I'm wondering which ones taste the best and are easy to find.
I really like my own that my son calls a Fluffy Latte.
You put ice in a glass, poor coffee over it half way up. Add a splenda (or your sweetener of choice) and a little vanilla creamer and then enough coffee ice cream to get the liquid to fill the glass and drink with a straw.
pretty good.

I'd like to hear of some other ones, whether you make them yourself or get them at a coffee shop or wherever.
