I am so thrilled by this book. I love the Cake mix doctor books and 101 things to do with cake mix book, too, but honestly I am more of a cookie baker/eater. I always have at least 1 or 2 tubes of the refrigerated cookie dough in my freezer. Never thought about "doctoring" them before I found this book online. Made the toffee chippers and blackberry cheescake bars for the weekend after receiving the book--absolutley perfect and so easy. I agree with the previous reviewer that this is a great one for kids, too. My son had a great time helping to make the toffee chippers
