Is it ok to substitute baking powder for baking soda in a cookie recipe?
No. Both baking soda and baking powder are leavening agents, which means they are added to baked goods before cooking to produce carbon dioxide and cause them to ‘rise’. Baking powder contains baking soda, but the two are used under different conditions. Soda needs to react with moisture. Baking powder cntains a drying agent and cream of tartar. Baking soda by itself lacks the acidity to make a cake rise. You can make your own baking powder if you have baking soda and cream of tartar. Simply mix two parts cream of tartar with one part baking soda. But you cannot substitute for baking soda.
