โญ Caster Sugar (Best Vegan Option)
1 cup caster sugar per 1 cup granulated sugarCaster sugar is essentially granulated sugar with smaller crystals, which dissolve more readily in batter. This promotes even mixing and aeration, critical for cupcake rise and texture.
When substituting, use a 1:1 ratio and ensure thorough mixing to avoid graininess. It is especially beneficial in recipes requiring creaming butter and sugar.
Cupcakes made with caster sugar tend to have a lighter, more tender crumb and a more uniform crumb structure compared to granulated sugar.
