Jaes, Your quest is not difficult and it should not go unrequited. You don't have to become a coffee roasting aficionado, and you don't need to resort to chocolate syrup, unless you want to - I find that solution very much apropos, if you want an additive. However, I've found Trader Joe's Extra Dark Sumatra beans ($5.99/lb), when ground fine, makes an espresso with bold dark chocolate overtones - not undertones or understated in any way; it is like a Hershey's Special Dark bar was melted right in there. I used to import Lavazza Il Perfetto Espresso coffee from Italy, but since finding this offering from TJ's at literally half or less the price, I've given up on the pricey fancy stuff.
