Put 4 ice cubes in a shaker bottle; pour coffee on top of ice to cover (4-6 oz); add water on top of that to the 14-16 oz mark; add 1.5 to 2 scoops UMP. Shake, Shake, Shake.
This recipe can be made with regular or decaf...really will have the same taste. I personally use whatever is made at the time, but if you shouldn't have caffeine use decaf.
I put 4 large ice cubes in a shaker, pour coffee over the ice cubes, pour cold water on top to reach the 14-16 oz mark of total liquid, put in my 1.5-2 scoops UMP and shake...shake...shake.
