This is a blended-coffee treat just like you might buy at a cafe. You can make it non-dairy by using soy milk.
I used a 1-serving packet of the instant coffee granules. It measured almost 2 tsp, and I did use it all. Even using double the amount of coffee that this recipe calls for, it wasn't overkill. I'd recommend increasing the coffee granule amount to 2 tsp if--like me--you love the flavor of coffee. I also used a few more ice cubes so it really was a shake-like consistency. This drink wasn't as sweet as some of the coffee-shop versions, probably because of the use of vanilla rather than the vanilla syrup that the shops use, so I'd probably increase the sugar a bit next time, too. This drink was great topped with whipped topping drizzled with a bit more chocolate syrup. - 01 Mar 2009 (Review from Allrecipes USA and Canada)
Definitely tastes like a frappuccino from Starbucks if you replace the vanilla with Torani brand vanilla which you can find at World Market. I also add 1/4 cup of mini morsels before I blend to have the "java chip" taste. Yum!! - 01 Jun 2009 (Review from Allrecipes USA and Canada)
YUM! I added a full tablespoon of coffee granules for me, because I like a real eye-opener. This is NOM. I'd make this again for sure. EDITED REVIEW: Now that I've adapted a healthier lifestyle and am eating lighter, I cut the milk back a bit and use either two tablespoons french vanilla flavored sugar free creamer or two tablespoons fat free evaporated milk, my homemade sugar free chocolate syrup and if it's not sweet enough, a couple packets Truvia sweetener. It's every bit as good as the full fat version. - 18 Nov 2008 (Review from Allrecipes USA and Canada)
