As any baker knows, baking powder is absolutely indispensable in the kitchen—it helps gives baked goods the rise and airy texture we all love. Baking powder is a mix of baking soda (which is alkaline), a weak acid, and a buffer, which prevents the baking soda and acid from reacting prematurely. When this acid-base reaction occurs during the baking process, gas bubbles form and cause the dough to rise. 
 
Most baking powders use cornstarch as their buffer. This can be a concern for many health-conscious shoppers. GRAIN FREE PLANET baking powder is double-acting, aluminum free, corn free, so of course 100% grain free.  It includes certified non-GMO tapioca starch, so you can be confident no GMOs are sneaking into your baked goods!
