Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 10 inch Bundt pan.
In a large bowl, combine the cake mix, pudding mix, eggs, white sugar, oil, vodka, 1/4 cup liqueur, and water. Beat for four minutes. Pour batter into prepared Bundt pan.
Bake at 350 degrees F (175 degrees C) for 40 minutes, or until toothpick inserted in center of cake comes out clean. Cool on a rack.
Make a glaze by combining 1/4 cup coffee liqueur and 1/2 cup confectioners' sugar. Turn cake over on a cake plate. Poke cake several times with a fork. Cover with glaze, and dust with remaining 1/2 cup confectioners' sugar.
