The BakerBettie.com website is where she shares her recipes, classic baking techniques & approachable baking science tips.

Sally is a mother, baker, blogger, author, and food photographer. She started Sally's Baking Addiction in 2011 as a personal blog. Her small hobby blog quickly ignited a passion for food photography as well as a desire to teach others?not just what to bake, but how to bake.

Just a year and a half after launching the blog, Sally quit her full-time job to build Sally's Baking Addiction into the business it is today. She has written, photographed, and published more than a thousand from-scratch recipes and written three cookbooks.
