First, we will look at dark chocolate. Standard dark chocolate has around 12mg of caffeine per ounce. Keep in mind the higher the cocoa percentage in the chocolate, the higher the caffeine content. For example, 85% dark chocolate has about 22mg of caffeine per ounce (starting to see why we said this is almost an impossible question to answer!) Then we will look at milk chocolate, which only contains 9mg of caffeine per ounce. Finally, we have white chocolate, which clocks in at 0mg of caffeine - this is because it contains no cocoa solids; it's cocoa butter with added sugar. Now that we know a little about the caffeine content in different types of chocolate let's try and put this information together to see how many chocolate-covered coffee beans equal a cup of coffee!
