White Texas Sheet Cake

Oklahoma Granny asked about the recipe for the white Texas sheet cake, it is recipe I clipped from a Taste of Home issue years ago. Jeff says he prefers the chocolate Texas sheet cake but he still eats plenty of the white one too.
All its ingredients are basic kitchen staple that I almost always have on hand. It stirs up really quick, no need to get out the mixer either.
However, it is very rich and unless you are an Amish farm worker who burns off a million calories a day, you probably should not eat it very often.

White Texas Sheet Cake
1 cup butter, cubed
1 cup water
2 cups all-purpose flour
2 cups sugar
2 eggs, beaten
1/2 cup sour cream
1 teaspoon salt
1 teaspoon baking powder
1 teaspoon almond extract
1/4 teaspoon baking soda

FROSTING:
1/2 cup butter, cubed
1/4 cup milk
4-1/2 cups confectioners' sugar
1/2 teaspoon almond extract
1 cup chopped walnuts (walnuts are good but I prefer pecans)
Directions
In a large saucepan, bring butter and water just to a boil. Immediately remove from the heat; stir in the flour, sugar, eggs, sour cream, salt, baking powder, extract and baking soda until smooth.
Pour into a greased 15-in. x 10-in. x 1-in. baking pan. Bake at 375° for 18-22 minutes or until golden brown and a toothpick inserted near the center comes out clean. Cool on a wire rack for 20 minutes.
For frosting, in a large saucepan, bring butter and milk just to a boil. Immediately remove from the heat; stir in confectioners' sugar and extract. Stir in walnuts; spread over warm cake. Cool completely. Yield: 20 servings.

I baked it in a 13x9 cake pan instead of a jelly roll pan. It works fine either way.
