Dessert is a fun item to bring to a potluck dinner, and while it can be tempting to try something new, it is safer to simply update an old standby. Prepare brownies according to package directions. Then, to create a glaze, melt semisweet chocolate, butter and a bit of sugar over low heat. Add a splash of your favorite red wine. Pour glaze over fresh-from-the-oven brownies and allow to cool for two hours; cut and serve.
