As a mother, blogger and wife of a schoolteacher, Crystal Rapinchuk is busy this time of year, when over 50 million kids head back to school (and their parents will drop $75.8 billion in supplies to get them there). In addition to dispensing advice and shopping tips, Rapinchuk also develops recipes for back-to-school treats. Among the most popular is a pan-size Rice Krispies treat slathered with vanilla icing and topped with cookies-and-cream sprinkles. The treat's name? Composition Notebook Cake.
