Best Texas sheet cake recipe! This easy, one-bowl 30 minute recipe makes a rich chocolate sheet cake topped with fudgy chocolate icing.
I don’t know where the original recipe for this cake came from, but my grandma made this cake when I was growing up, and it’s a family favorite.
And, really, what’s not to love with this cake! It’s moist, chocolaty, and delicious.
It’s also quick and easy to make. The cake is ready – start to finish – in just 30 minutes. All of which makes it a pretty perfect dessert!
Ingredients and substitutions
- Butter: I use salted butter. If you’re using unsalted butter, increase the salt in the cake to 3/4 teaspoon and add a couple of pinches of salt to the icing.
- Unsweetened cocoa powder: I haven’t tried using Dutch-processed cocoa powder in this recipe.
- Buttermilk: If you don’t have buttermilk, you can make a homemade buttermilk substitute.
- Greek yogurt: Full-fat plain Greek yogurt or sour cream will also work.
- Sugar: I’ve tried cutting the granulated sugar down to 1 cup, and we didn’t notice any difference.
- Powdered sugar: To ensure the smoothest frosting, sift the powdered sugar to break up any lumps.
- Nuts: The nuts are optional. You can also use walnuts if you would prefer to use walnuts instead of pecans.
How to make Texas sheet cake
Step 1: Begin by melting the butter in a large saucepan.
Tip >> I use a large saucepan so that I can mix the cake batter right in that saucepan.
Step 2: Once the butter has melted, stir in the water and cocoa powder. Bring it to a boil, whisking regularly.
Step 3: Once it’s at a boil, stir in the buttermilk. Remove the pan from the heat.
Step 4: Stir in the yogurt, eggs, and vanilla until combined.
Step 5: Add the flour, sugar, baking soda, and salt. Whisk in the flour mixture just until combined. The batter will be thin.
Step 6: Pour the batter into the prepared pan. Bake.
Step 7: While the cake is baking, prepare the icing. Combine the butter, cocoa, and buttermilk in a large saucepan.
Step 8: Bring to a boil, whisking regularly. Remove from heat.
Step 9: Add the powdered sugar and vanilla. Whisk to combine.
Step 10: Pour the icing over the hot cake.
Step 11: Sprinkle with nuts, if using. Let the cake sit for at least 30 minutes to allow the frosting to set up.
Recipe Tips!
- If you use a large saucepan, you can mix up the cake batter in that saucepan.
- You’ll need a jelly roll pan to bake the cake. A jelly roll pan is a rimmed baking sheet that’s about 11×15-inches.
- Parchment paper doesn’t work very well with this cake. The parchment paper can leave a greasy residue with the cake.
- If your icing isn’t as thick as you would like, add additional powdered sugar.
- If your icing is too thick, add an extra splash or two of buttermilk.
Recipe FAQs
I’ve made this recipe for many (many) years. Over the years, I’ve tweaked the recipe to make it super moist and tasty while also cutting a full stick of butter from the recipe.
I’ve also cut a cup of sugar from the original recipe and made a few other adjustments. The cake is still plenty sweet, and we’ve never missed the extra butter or sugar.
It will keep for up to 3 days when properly stored.
You can! The cake works well halved, and you can bake it in a 9×13-inch rimmed baking sheet.
Storage
The cake is best stored in the pan at room temperature. I don’t recommend storing the cake in an airtight container.
I only cover the cut portions of the cake with plastic wrap because the frosting can get gooey if covered. The cake is best eaten within 2-3 days.

Can you substitute splenda for the granulated sugar? If so substitute difference. What about substituting coffee for the water?
Kate says
I haven’t tried subbing splenda for the granulated sugar, so I’m afraid I’m not much help as far as that goes. I don’t see why you couldn’t use coffee in place of the water. Traditionally, the cake has a fairly mild chocolate flavor, and the coffee would just enhance the chocolate flavor.
Julianne says
Thanks for the tip on subbing Greek yogurt.. I love this cake and make it for most events. But I am looking forward to trying this recipe. Have you ever tried reducing the sugar? I think 2 cups of sugar in a cake is way too much. Think I will try that too. Thank you again!
Kate says
I’m glad you found that to be helpful! I have reduced it by about 1/4 cup in the cake and frosting (so not much) without having any issues. When I’ve tried to reduce the sugar in the icing by more, it didn’t set right.

Thank you for sharing this since I am diabetic …..great now I can try this.happy2bschlee@aol.com
Kate says
I’m glad that the substitution helped!! I have several recipes that use Greek yogurt, so please let me know if you’d like me to help you find some of the others, and I’d be happy to help you out. =)

YOU CAN ALSO SUBSTITUTE GREEK YOGURT FOR BUTTERMILK. I NEVER HAVE BUTTERMILK AT MY HOUSE.
Kate says
Thanks! Yes, I use a combo of Greek yogurt and milk or soured milk for buttermilk all the time.
