g vs 200 g per cup), so the two are not a straight 1:1 swap. See what 1 ounce of icing sugar is in cups.
Raw sugar is a coarser, less refined cane sugar with larger crystals and a faint molasses taste. It weighs about the same per cup (200 g each) and swaps 1:1 by volume, adding crunch and a subtle caramel note. See our Raw Sugar converter.
