Cocoa powder, an unsweetened chocolate product, adds deep chocolate flavor to desserts and beverages. Cocoa powder occurs when the fat, called cocoa butter, gets removed from the cacao beans during processing. The leftover dried solids get ground into the product sold as cocoa powder.
Cocoa powder is the fine ground brown powder obtained from the partially or completely defatted portion of cocoa liquor or mass of fermented cocoa beans. Commonly used in baking, cocoa powder adds chocolate flavor and a brownish to red color. Commercially, it's available as regular, alkaline or dutch cocoa.
