Looks like and tastes like chocolate colored water. No chocolate flavor whatsoever, this was a complete disappointment.  I got the hot chocolate k-cups from swiss miss instead.  How people can be giving this product four and five stars is astounding to me, is the Amazon ratings system being gamed for this product?

Ex Input:
I love this product! It is the best natural sweetener I have ever tried, and I have tried many. You can use also as pancake syrup or as a substitute for honey on your peanut butter and honey sandwich. It last a long time, and is a good value.

These are the most fantastic chips I've ever had!  I could eat the whole bag myself!  They're made with lots of whole grain and beans, and make a complete protein, so I have no qualms about feeding them to my kids as snacks.  They are great!  The only problem I have with them:  The bag is too small!!!  We need a bigger bag!! :)
