I would just use instant coffee or a very strong brew like espresso and add that to a protein shake the way you normally make it.

Like a mocha drink. I'd use a little extra ice to offset the coffee heat if you do a brew.

I opted for drinking a coffee-flavored protein shake rather than trying to cream my coffee with whey protein the way I'd do with coffee creamer.
