Add all the ingredients to a blender and blend on high until smooth, about 2 to 3 minutes. Pour into glasses and sprinkle with cocoa powder. Drink up baby!!!
Cook's Note: Chocolate flavored vodka is now being produced by many fine vodka companies. If you can't find it in your liquor store, try butterscotch schnapps. It's less of a mudslide, but every bit as tasty!
Because you cannot enjoy this alone, get a buddy to be bad with.
