hen I need an impressive dessert in a hurry, I pull out my Bundt pan. Though the batter is no more involved than any other cake, the big, fluted finished cake looks like it took a lot of work or special skill. Even better, Bundt cakes don’t require frosting, layering or any other decoration beyond a dusting of powdered sugar and a dollop of whipped cream on each slice. This particular Bundt cake replaces sweet icing with a heady mixture of whiskey, black coffee, butter and brown sugar, which is spooned over the still-warm cake to soak in and glaze it as it cools.
