Ingredients Needed:

  • Butter – use real butter to really help the cake flavor bloom.
  • Water
  • Flour
  • Sugar
  • Eggs
  • Sour cream
  • Salt
  • Baking soda
  • Vanilla extract – almond extract can be substituted

Almond Vs. Vanilla Extract 

The original recipe calls for a full teaspoon of almond extract. Being from the Midwest where vanilla is a more traditional flavor, the almond extract was stronger than we enjoy. 

In our next test we used pure vanilla extract and we haven’t turned back.

This is of course personal preference it I highly recommend using just half of a teaspoon of almond extract on the first test run if that’s the flavor you prefer. 

How to Make White Texas Sheet Cake

Add two sticks of butter and water to a medium saucepan.

Two sticks of butter in a silver pan.

While this mixture is coming to a boil measure dry ingredients and place in a medium sized mixing bowl.

Stir together.

Then pour in boiling liquid and mix well.

Sugar added to melted butter in a sauce pan.

Add sour cream and lightly beaten eggs and add to flour mixture. Stir again.

Pour into a greased jelly roll pan and bake for 20 – 22 minutes in a preheated 375℉ oven.

Allow cake to partially cool.

How to Make The Icing

Measure out confectioners sugar and set aside.

Once the frosting is mixed together it will begin to harden on top fairly quickly. So be sure to focus all of your attention on this icing once you get started.

Using the same sauce pan bring another stick of butter and milk to a boil.

Remove from the heat and add vanilla extract.

Vanilla added to melted butter in a saucepan.

Add powdered sugar.

Powdered sugar added to melted butter and sugar.

Use a whisk to stir until smooth.

Whisk stirring icing until smooth in a medium sauce pan.

As soon as the mixture is smooth pour over the warm, but not hot sheet cake.

This icing sets up very quickly, so pouring as evenly as possible in an effort to avoid trying to smooth the top out with a butter knife or spatula will be best.

Note the top right corner of the cake that I tried to smooth out too late. Working late will do more damage to the finish than just leaving it be.

Recipe Tips and Tricks

  • Cake batter may seem very liquid and this is normal. When poured in a jelly roll pan in a thin layer it will bake and set up quickly and beautifully.
  • Have powdered sugar pre-measured and once added stir quickly and pour over the cake immediately.
  • The icing sets up very fast and is difficult to smooth more than 30 – 60 seconds after being poured out of the warm sauce pan.
  • Icing will run off if the cake is hot, but is more difficult to spread if the cake is cool. So try to make and pour icing quickly when the cake is warm.
  • Can add 1/2 cup of chopped nuts on top of the icing very quickly before it sets up if you like.

    I was wondering if I could use this recipe as a layer cake? Three layer cake. Would there be enough batter for that? Do you think it would work?

    1. Jennifer @ Plowing Through Life says:

      Hey There! I haven’t tested this idea, but it sure does sound good! I do wonder if there would be enough batter or if you would need more like 1.5x or 2x as much batter? Please let me know if you give it a try! Hope you enjoy 🙂
