I purchased these little treats as stocking stuffers for our little furry friends. Both Yorkies LOVED these treats. We had to finally buy more since they liked them so much.

I made cheddar biscuits with this and they came out a little dry the first time, but i adjusted the recipe and they were amazing. I just added a little more milk and another egg. (we have chickens that lay very small eggs, so 3 of our eggs is like 2 large store bought ones.)

I had high hopes for the convenience of this product. My daughter LOVES hot chocolate. This really was a total disappointment. I threw these kcups out. If you use the smallest setting on your Keurig, you get 3 oz of watery hot chocolate. Larger settings are not drinkable. Save your money and get cocoa packets or a good tin of hot cocoa - and take advantage of the instant hot water the keurig provides.
