Texas Sheet Cake

I made this for the 4th of July BBQ we were invited to. It turned out fantastic and I even brought the leftovers to a pool party the next day where it tasted even better! I wouldn't make this for a weekday dessert (the butter content was driving me insane while I was baking :D ). It is definitely an indulgence that is meant to be shared with others.

Texas Sheet Cake

2 cups Flour
2 cups Sugar
¼ teaspoons Salt
4 Tablespoons (heaping) Cocoa
2 sticks Butter
1 cup Boiling Water

2 whole Beaten Eggs
1 teaspoon Baking Soda
1 teaspoon Vanilla

½ cups Finely Chopped Pecans

4 Tablespoons (heaping) Cocoa
6 Tablespoons Milk

1 pound (minus 1/2 Cup) Powdered Sugar

Preparation Instructions
In a mixing bowl, combine flour, sugar, and salt.
In a saucepan, melt butter. Add cocoa. Stir together.
Add boiling water, allow mixture to boil for 30 seconds, then turn off heat. Pour over flour mixture, and stir lightly to cool.
In a measuring cup, pour the buttermilk and add beaten eggs, baking soda, and vanilla. Stir buttermilk mixture into butter/chocolate mixture. Pour into sheet cake pan and bake at 350-degrees for 20 minutes.
