In a mixing bowl, add sugar, flour and cocoa. Stir and set aside.
Boil butter, oil and water in a saucepan for 1 minute. Pour contents into dry ingredients in mixing bowl. Blend with a mixer on medium speed for 1 minute.
In a separate bowl, whisk eggs and buttermilk together. Pour into contents in mixing bowl.
Mix batter for 1 minute on medium speed until combined.
Pour batter into a 13 X 9 inch greased and floured pan.
Bake at 350 degrees for 35 minutes.
CHOCOLATE ICING
In a saucepan, mix melted butter, cocoa and milk together. Boil for 1 minute. Remove from heat.
Add powdered sugar and vanilla. Blend with a mixer on medium speed until creamy and smooth.
If icing is too thick, add tiny amounts of milk until icing is shiny.
Taste icing. If it is grainy, blend with a mixer on high speed until smooth.
Pour icing over hot cake, starting at edges and working towards middle until cake is completely covered.
Cool for 30 minutes before serving.
Notes
Use a mixer to make the icing or it will not set up properly.
