This pineapple upside-down cake recipe is made with a boozy and flavorful twist. The cake is made with a buttery brown sugar topping, pineapple rings, and maraschino cherries, and a moist vanilla cake base with bourbon. The bourbon adds a deliciously rich and smoky flavor to the cake. Serve it warm with a dollop of whipped cream or a scoop of vanilla ice cream for a boozy dessert.
