This is an amazing frozen treat! It takes a little time continuously whisking, but it is definitely worth it. The next time I make it I may double the recipe, it will definitely still fit in the ice cream maker cylinder. I used skim milk because it is what I had on hand and omitted the almonds at the end. I've heard of people using espresso powder instead of instant coffee, but the instant coffee gives a very nice, subtle flavor. Also, some have mentioned using less cornstarch, but I used the full 2 TBSP and thought it came out great. The consistency is ridiculously smooth and I may have added a little more than an ounce of chopped chocolate. Enjoy!
