⭐ Vegan Buttermilk (Plant Milk + Acid) (Best Vegan Option)
1 cup unsweetened soy or oat milk + 1 tablespoon lemon juice or apple cider vinegar Quick tip: Suitable for dairy-free diets, but may alter flavor and texture slightly.
Plant-based milks combined with acid create a vegan buttermilk substitute that provides acidity for leavening. Soy and oat milks have protein content closer to dairy milk, helping with structure.
Allow the mixture to sit for 5 minutes before use to curdle properly. Avoid sweetened or flavored plant milks.
Biscuits made with this substitute may be slightly less tender and have a different flavor profile, but still achieve good rise and flakiness.
