Preheat oven to 350 degrees.  Grease a 13 x 9 x 2-inch pan; set aside.  Combine flour, sugar, baking soda, and salt; set aside.   In a medium saucepan combine butter, cocoa powder, and 1 cup water.  Bring mixture just to boiling, stirring constantly.  Remove from heat.  Add the chocolate mixture to the flour mixture; beat with an electric mixer on medium speed until combined.  Add the eggs, buttermilk, and vanilla.  Beat for 1 minute (batter will be thin).
