How wonderful this treat of coffee and chocolate are! In the middle of a cool winter to have this delicious treat felt like I was in a "SPA". Had everything on hand, however; did not use the guar gum as it just was so good all by itself, and iced up like a frapuccino I saw no reason to add it. The Splenda was a good addition and gave it a nice sweet taste without being overpowering. Will make this a lot during the summer months and drink this to my hearts content. Thank you!
