I would like to make this as party favors for a bday tonight but how many cookies does it make? I bought small mason jars that can hold 2 cups of water. Would you be able to give me the measurements for a small mason jar? Here is a photo of it compared to a glass: http://i121.photobucket.com/albums/o226/mmhassa2/DSC_0669_zpsc64fa2f6.jpg
She says she uses a 1 quart jar. If there are 4 cups in a quart (I just Googled that), you only need half of her recipe to fill your 2 cup jar.
The blog you linked says she used a QUART jar. Your 2 cup jar is a PINT. You will get two of your pint jars out of that recipe.
