Although I love a traditional chocolate Texas sheet cake, who can resist a buttery vanilla and almond-scented sheet cake? After testing 9 Texas sheet cake recipes in the Texas Sheet cake bake off, I used my best tips and tricks from my favorite cakes to apply to this recipe.

The beauty of any Texas sheet cake lies in its ease to make and serve. The large surface area means one recipe will make a lot of cake! Because you can frost and serve it straight from the pan, it’s an easy, no-fuss recipe for any party.

Tips for making a white Texas sheet cake

Best pan to use: For Texas sheet cakes, I use a half sheet pan (13×18″) since that’s what I have on hand. You can also use a jelly roll pan (10×15″) for a slightly thicker cake that will take a little longer to bake. In a pinch, you can use a 9×13 pan, but the cake will be thicker than a traditional Texas sheet cake.
Grease and flour your pan: This cake can tend to stick to the bottom of your pan. But since it’s served from the pan, lining with parchment paper isn’t ideal as parchment can stick to the cake when serving. Instead, make sure to generously grease the pan and add a sprinkle of flour before pouring in the batter. Tilt the pan around to evenly distribute the flour!
Frost when warm! The key to a perfect Texas sheet cake is to frost the cake while it’s still warm. This allows the icing to easily spread all over and kind of melt into the cake. I like to start the icing right before the cake is done so both are still warm when it’s time to frost.

Ingredients you’ll need for a white Texas sheet cake

Butter: I always use unsalted butter so I can control the level of salt in the recipe.
Oil: While most Texas sheet cake recipes use all butter, I use a mixture of butter and oil for an extra-moist texture.
Sugar: Granulated sugar helps keep the cake texture sweet and tender.
Baking soda: Because this batter is acidic thanks to the sour cream, we use baking soda (a base) to help leaven the batter.
Kosher salt: If you’re using table salt, use half the amount listed. As you may know, table salt is significantly more dense and salty than kosher salt.
Sour cream: Sour cream serves three purposes in this cake. It provides moisture to keep the cake soft, subtle tang for flavor and adds acid to tenderize the batter!
Eggs: As the main binding ingredient, the eggs are best incorporated at room temperature as this will help them emulsify smoothly into the batter. To quickly warm up your eggs, place them in a bowl of hot water for 5 minutes before using.
All-purpose flour: For body and structure, all-purpose flour creates the base of this cake.
Argo® Corn Starch: Replacing a portion of all-purpose flour with Argo® Corn Starch helps reduce the gluten content of the cake. It also ensures the best extra-tender and fluffy cake texture.
Karo® Syrup: The icing on a Texas sheet cake is traditionally made with a boiled icing that gets drizzled all over the warm cake. Adding Karo® Syrup to the icing helps create a smooth, slightly gooier texture with a balanced sweetness that will melt perfectly into the warm cake. Chefs rely on Karo® Syrup for its quality and consistent performance.
Almond and vanilla extract: Almond extract takes this from a basic vanilla cake to a bakery-worthy, almond-scented white cake! If you don’t like almond extract, you can leave it out or use a little less. (I like a lot of almond flavor.)

How to make a white Texas sheet cake?

You’ll follow nearly the same steps as a traditional Texas sheet cake with this white Texas sheet cake. Start by bringing the butter, oil and water to a boil in a small saucepan. While the ingredients are coming to a boil, combine all the dry ingredients (sugar, flour, Argo® Corn Starch, baking soda, and salt) in a medium bowl. Once the butter mixture boils, pour it into the dry ingredients. This hot mixture will help dissolve the sugar granules and the melted butter will make for a dense, moist cake texture.

Whisk the eggs, sour cream, almond and vanilla extract into the batter. Pour into a greased half sheet pan and bake at 350 for 18-23 minutes, or until fragrant with a golden top. An inserted cake tester comes out clean (if you press on the cake with a finger, it should feel firm).

A few minutes before you remove the cake from the oven, melt the butter, milk and Karo® Syrup in a saucepan. Once boiling, remove from heat and add the powdered sugar and extracts and whisk until smooth. Add chopped, toasted pecans, stir to coat, then pour all over your warm cake!

This cake must be frosted after being freshly baked and is best served fresh. I would recommend serving the cake the same day you bake it for the best results!

Storage tips

Any leftovers can be stored at room temperature for 2-3 days. They can also be stored in an airtight container in the fridge for up to one week.

Recipe Variations

For a coconut version, try subbing coconut extract in the cake and frosting. Add 1 cup sweetened shredded coconut to the icing instead of pecans.
