Here is a cookbook of perfect weeknight baking projects from celebrated blogger Sarah Kieffer - inventor of the viral ‘bang the pan’ technique - with 100 delicious cookies organised by type into 8 chapters. Cookies range from classics like chocolate chip to fruity bars and brownies. The recipes, headnotes, and tips feature Kieffer’s thoughtful innovations on techniques and ingredients. The photography, also by Kieffer and shot in her warm, homey style, shows every cookie, as well as step-by-step techniques where appropriate.
