Powdered buttermilk can be great for cooking and baking. It can be used as a substitute for liquid buttermilk or an addition on its own. It adds a tart, dairy flavor to dips and dressings. When stored in a cool, dry place, powdered buttermilk can last up to 10 years.

You usually substitute 1/4 cup of buttermilk (60 mL) mixed with 1 cup of water (240 mL) for every cup (240 mL) of buttermilk in a recipe.

When substituting powdered buttermilk for liquid buttermilk, follow the recipe as you normally would. Simply add your mixture of powdered buttermilk and water when you would normally add the buttermilk. The recipe should turn out more or less the same.
