I love this stuff. One tablespoon per cup...keep the sugar low (its sweet enough).
It is like drinking a cup full of lucious chocolate---YUM.
Highly recommended. Prices vary from place to place, but I paid about $4/32 oz. or about 85 servings (serving size 1 Tablespoon).
I found that the 'normal' cup size on these things is 6oz.....but most mugs are 10-12 oz so ou will have to double it.
