What You'll Need

2 sticks butter
1 cup water
2 cups all-purpose flour
2 cups granulated sugar
2 eggs, beaten
1/2 cup sour cream
2 teaspoons salt
1 teaspoon baking powder
2 teaspoons vanilla extract
1/4 teaspoon baking soda
FROSTING:
1 stick butter
6 tablespoons milk
4 tablespoons cocoa powder
3 1/2 to 3-3/4 cups confectioners' sugar
1 teaspoon vanilla extract

What to Do

Preheat oven to 375 degrees F. Coat a 10- x 15-inch rimmed baking sheet with cooking spray.
In a large saucepan over medium heat, bring the 2 sticks butter and water to a boil. Remove from heat; stir in flour, granulated sugar, eggs, sour cream, salt, baking powder, vanilla, and baking soda until smooth. Pour into prepared pan.
Bake 20 to 25 minutes, or until a toothpick inserted in center comes out clean. Cool on a wire rack.
To make the frosting, in a small saucepan over low heat, melt the butter with milk and cocoa powder. Remove from heat and stir in 3-1/2 cups confectioners' sugar and vanilla; mix well, (adding more confectioners' sugar, if necessary, until spreadable) then frost cake.
