This recipe is a more sophisticated (and boozier) version of one found in Maida Heatter's "Book of Great Chocolate Desserts.” The cake is rich, dense and full of chocolate, with a spicy, peppery, burnt caramel tang.
03Using an electric mixer, beat 1 cup butter until fluffy. Add sugar and beat until well combined. Beat in the eggs, one at a time, beating well between each addition. Beat in the vanilla extract, baking soda and melted chocolate, scraping down sides of bowl with a rubber spatula.
04On low speed, beat in a third of the whiskey mixture. When liquid is absorbed, beat in 1 cup flour. Repeat additions, ending with whiskey mixture. Scrape batter into prepared pan and smooth top. Bake until a cake tester inserted into center of cake comes out clean, about 1 hour 10 minutes for Bundt pan (loaf pans will take less time, start checking them after 55 minutes).
05Transfer cake to a rack. Unmold after 15 minutes and sprinkle warm cake with more whiskey. Let cool before serving, garnished with confectioners’ sugar if you like.
