Pistachio Cake

This cake has quite a story - Years ago I was part of a team performing a fraud investigation.  On the back of one of the pieces of evidence was a recipe for pistachio cake.  I told the team that when we finished the investigation I would make this cake.  So, I absolutely cannot site the person who gave me this recipe, but the team LOVED the cake when we celebrated the completion of our work.  I now refer to this as "fraud cake".  Even the green color just seems fitting.  Enjoy!
