Preheat oven to 350°F. Grease and flour a 12-cup Bundt pan.
In a large bowl, combine cake mix, pudding mix, Kahlúa, water, oil, and eggs. Mix on low speed with an electric mixer until just combined. Scrape down the sides.
Increase speed to medium and beat for 2 to 3 minutes until smooth.
Pour the batter into the prepared pan and smooth the top.
Bake for 45 to 47 minutes, or until a toothpick inserted in the center comes out clean.
Cool the cake in the pan on a wire rack for 15 to 20 minutes.
Invert onto a serving platter and remove the pan.
In a small bowl, whisk powdered sugar and Kahlúa until smooth and lump-free.
Drizzle the glaze over the warm cake, letting it run down the sides and into the center.
Cool completely before serving.
