Now that we know how much caffeine is in a single bean and how much is in an ounce of dark and milk chocolate, let's take a look at how many chocolate-covered espresso beans are in an average-sized (around 95mg) cup of coffee. Drum roll please... 10-20 chocolate covered espresso beans equal a cup of coffee. This answer may not be exactly what you were looking for but, it's helpful to use as a starting point. Now, if you are drinking a stronger cup of coffee (maybe an Americano with two shots of espresso), then it's possible to have around 30-40 chocolate covered espresso beans per cup, but again... this is all dependent on how much caffeine is in the specific kind of bean and type of chocolate used for coating - there truly is no answer that is 100% accurate.
