My dad makes a pot of coffee every morning and there are always a few cups left over. If you dont usually have leftover coffee just make a little bit extra, or make an extra cup in your keurig first thing and put it right into the refrigerator.
I love the individual Hood brand non-fat chocolate milk cartons for 69 cents each. They are great because they are already portioned (1 cup) and I can take them on the go if I need to. You can find them with all of the other milk products at the grocery store.
So here it is- the simplest and greatest thing I have thought of in a long time...combine your chilled leftover coffee and 1 single serve carton of chocolate milk, add ice, mix, and enjoy! Instant non fat Starbucks Cafe Mocha and a great post workout drink too!
