Calorie counts vary widely across drinking chocolate brands, but the beverage generally contains 48 to 80 calories per 3-tablespoon serving. This does not include additions like milk or cream.
Drinking chocolate is not the same as typical hot cocoa. Whereas hot cocoa is made from cocoa powder and instantly becomes a drink with the addition of liquid, drinking chocolate is made from real chocolate, often in the form of chocolate chunks or shavings packaged in a tin or plastic bag. It is not instant; after adding warm milk, cream or water, the ingredients must be heated and whisked together to form the beverage, which is richer and thicker than typical hot cocoa, due to its higher cocoa butter content.
