   In a medium bowl, combine 1/2 cup of the butter with the cake mix and egg. Work the mixture with your hands until everything is well blended. The mixture will be crumbly. Press the mixture evenly into a 10 x15 inch jellyroll pan.

   To make the icing, stir together the confectioners' sugar with the water and vanilla until smooth. If the icing is too thick, add more water. If it is too thin, add more confectioners' sugar.
