White Texas Sheet Cake

 

1 cup unsalted butter

1 cup water

2 cups all-purpose flour

1½ cups granulated sugar

1 teaspoon baking soda

¼ teaspoon table salt

½ cup sour cream

2 eggs lightly beaten

1 teaspoon clear vanilla extract

 

¾ cup unsalted butter cubed

½ cup milk

6 cups confectioners sugar

½ teaspoon almond extract

2 cups walnuts chopped and divided

Fresh berries for garnish optional (blueberries, strawberries, blackberries, raspberries)

 

Preheat the oven to 350 degrees.  Grease an 18×13” (large jelly roll baking sheet) rimmed ½ sheet pan well with nonstick spray or shortening. a. Note: A large rimmed cookie sheet, or a jelly roll pan works best for this recipe. Using a 9×13 standard cookie sheet is too small. In a medium saucepan, melt the butter over medium/low heat. Once melted, whisk in the water then bring to a low boil for 30 seconds. Remove the saucepan from the heat and let cool for 2 minutes, stirring in intervals. In a large glass mixing bowl, combine the flour, granulated sugar, baking soda, and salt with a spoon or spatula and stir to combine. a. Note: Use a glass that can allow some* heat when the butter/water mixture is added. Pour the warmed butter mixture into the flour and mix by hand with a spatula. Once combined, add the sour cream, eggs, and vanilla. Continue mixing, and make sure to scrape the bottom and sides of the bowl. Pour the batter into the prepared pan and spread evenly with an offset spatula. Bake at 350 degrees for 12-15 minutes until the cake is cooked. While the cake is cooling, make the icing. In a medium saucepan over low heat, melt the butter. Once melted, add the milk and continue whisking until combined. Add 1 cup of confectioner sugar at a time, whisking each time until the sugar is combined. This process will take approximately 5 minutes. Add the almond extract with the final cup of powdered sugar, and then mix until smooth and blended.
