Notes from the book: When the first lady showed up at Crockett Point Baptist Church with a Coca Cola cake, you would have thought that she’d invented homemade gold. Everyone had to have the recipe. In years to come, it morphed into 7-Up cake, Dr. Pepper cake, RC and Moon Pie cake, and Sun Drop cake. Basically, once someone introduced making cakes with soda pop, the experimenting and Christian like competition began.Unknown source
