Cappuccino
Cold is easy. It's just iced coffee, skim milk, sweetener (if you want it**** and a scoop of any kind of protein powder. Powders mix fine with COLD liquids. It's the hot ones that cause the trouble because the powders just turn into nasty balls of goo.
Click makes a REAAAAALY good espresso protein powder, but it's not cheap - about $20 a container, which may make 20 or so shakes..
There are companies that make HOT protein coffee mixes, but the ones I've tried have been painfully oversweetened (sugar-free still, but too sweet for me.)
Here's a link to a place not far from me that sells all manner of protein products, and their hot beverages in particular.

I like the BariWise it mixes good hot. I just mix it with 2-4 oz cold almond milk and than add ho****er. It has caffeine though. My very favorite is Syntax Nectar cappuccino. But, as Bette stated they are really, really sweet. I dilute with decaf coffee. They aren't cheap though.
So after I used my supple up, I take a scoop of my protein powder and mix with the 2-4 oz of almond milk. Shake really well in my Wal-green's blender bottle than I add 8-12 oz hot coffee and enjoy!
