White Texas Sheet Cake

Jump to Recipe

I love cake and a variety of cake recipes. This white Texas sheet cake is such a yummy recipe. It is soft, moist, and topped with a yummy frosting.

Another really cool thing about this cake is that it feeds quite a few people with a reasonable serving size. While chocolate sheet cake is probably the most popular flavor, I really enjoy this white Texas sheet cake. If you are a fan of cake you have got to try it.

In other countries this type of cake is known as a slab cake. Whatever you want to call it, it is awesome, and super easy to make. If I can do it, you can do it. Let’s get baking!

Step 1: Gather the ingredients

Several cake ingredients in glass bowls on a wooden table.

In order to make a delicious white Texas sheet cake you need the following ingredients:

  • Flour – You can use cake flour or all-purpose flour. If you can find it and afford it, cake flour is the better option, but all-purpose/plain flour works well too.
  • Sugar
  • Baking powder
  • Baking soda
  • Salt
  • Butter
  • Water – I always use filtered water, since my tap water tastes gross.
  • Eggs
  • Sour cream – The sour cream helps to make the cake nice and moist.
  • Vanilla extract


  • Butter
  • Milk – I generally use whole milk, but other milk will work, including almond milk.
  • Powdered sugar – Also known as confectioner’s or icing sugar.
  • Almond extract – Or you can just use vanilla extract.
  • Copped nuts – Pecans or walnuts are commonly used.

Step 2: How to make white Texas sheet cake

Hand whisking, flour, sugar, salt, baking powder, and baking soda in a large glass bowl

Begin by preheating the oven to 375 F/190 C. In a large bowl whisk together the flour, sugar, salt, baking soda, and baking powder and set aside.

Now take a medium pot and add the water and the butter. Heat it up, stirring occasionally, until little bubbles form around the edges. No need to bring it to a boil. Remove it from the heat.

Hand whisking the eggs, sour cream, and vanilla extract.

Now in a small bowl whisk together the eggs, sour cream, and vanilla extract. If you don’t have sour cream you can use this homemade sour cream substitute.

Step 3: Finish the white Texas sheet cake batter

Combining the flour mixture with the butter and water mixture

Now, slowly add the flour mixture to the pot of hot butter and water. Mix until smooth, this will also cool down the liquid a bit, making it safe to add the egg mixture.

Now slowly mix in the egg and sour cream mixture with the main cake batter. Mix until all combined and smooth. And there you go, a simple to make, white Texas sheet cake batter.

Step 4: Bake that sheet cake

Now, take a large greased sheet pan, something like a 10×15 or 11×17 sheet pan. Spray it with cooking spray, or grease it with shortening and dust with flour.

Pour in all the cake batter and make sure it is level. Because it is so runny the cake batter should level on its own without the need to use a spatula.

Bake the cake on the middle rack of the oven for 18 to 22 minutes until a toothpick comes out clean. Let the cake cool for 20 to 30 minutes before frosting it.

Step 5: Frosting for the white Texas Sheet Cake

Frosting ingredients, powdered sugar, milk, butter, vanilla extract, and nuts.

While the cake is cooling it is time to make the frosting. Sure you can just use a store-bought frosting, but really that just won’t do for this awesome cake. Let’s make a special buttercream frosting with pecans.

In a pot, add the milk and the butter, heat it on medium-low heat until you see bubbles around the edges, not boiling. Similar to how the cake was made.

Remove the pot from the stovetop and add in the vanilla extract or almond extract and chopped pecans or walnuts and then whisk or stir in the powdered sugar a little at a time until all combined and you are left with a nice thick frosting. This frosting is amazing.

Pour the frosting out onto the cake and spread it out with a spatula. I really like using a cake spatula because it makes it so much easier.

Now all you need to do is cut into that cake and enjoy! Can you eat just one slice? I know I can’t!

How long does white Texas sheet cake last?

The frosted sheet cake can be stored for 4 to 5 days at room temperature, lightly covered with plastic wrap or stored in an airtight container. Keep it in the fridge to add a few more days of life to it. You may also freeze the cake for a few months if you like.

  • Now in a small bowl mix together your eggs, sour cream and vanilla extract.
  • Next, slowly add the flour mixture to the hot liquid, stirring quickly. Once it is all combined add the egg mixture. The flour will cool down the mixture, so it doesn't cook the egg mixture. Stir in the egg mixture with a wooden spoon until well combined.

  • While the cake is cooling make the frosting. In a saucepot, add your milk and butter. Again, wait till you see little bubbles then remove it from the heat. Again, stir occasionally.
    Now add the pecans or walnuts. Then add in one cup of powdered sugar, followed by the vanilla extract (or almond extract). Then mix in the rest of your powdered sugar one cup at a time until all combined.Β 
  • Frost the cake with a cake spatula or normal spatula. Cut and serve. Enjoy!

  1. Hi Chef….wondering if I can substitute water with something else? juice? buttermilk?

    Is your frosting thick coz all frosting i use is horrible.. please help

    • Hello! Sure you can substitute with buttermilk or normal milk. πŸ™‚ Yes, the frosting is thick. πŸ™‚ But it can be thinned out by adding a little more milk. The trick is to only add the milk a little at a time until you get your desired frosting thickness. πŸ™‚

    This recipe is ideal for someone who has a big family like me! So we always “roll deep” when it comes to parties (even if it’s just a family only gathering). The pecans on top are truly a Texas topping! And I love that the step by step photos made it so easy to follow along and recreate.
