Preheat oven to 350 degrees F (175 degrees C). Grease and flour two 9-inch round cake pans.
In a large bowl, sift together the flour, sugar, cocoa powder, baking soda, baking powder, and salt. Add the eggs, buttermilk, oil, and 1 teaspoon of vanilla, and beat for 2 minutes on medium speed.
Stir in the boiling water and chocolate chips. Pour into prepared pans.
Bake for 30 to 35 minutes in the preheated oven, or until a toothpick inserted into the center of the cake comes out clean. Let cool for 10 minutes, then remove from pans and cool completely.
To make the frosting, cream together the butter, confectioners' sugar, evaporated milk, and 2 teaspoons of vanilla until light and fluffy. Spread over cooled cake.
