Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 10-inch Bundt pan.

Combine cake mix, eggs, pudding mix, oil, water, sugar, 1/4 cup coffee liqueur, and vodka in a large bowl; beat for 4 minutes until well mixed. Pour batter into the prepared pan.

Bake in the preheated oven until a toothpick inserted into the center of cake comes out clean, about 40 minutes. Cool on a wire rack.

Stir 1/2 cup confectioners’ sugar and remaining 1/4 cup coffee liqueur together in a small bowl until glaze is smooth.

Turn cake over onto a serving plate; poke cake several times with a fork. Cover with glaze, then dust with remaining 1/2 cup confectioners’ sugar.
