Knowing there’s a difference, I still interchange both Hot Cocoa and Hot Chocolate, just as most other people do.  Guys, it turns out there there is actually a difference between the two. Hot cocoa is normally a mixture of milk (or water), cocoa powder and sugar, along with optional flavorings like vanilla, peppermint and spices like cinnamon. Whilst, hot chocolate is usually a thicker, more decadent drink. It involves real chocolate melted into some milk. The better the quality of the chocolate you use, the more luxurious and decadent the drink.
