Muscle Building Chocolate?

I found this Muscle Milk Light "Chocolate Peanut Caramel" bar at Target on sale so I purchased one so I could reveal it to you.  Inside this white plastic-foil wrapper is a 3.25 X 1.25 X 1 inch bar with oozing caramel out of the sides.  It has a very caramel smell with a strong cocoa scent. Cocoa powder is low on the ingredients list however.  This 1.59oz bar has 170 calories composed of 4g
