Aside from milk, though, there are a number of things that you can add to hot chocolate to make it perfect. For one, you will need cocoa powder. You also need a sweetener. One of the best, according to America’s Test Kitchen , is confectioners’ sugar, because it dissolves quickly and thickens the hot chocolate mixture. You should avoid brown sugar, although, as it can give your hot chocolate a syrupy taste and it doesn’t always blend well.
Aside from that, you can also add white chocolate syrup to make the mixture creamier and more complex. According to Reader’s Digest , white chocolates has a rich, buttery, slightly vanilla flavor with hints of sweet cream. This makes the taste of cacao more intense, so adding white chocolate to cocoa powder will give your next cup of hot cocoa a rich flavor that is better than just milk chocolate alone. Want a deeper flavor? You can make your hot chocolate with a mix of dark chocolate powder and white chocolate candy chunks or syrup.
