How To Make Texas Sheet Cake

  1. Preheat oven to 350 degrees F. and spray a 13 x 17 1/2 inch jelly roll pan with cooking spray. You can also line with tin foil if you’d like.
  2. To prepare cake, place 2 sticks of butter in a medium saucepan over medium heat to melt. Stir in water then whisk in cocoa powder until smooth. Stir until mixture comes to a boil then remove from heat and let cool for 10 minutes.
  3. Place flour, sugar, baking soda and salt into a large mixing bowl, stirring to combine. Place buttermilk, eggs and vanilla into a small bowl, whisk then stir into flour mixture. Pour warm chocolate mixture into bowl, slowly. I do this in three phases, stirring in between each. Pour cake batter into jelly roll pan and bake for 18-20 minutes until baked through.
  4. Start preparing icing when there’s 5 minutes of bake time left on the sheet cake. Place milk and cocoa powder into a large saucepan over medium heat, whisking to combine. Stir in softened butter and bring mixture to a boil. When comes to a boil, turn off heat then slowly add powdered sugar whisking very well until icing is a nice consistency. Note, this icing sets up if left alone too long. Needs to be poured over cake as soon as its done. Pour icing over warm cake spreading evenly over sides. Let cake cool for 20 minutes before cutting into squares. Note, using a plastic knife to cut squares helps cut without cake sticking.

Why Is It Called Texas Sheet Cake?

Some say it’s simply because the cake is huge. Others say because it’s because it’s ultra rich. Some point to the addition of ingredients like buttermilk and pecans, or to the fact that the recipe is similar to one submitted to the Dallas Morning News in 1957 that subsequently swept the country.

Once chocolate mixture has cooled for a good 10 minutes, slowly start stirring it into the cake batter. I do this in 3 batches.

What Size Jelly Roll Pan For Texas Sheet Cake?

There are a few different sizes of jelly roll pans, but I found that using the 13 x 17 1/2 inch size is perfect.

Once cake has cooled for about 20 minutes, cut into squares. Using a plastic knife helps prevent sticking. One of my favorite baking tricks.

    I LOOOOVE this cake and have made it many times. However the last few times I made it the icing didn’t get hard. It was very runny. We even did it over a few times and it still didn’t work. However then what we do is poke holes in it and pour the icing over and then its like a POKE cake. It is still delish but I miss that icing. Any insight on why that might happen to me?

    Thanks so much!

      I haven’t had my icing not set before Misty, wonder if you could try adding a bit more powdered sugar next time to see if that helps?

    Thanks For Sharing this Amazing Recipe. My Family Loved It. I will be sharing this Recipe with my Friends. Hope They will like it.

    My great grandmother passed a similar recipe down. Only difference is to add a teaspoon of cinnamon to the cake and to the frosting (sometimes she’d add walnuts too). It’s always a hit!

        Hi Misty,
        I used a smaller pan the first time I made it and couldn’t add all of the sheet cake batter. Just don’t fill it all of the way full to the top of the pan.

    1. Jenny

      Measure it, if it’s close to the size I have listed here it will work. If it’s smaller, just don’t pour all of the cake batter in, you want to leave room for the cake to rise.
