Black and Tan Brownies
These Guinness brownies are apt to become your new favorite cookie bar. Historically, the phrase "black and tan" referred to the much-reviled auxiliary force of English soldiers sent to Ireland to suppress the Irish rebels after the 1916 Easter Rising. Eventually, a much-loved drink made with half Guinness Stout and half Harp Lager assumed the name, and now this two-toned brownie (with the addition of Guinness) shares it.
