⭐ Buttermilk Powder (reconstituted) (Best Fat-Free Option)
2 tablespoons buttermilk powder + 2 tablespoons water per 1/4 cup Greek yogurt Quick tip: Adds acidity without extra moisture, but less creamy texture.
Reconstituted buttermilk powder provides the acidity needed for leavening and flavor but lacks the creamy thickness of Greek yogurt. This can affect dough cohesion and final texture.
Mix powder and water thoroughly before adding to dough. You may need to compensate for moisture by slightly reducing other liquids or adding a small amount of butter or oil.
Cookies will have a tangy flavor but may be crisper and less tender due to reduced fat and moisture.
