This is by far the best hot cocoa I have found yet for the Keurig. I love the assortment and the peppermint is my favorite. I would give these try for sure if you are looking for some hot cocoa K-cups. All the other selections for hot cocoa that I have tried were just okay tasting. These are AMAZING!!!! LOVE THEM! I will order these for sure again!

I enjoy them a lot and so does my son. I have to say that this kind is one of my favorites. It is full of peanut butter flavor that you forget that it is only 100 cals. As for the amount you get in the bag, it is more than I expecting so I was very happy.

Buy these cookies. You will not regret it.  They are, hands down, the best store-bought chocolate cookies out there, and I buy every new brand that comes out (from Mrs Fields to all the permuatations offerred by Pepperidge Farms).  These are much better than Entenmann's recent incarnation of "new recipe" chocolate chip cookies, the milk chocolate chip and "soft baked" chocolate chip cookies. Both of these newer cookie species are awful: the milk chocolate tastes like rotting bananas and the cookie part tastes like all the other crappy store-bought soft cookies out there.  In contrast, Entenmann's Original Recipe chocolate cookie is a mind-blowing experience: delicious dark chocolate chips and a soft mouth-watering cookie with a unique but ineffable taste. They seem to have perfected the ratio of flour to sugar, so that the cookie is delicious without weighing you down with excessive sugary sweetness (this is again in contrast to their horrible new cookies).  I have absolutely no idea why Entenmann's decided to nearly eliminate their sales of the classical recipe and replace it with these disgusting brands. It seems to have happened when the Entenmann name was bought by a larger multinational company, so it was probably a money-saving opportunity. The Original Recipe cookies likely have expensive ingredients.  The only problem is they are so hard to find: thank goodness they are now on Amazon!!!
