Set oven to 350. Spray bundt pan with nonstick spray.
Prepare cake mix according to package directions except use vodka in leiu of half the water called for.Mix in chocolate pudding mix. Pour into Bundt pan and bake about 50 mins til cake starts pulling away from sides of pan.
While cake is still hot, flip onto serving platter. Take the box of powdwered sugar and pour into a bowl. Add kahlua a little at a time to make a thin glaze. Pour some over the hot cake, allowing it to soak in.
Once the cake cools entirely, spoon the rest of the glaze over the top. It will set into a nice crust.
To serve, just slice and plate. A dab of whipped cream never hurt anyone.... Just enough shinny to make you feel tight!
