What’s The Difference Between Baking Soda And Baking Powder?

Substituting?

Yes, but carefully:

• Baking soda → baking powder: Use 2 to 3 times more
• Baking powder → baking soda: Only works if you add an acid to the recipe

Storage Tip:

Keep both in a cool, dark spot, and check that expiration date! Old leaveners lose their power—and no one wants flat cookies.
