Instead of the usual artificially-colored-green treats for St. Patrick’s Day, try whipping up these fantastic, easy stout brownies from scratch. Inspired by a recipe from Bon Appétit magazine, this brownie recipe’s secret ingredient is a St. Patrick’s Day must-have, a rich dark stout beer (I prefer Guinness but you could use anything you like.) The secret: reducing the Guinness on the stovetop until its flavors are concentrated. As a result, these brownies are rich, decadent, and gooey. The glaze is definitely gilding the lily, but why not?
