I don’t know where the original recipe for this cake came from, but I always associate this Texas sheet cake with my grandma.
Every time we visited her farm, she made a Texas sheet cake. In fact, it’s the only dessert I ever remember her making.
So, I love this cake – so much so that I even made a cupcake version of it. I love this cake partly out of nostalgia but mostly because it’s moist, chocolate-y, and delicious.
In fact, this is the cake that my son chooses as his birthday cake. Give it a shot, and it may become one of your favorites, too.
How to make Texas sheet cake
Begin by melting the butter in a large saucepan.
I use a large saucepan so that I can mix the cake right in that saucepan.
Once the butter has melted, stir in the water and cocoa powder.
Bring it to a boil, whisking regularly.
Once it's at a boil, stir in the buttermilk.
Remove the pan from the heat.
Stir in the yogurt, eggs, and vanilla until combined.
Add the flour, sugar, baking soda, and salt.
Whisk in just until combined. The batter will be thin.
While the cake is baking, prepare the icing.
Combine the butter, cocoa, and buttermilk in a large saucepan.
Bring to a boil, whisking regularly.
Remove from heat.
Add the powdered sugar and vanilla.
Whisk to combine.
Pour the icing over the hot cake.
Sprinkle with nuts, if using.
Let the cake sit for at least 30 minutes to allow the frosting to set up.
What makes this Texas sheet cake recipe different
I’m all for butter and sugar, but the original recipe for this cake and its icing calls for three sticks of butter.
Over the years, I've tweaked this recipe to make it super moist and tasty while also cutting a full stick of butter from the recipe.
I also cut about a cup of sugar from the original recipe. The cake is still plenty sweet, and we've never missed it.
How to store this cake
The cake is best stored at room temperature. I only cover the cut portions of the cake with plastic wrap because the frosting can get gooey if covered.
How long will the cake keep?
This cake is best eaten in the first 2-3 days after it's made.

I’m all for cutting some of the butter and sugar when the cake maintains it’s moist, delicious taste. Bravo! You did it. We love this cake.

Shelly says
Wonderful recipe! Thank you for sharing it.

Thank you so much! =)

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.

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.
