Buttermilk in Baking
Buttermilk is ideal in baking because there's no fat and
it acts very much like whole milk in pancakes and muffins. If you are going to
substitute buttermilk for milk in your recipes, you'll need to change the
amount of baking soda and baking powder as well. This is because of the higher
acid content in buttermilk. You will usually need less baking soda or baking
powder.
For each cup of buttermilk used instead of milk you will
want to use 2 teaspoons less baking powder and add 1/2 teaspoon of baking soda.
