Substituting Unsalted Butter with Greek Yogurt

Greek yogurt will impart a tangy flavor to the baked goods, which can alter the intended sweetness and balance of flavors. The natural acidity of Greek yogurt can enhance certain flavors, making them more pronounced, but it may also clash with sweeter profiles. While butter adds a rich, creamy, and slightly nutty flavor, Greek yogurt introduces a mild sourness that can add complexity or be overpowering if not balanced with other ingredients.
