Buttery, moist, and covered in an almond flavored frosting, this White Texas Sheet Cake is a tried and true recipe. This white version of the traditional Texas sheet cake is a moist white cake with an almond glaze.
Preheat oven to 375 degrees. Line a 15-in. x 10-in. x 1-in. baking sheet with parchment paper or grease lightly.
In a small saucepan bring butter and water to a boil. Meanwhile, in a large bowl add flour and sugar and mix. Then add in eggs, sour cream, almond extract, baking soda and salt. Slowly pour in the boiling butter/water mixture. Stir until combined. Batter will be very thin.
Pour into prepared baking sheet. Bake for 18-22 minutes or until golden brown. Cool for about 10 minutes. You still want your cake a little warm when you add the frosting so that it spreads well.
For the frosting: In a large saucepan, combine butter and milk. Bring to a boil. Remove from the heat, and then stir in the powdered sugar and almond extract. Stir until smooth and all combined. Spread the warm frosting immediately over warm cake (it will thicken up fast so work quickly). Let frosting set up then cut into squares and serve.
