Bob's Red Mill Baking Powder is perfect for all your baking needs, from flaky biscuits and buttery cookies to tender muffins and moist cakes. Dear Friends, As a boy, I loved helping my grandmother make hr famous cinnamon rolls. She told me her secret was simple: always use the very best ingredients. As I grew up, I took her words to heart. I am proud to say my grandmother would approve of the superior baking powder you'll find in the package. It is nothing less than the very best! Happy baking, Bob Moore
