Texas Sheet Cake

1. Preheat oven to 350F. Coat a 13-by-9-by-2-inch baking pan with cooking spray.
2. To prepare the cake, sift flour, sugar, baking soda and salt into a large bowl.
3.  In a small saucepan, combine butter, water and cocoa. Cook over medium heat, stirring occasionally, until butter melts and mixture comes to a simmer.
4.   Add cocoa mixture, eggs, buttermilk and vanilla to flour mixture; stir to combine. Pour into pan and bake 30 minutes or until a wooden pick inserted in the middle comes out clean. Cool on wire rack. Do not remove from pan.
5.  To prepare the frosting, whisk egg yolks and about 1/3 cup milk in a saucepan. Add remaining milk, vanilla and sugar. Add butter; cook over medium heat, stirring with a wooden spoon, until it comes to a full boil. Reduce heat to maintain boil and cook, stirring frequently, 7 minutes or until thick. Remove from heat and stir in coconut and pecans. Cool, stirring occasionally, until thick enough to spread.
6. Spread frosting over top of cake.
