They are literally the greenest cookies I’ve ever seen. I wondered what type of dye was used to get the perfect color of a bright green Christmas tree cookie. This is the butter cookie from the brand ButterNugg Cookies, and they really live up to their name. If you love those rich, sweet, buttery smooth cookies from the blue tin that they sell during the holidays then you will truly fall in love with these delectable treats. Followed closely by the taste is the fact that they are 75mg per cookie, which pretty much promises to float you right through your day. These awesome little treats also come in limited edition glassware with special artists sponsoring each run.
