1.  Bake yellow cake mix acording to box using a 9x13 pan.  (You can also use cupcakes, but will want to make sure to use cupcake wrappers as the pudding icing can get messy while setting up.)

2.  Remove from oven and immediately "punch" holes in the cake using the skinny end of a mixing spoon.  Holes should be about an inch apart

3.  Mix confectioners sugar and pudding mix well before adding milk.  

4.  Slowly add milk with a mixer on low.  Mix for one minute right until pudding starts to thicken. 

5.  Slowly fill in holes with pudding and spread the rest over the top

6.  Refrigerate for 1-2hours and serve cold.
