Related to Icing Sugar

Sugar

Granulated sugar is the coarse crystal that icing sugar is milled from, and it is heavier per cup (200 g vs 125 g), so it will not dissolve smoothly in frostings. Blend it to a fine powder first, or weigh rather than swapping by volume. See our Sugar converter.

Brown Sugar

Brown sugar cannot stand in for icing sugar in an uncooked frosting. Its crystals are coarse and damp, and they stay gritty however long you beat them, so keep brown sugar for the baked part of the recipe and ice the top with icing sugar. See our Brown Sugar converter.

Raw Sugar

Raw sugar has large, coarse crystals with a faint molasses taste, far removed from the fine powder of icing sugar. It packs much heavier (200 g vs 125 g per cup), so the two are not a straight swap. See our Raw Sugar converter.
