Ex Input:
I ordered this because so many people were saying that it was sugar free. It's not. The first ingredient is "SUGAR". It's too much of a pain to return, so I'll keep it and drink it (because it's a pretty good K-cup hot chocolate). I will think twice about ordering it again though. I'd really like to get what I ordered.

Ex Input:
i followed the easy instructions and these turned out delicious. i ate them all. there were only 6 of them. i mixed 1/2 cup of milk into the dry mix and slowly mixed it together. i poured the mix into my sprayed cast iron 6 cup muffin pan. i cooked them in my small convection oven and they cooked up nicely. they were moist on the inside. the mixes were very fresh smelling and had a freshness date well into 2013. the pouch is a nice tough plastic one and will keep the mix fresh. it is very easy to open also.
