What is Texas Sheet Cake?

Texas Sheet Cake is a basically a chocolate sheet cake, but it’s most known for the stovetop cooked icing that adorns the top. It’s SO good! And a sheet cake is any cake made in a sheet pan or jelly roll pan. Most recipes (like this one) use a half sheet cake pan that’s 18×13 inches. The end result is a cake that’s thin and ready to feed a crowd.

No one knows why chocolate sheet cake is called Texas sheet cake, though you’ll hear many jokes that it’s because the cake is the size of Texas. Another theory is that the recipe became popular there to accommodate large families. Whatever the reason, if you love moist chocolate cake – you need this Texas sheet cake in your life!

How to Make Texas Sheet Cake

One of the great things about chocolate sheet cake is just how easy it is to make. It’s probably one of the easiest ways to make dessert for a crowd.

  1. Preheat the oven. Preheat your oven to 350 and spray with a nonstick baking spray.
  2. Prepare the batter. Combine flour, sugar and salt in a large bowl. Combine cocoa powder with melted butter, then bring to boil with hot water. Pour over the flour and stir to combine. Beat buttermilk and eggs in a separate bowl, then add the baking soda and vanilla. Add to the chocolate mixture.
  3. Bake. Pour the batter into the cake pan. Bake for 15-20 minutes.
  4. Prepare the icing. Boil butter, milk and cocoa powder then remove from heat. Stir in powdered sugar and vanilla. Whisk until no lumps remain.
  5. Ice and serve. Pour the warm icing over the warm cake. Allow to cool and then serve.

Tips for The Best Chocolate Sheet Cake

If this is your first time making Texas sheet cake, here are a few easy tips to keep in mind!

  • Use hot water. Once the butter and cocoa powder are combined, be sure you use hot water, not cold so that things don’t curdle at all.
  • Don’t substitute the buttermilk. The buttermilk is essential for making a proper Texas sheet cake. If you don’t have any on hand, you can make your own by adding a splash of vinegar to regular milk.
  • Add pecans. For a little crunch and extra flavor in the frosting, you can use crushed pecans.
  • Can I make this in a regular cake pan? If you’re just after that rich, chocolate flavor instead of the size, you can make this in a 9×13 cake pan. Just increase the baking time.

Serving Suggestions

Texas sheet cake is perfect for serving big crowds! This chocolate cake recipe is ideal for picnics and potlucks, birthday parties, baby showers, holidays and more. If there was ever a cake that was perfect for almost any situation and guaranteed to make everyone happy, this is it!

When it comes to serving, I usually just do it straight from the pan! Moving this entire cake to a serving dish is difficult and as long as it’s in the sheet pan, it’s easy to transport!

How to Store Leftovers

Leftover chocolate sheet can stay at room temperature for up to 2 days – just be sure to cover it with plastic wrap or foil. However, if you live somewhere warm and humid or want to keep it longer, the fridge is a better option. It will last, covered, for up to 5 days in the fridge.

Can I Freeze Texas Sheet Cake?

Yes, you can freeze this sheet cake – either the entire cake (if your freezer is big enough) or individual slices. It will last for up to 3 months in the freezer. Wrap well in plastic wrap before freezing. Allow to thaw completely in the fridge or on the counter before enjoying.
