Substituting Soy Milk with Milk

Soy milk introduces a subtle nutty and slightly beany flavor, which can affect the overall taste of the baked good. This change might be more pronounced in delicate recipes like vanilla cakes or light cookies, where the original milk flavor plays a significant role. The sweetness of soy milk is similar to cow's milk if it's unsweetened, but flavored or sweetened varieties might alter the sweetness level, adding complexity or masking other flavors. The acidity level is different as well, potentially impacting recipes that rely on milk's slight acidity for flavor balance.
