Ingredients

For the Cake
- 2 cups all-purpose flour
- 2 cups white sugar
- 1 teaspoon baking soda
- ½ teaspoon salt
- ½ cup sour cream
- 2 eggs
- 1 cup butter
- 1 cup water
- 5 tablespoons unsweetened cocoa powder
For the Icing
- 6 tablespoons milk
- 5 tablespoons unsweetened cocoa powder
- ½ cup butter
- 4 cups confectioners’ sugar
- 1 teaspoon vanilla extract
- 1 cup chopped walnuts (Optional)
How To Make Texas Sheet Cake Step by Step

Whisk the Dry Base
In a large mixing bowl, combine the all-purpose flour, white sugar, baking soda, and salt. Whisk these dry items thoroughly until no streaks remain, then set the bowl aside.
Melt the Chocolate Liquid
In a saucepan over medium heat, combine 1 cup of butter, the water, and 5 tablespoons of unsweetened cocoa powder. Bring the mixture to a quick boil, stirring constantly, then remove it from the heat.
Mix the Cake Batter
Pour the hot chocolate mixture into the dry flour base and stir lightly. Add the sour cream and eggs, whisking everything together until your batter is completely smooth and liquid.
Bake to Perfection
Pour your chocolate batter into a well-greased large jelly roll pan. Bake at 400°F (200°C) for exactly 20 minutes, or until a toothpick inserted in the middle comes out clean.
Boil the Fudge Icing
While the cake finishes baking, combine the milk, 5 tablespoons of unsweetened cocoa powder, and ½ cup of butter in a saucepan. Bring to a boil, then remove from the heat source.
Frost and Finish
Whisk the confectioners’ sugar and vanilla extract into the hot icing until smooth. Stir in the chopped walnuts if using, and pour the warm mixture directly over the boiling hot cake.
Tips For The Best Texas Sheet Cake
- Never Wait to Frost: Pour the warm icing over the cake as soon as it leaves the oven; this allows the glaze to sink in slightly for an extra fudgy texture.
- Sift Your Sugar: Always sift the confectioners’ sugar before adding it to the warm saucepan to ensure your finished glaze is completely smooth and free of lumps.
- Check Your Pan: This recipe is specifically designed for large sheet pan cake recipes. Using a standard deep baking dish will change the thickness and require a much longer baking window.
- Room Temperature Dairy: Let your sour cream and eggs sit on the counter briefly before mixing so they blend into the warm batter effortlessly without curdling.
- Toast the Nuts: If you decide to include the optional chopped walnuts, toast them lightly in a dry skillet for three minutes first to release their full aroma.
Variations
- Texas Sheet Cake Brownies: Bake the mixture for an extra three minutes in a slightly smaller pan to create dense, heavy Texas Sheet Cake Brownies with a thick fudge shell.
- Nut-Free Chocolate Square: Simply omit the optional chopped walnuts completely from the warm icing stage to create a silky, kid-friendly velvet surface that everyone can enjoy.
- Texas Chocolate Sheet Cake Bars: Slice the finished cake into long, thin rectangular bars rather than squares for an elegant, portable finger-food option at your next summer picnic.
- Texas Sheet Cake Bundt Cake Style: While this specific liquid batter is optimized for sheet pans, you can look for specialized Texas Sheet Cake Bundt Cake adaptations if you ever want a thick, molded ring presentation.
Storage Instructions
- Fridge: Keep your finished dessert squares covered tightly with plastic wrap in the refrigerator for up to 6 days to maintain optimal freshness.
- Freezer: Wrap individual sliced squares firmly in heavy-duty aluminum foil and store them in a freezer bag for up to 2 months.
- Reheat: Let frozen slices thaw on the counter for 30 minutes, or pop a square in the microwave for 10 seconds to restore that fresh-baked warmth.
Serving and Pairing Ideas

- Serve each rich square warm with a massive scoop of old-fashioned vanilla bean ice cream on the side.
- Pair your afternoon slice beautifully with a tall, ice-cold glass of fresh whole milk or a dark roast espresso.
- Top with a scattering of fresh seasonal raspberries or sliced strawberries to add a bright, tart contrast to the sweet confectioners’ sugar.
- Serve alongside a bowl of freshly whipped cream for guests who want an extra light, airy element with their rich chocolate sponge.
Frequently Asked Questions
Why must the icing be poured over the cake while it is hot?
Pouring the warm chocolate glaze over a hot cake is the traditional secret behind a true Texas Chocolate Sheet Cake. It allows the icing to bond perfectly with the top layer of the cake, trapping moisture inside and forming that iconic crinkly, candy-like fudge crust as it cools.
Can I make this dessert recipe ahead of time?
Yes, this is one of those fantastic desserts that actually improves in flavor and texture the day after it is baked. The deep cocoa notes settle and the sugary glaze fully sets up, making it ideal for party prep.
What can I use if I run out of sour cream?
If you are completely out of sour cream, you can substitute an equal amount of whole buttermilk or plain unsweetened Greek yogurt. This keeps the necessary acidity in the batter to activate the baking soda properly.
My icing is hardening too quickly in the pan, how do I fix it?
Because of the large volume of confectioners’ sugar, the glaze will begin to set up as soon as its temperature drops. Simply place the saucepan back over low heat for a few seconds and whisk vigorously to liquefy it again.
