The Most Amazing Texas Sheet Cake is light and fluffy with a deliciously decadent cooked frosting on top. Sprinkle on some chopped pecans or walnuts and you have a sheet cake that people will rave over!

After receiving an insane number of requests, we’ve taken our recipe for The Most Amazing Chocolate Cake and turned it into a Texas Sheet Cake that is absolute perfection. A simple cake batter is made using just one bowl which keeps things nice and easy on this cake. The real highlight of a Texas Sheet Cake is a cooked frosting that is poured over the cake while it is still warm. The cake is often finished off chopped nuts.

Can I make this in a 9×13 pan?

This recipe can be made in a 9×13 pan, however, it will require a longer baking time. A 9×13 cake generally takes 35-40 minutes to bake.

Nuts or no nuts? Do I have to put nuts on a Texas Sheet Cake?

Chopped pecans or walnuts are often spotted on a Texas Sheet Cake. They are completely optional, of course, especially if you are allergic. You can stir the nuts into the frosting itself before pouring it over the cake, or you can sprinkle them on top. It’s up to you!

What size of a sheet cake pan do you use to make Texas Sheet Cake?

Sheet cakes are generally made in an 13×18-inch sheet pan that’s also known as a baker’s half sheet. These sheet pans are common household pans as they are the perfect size to fit into a regular standard size home oven.

  • 1/3 cup unsweetened cocoa powder
  • 1/3 cup buttermilk
  • 3 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1 cup chopped pecans or walnuts
Instructions

FOR THE CAKE

  • Preheat oven to 350 degrees. Lightly grease a 13x18 inch baking sheet.
  • In a large mixing bowl stir together flour, sugar, cocoa, baking soda, and salt.
  • Add eggs, buttermilk, warm water, oil, and vanilla. Whisk until combined and batter is smooth. This should take just a couple of minutes. Pour batter into prepared baking sheet.
  • Bake for 20-25 minutes until a toothpick inserted into the center comes out clean. Cool on a wire rack for 15 minutes before frosting. 

FOR THE FROSTING

  • Melt butter in a medium-sized saucepan over low heat. Whisk in cocoa powder, then pour in buttermilk. Increase heat to medium high and bring to a simmer, whisking constantly. 
  • Once the mixture is simmering, remove from the heat and whisk in powdered sugar and vanilla until smooth. Pour over cake to cover. Use a rubber spatula to smooth out and spread if needed. Sprinkle on chopped pecans. Let the cake and frosting cool completely before cutting and serving.

I used to make a chocolate sheet cake that looked like this, but I had to poke holes in the cake when done and pour the icing on while it was still warm . The icing would drip down into the cake and it was delish!!! Is this a takeoff on that cake? The icing was very thin.

Just made this today and it is so good! Very easy and so delicious. I use powdered buttermilk and it works out great. My batter was thinner than yours looked and it took a little longer to bake. Love this recipe and would love some other flavor sheet cakes in the future.

Hey Rachel,
I’ve watched loads of your videos on YouTube- absolutely love them.
I was just wondering why you don’t have your Most Amazing Chocolate Cake recipe on your website anymore, as your Texas Sheet Cake recipe uses the same recipe, but just less of everything. Is it because it’s an older one?
I was just wondering i you could get it back on. No Pressure!!! 🙂
