I save the coffee leftovers of my french press every day, if there are any, and keep them in a container in my fridge. You can have iced coffee, shakes, frappes or cook with it whenever you want.
Source of recipe: I really wanted a shake and coffee. My belly didn't have room for both so I went for it. The banana lends the creaminess along with the peanut butter, and the coffee and cocoa powder compliment each other well. I'd love to have this on the way to work to give me the caffeine I want without the empty calories of a coffee beverage.
