About buttermilk powder
Buttermilk powder is dehydrated cultured buttermilk that has been spray-dried into a fine, shelf-stable powder. It delivers the characteristic tangy flavour and acidity of liquid buttermilk, activating bicarbonate of soda in baking and tenderising gluten for a soft, tender crumb. It is particularly valued for its convenience and long shelf life, making it a pantry staple for bakers who don't regularly use liquid buttermilk.
Best substitute
Reconstituted or fresh liquid buttermilk is the closest equivalent, providing identical acidity and tang. Replace the powder and its associated water with liquid buttermilk, reducing other liquids in the recipe accordingly.
Alternative
Whole milk curdled with lemon juice or white vinegar mimics the acidity and tenderising properties of buttermilk. Add 1 tbsp of lemon juice or white vinegar to 1 cup of milk, stir, and allow to sit for 5–10 minutes until slightly curdled. Use the liquid equivalent in place of reconstituted buttermilk powder.

Alternative
Plain, full-fat yoghurt thinned with a little milk replicates the tangy acidity of buttermilk and works well in baked goods. It has a slightly thicker consistency and richer flavour but produces very similar results in cakes, muffins, and scones.
Alternative
Combining regular skim milk powder with cream of tartar mimics the powdered form of buttermilk and can be used directly in dry mixes or batter. The cream of tartar provides the necessary acidity to activate bicarbonate of soda.
Alternative
Sour cream thinned with milk to a pourable consistency provides similar tang and fat content to buttermilk. It works well in richer baked goods such as cakes, muffins, and quick breads where a slightly denser crumb is acceptable.
