This was a really good recipe thank you. I didn't have so substituted choc chips for some random old chocolate bars (dark with nuts, cooking choc with nuts and milk with caramel and nuts) that I chopped up and I also didn't add the reese's. I made my balls about 3 cms and the biscuits turned out huge so I halved the remaining ones to walnut sized and they are a perfect two-chomp treat if you don't like humungous cookies I ended up with over 60!! 40 big ones and 25 ish small. I didn't add as many choc chips as you said, 3 oz or so less and they were still packed. I also flattened them with a fork to make them look more cookie-ish. YUM! - 27 Mar 2016
