The Model Bakery has been a fixture in the Napa Valley for 90 years. Today they have two locations - one in St Helena and the other in the Oxbow Public Market. They make their breads, pastries, cakes, pies, cookies, etc from scratch every day. These are their "Chocolate Rads," which are double chocolate chip cookies with walnuts. They are "a radically chocolate cookie (that is) more like a candy bar than a cookie," say the owners.
See their gorgeous english muffins (cooked in clarified butter!) via the last link below. The first 3 links are to bakery's website, Instagram and a short video on Vimeo, where you can see these rad cookies being made. Enjoy!
