Whereas cocoa powder is made with cocoa beans that have been fermented, roasted, and processed in high heats, raw cacao powder is the far more unprocessed predecessor. Raw cacao powder is made by cold-pressing the unroasted cacao beans (to separate them into cocoa butter and cacao powder). Because of the lack of processing, cacao powder is packed with minerals, antioxidants, flavonoids, and living enzymes. In fact, it is often considered a superfood with heart, skin, and mood-enhancing benefits. In terms of flavor, cacao powder is richer but also more bitter. In comparison, cocoa powder is more mellow with a more rounded flavor, yet you miss out on the extra nutrients and antioxidants, etc. Though either is healthier than using chocolate to make a healthy hot chocolate.
