⭐ Buttermilk (Best Nut-Free Option)
1 cup buttermilk per 1 cup whole milkButtermilk contains lactic acid which reacts with baking soda to produce carbon dioxide, improving rise and crumb texture. Its fat content is close to that of whole milk, maintaining moisture and richness in the cake.
For best results, use fresh buttermilk and reduce any additional acidic ingredients slightly to avoid over-acidification. Stir gently to incorporate.
Compared to whole milk, buttermilk imparts a subtle tang and slightly denser crumb but overall enhances the carrot cake's moistness and flavor complexity.
