Can you use buttermilk in a cake recipe instead of water?

Yes, you can use buttermilk in a cake recipe instead of water. It adds moisture and a slight tang, which can enhance the flavor and texture of the cake. Additionally, the acidity in buttermilk can help to tenderize the cake and activate baking soda, resulting in a lighter, fluffier texture. Just be mindful of adjusting the other ingredients if necessary to maintain the right consistency.
