Which one tastes better in a cake recipe buttermilk or whole milk?

Buttermilk generally enhances the flavor and texture of a cake more than whole milk. Its acidity helps to tenderize the gluten in the flour, resulting in a lighter, fluffier cake. Additionally, buttermilk adds a subtle tanginess that can deepen the overall flavor profile, making it a popular choice among bakers. Whole milk, while still good, may not provide the same level of richness or complexity.
