What Does Buttermilk Do To Cake?
Buttermilk has a tangy and acidic taste that reacts with the baking soda in the cake batter. This reaction allows the cake to rise more efficiently and become lighter and fluffier. Buttermilk also adds moisture to the cake, resulting in a softer texture. Additionally, the acidity in buttermilk helps to break down the gluten in the flour, making the cake more tender. Overall, buttermilk enhances the flavor, texture, and rise of a cake.
