In general I'm not a huge fan of Tully's Coffee, but I have a weakness for the bar cookies made by one of their vendors, Seattle wholesaler Finale's Gourmet Desserts. And one of my favorites is their White Chocolate Macadamia brownie.
Now, the name "brownie" is somewhat misleading, because it really is more cookie-like, comprised of Macadamia nut shortbread with white chocolate and caramel in-between. But names aside, it's ridiculously rich, and exceedingly addictive, what with its crunchy top layer, soft midsection and perfect balance of sweet-and-salty; I still don't care much for Tully's coffee, but I will travel for these bars.
