dark chocolate pudding

What a mess.  My first ever attempt to make chocolate pudding.  It called for 6 cups of cold whole milk, an electric whisker on medium speed and all blended in a large mixing bowl.  Well, the wet powered mix flew everywhere - on the counter top, the back splash, the floor and all over the front of my clothes, up and down.  And boy, did I get into trouble.  Eventually it was all cleaned up, which took longer than it did to make.  But now it's good enough - and only wish there sat a cherry on the top.
