Texas Sheet Cake is a legendary dessert. This is the BEST Texas Sheet Cake recipe – easy, light and fluffy and VERY decadent. Every bite is chocolaty, rich and delicious without being heavy. My Daddy made these famous and we called them Papa’s Brownies growing up.
An Unforgettable Texas Sheet Cake Recipe
My Dad is a truly unforgettable man and, just like him, the Texas Sheet Cake he used to bake is family legend. As the family story goes, a friend threw a 30th birthday party for my Dad where everybody brought a dessert for a contest. My Dad’s job was to judge each dessert, and as he went down the line he tasted one after another until he got to the Texas Sheet Cake. There he stopped, declared them the winner and refused to try anything else!
These giant pieces of chocolate sheet cake were a staple of my childhood – so much so you could make a family album with just photos where they appeared at a family event. We called them Papa’s Brownies until my brother married a Texas woman and we learned that the recipe was actually for Texas Sheet Cake! Dad passed away in 2016 but we remember him with every pan of Papa’s Brownies we make.
Other Uses for Texas Sheet Cake Frosting

- Hot fudge sauce on ice cream
- Pour over frosting like ganache
- Fruit dip
- Cookie Frosting (You HAVE to try it on my 4 Ingredient Peanut Butter Cookies!)
- Chocolate Drizzle on top of desserts like this Fluffy Peanut Butter Frosting
Texas Sheet Cake Ingredients
There are lots of several ingredients that are popular variations for Texas Sheet Cake. I’m going to address the most common ones here:
- Sour Cream: I make Texas Sheet Cake without sour cream. I don’t think it makes anything better.
- Cake Mix: NO!!! You can’t use a cake mix here. And you don’t need to – the recipe is already crazy simple.
- Buttermilk: I’ve used and not used buttermilk for my Dad’s Texas sheet cake and in the end I don’t think it really matters.
- Nuts: I don’t enjoy nuts on Texas sheet cake. But that is because I’m a texture person and I don’t like the crunchy with the tender cake. If you want to try this use a cup of chopped pecans or walnuts. You can sprinkle them on top or stir them into the frosting.
- Vegetable Shorting: This is a common ingredient to original recipes for Texas Sheet cake. Butter is a great replacement here so I avoid the shorting. Some baking recipes really benefit from shorting. I would never make my pound cake or peanut butter blossoms without it! But Texas Sheet Cake is not one where it matters.
Why Is it Called Texas Sheet Cake?
I love the lore around classic recipes that have been around forever! Nobody knows the history of Texas Sheet Cake for certain. Some say it is because it is a cake the size of Texas. (Everything is bigger in Texas, right?) But the most likely is that current recipes are similar to one published in the Dallas Morning News in 1957. The recipe became very popular and spread from Texas all over the US.
To me this is a classic recipe on the level of great chocolate chip cookies – a recipe that everybody should make often and that children should be raised with. So hats off to the Texans of Dallas or whoever got this particular one going!
What Size of Sheet Cake Pan Do You Need for Texas Sheet Cake?
Sheet cakes are baked in a 13×18″ sheet pan. This is also known as a bakers half sheet. Think of this as a standard cookie pan or jelly roll pan – it is a common household pan versus a full sheet pan which is only common in commercial kitchens.
Buy a Good Quality Pan for Great Sheet Cake
Texas Sheet Cake taught me a valuable cooking lesson! Using a thin, flimsy, cheap sheet pan makes Texas sheet cake rise in hills! Then the frosting goes all over! You don’t have to spend a ton of money to get a solid sheet pan that will last for years. But you should invest in one. I
I use and love Calphalon baking sheets for Texas Sheet Cake. Expect to pay about $15 / pan give or take.

Ingredients
For The Cake
- ½ cup butter
- ½ cup oil
- 1 cup water
- 4 Tablespoons unsweetened baking cocoa
- 2 cups flour
- 2 cups sugar
- 1 teaspoon salt
- 1 teaspoon baking soda
- ½ cup milk
- 2 large eggs
- 1 Tablespoon pure vanilla extract
For the Frosting
- ½ cup salted butter
- 1/3 cup milk
- 4 Tablespoons unsweetened baking cocoa
- 3 1/2 cups powdered sugar this is a one pound bag
- 1 Tablespoon pure vanilla extract
Instructions
For the Cake
- Preheat oven to 350F. Line a rimmed cookie sheet or jellyroll pan (about 12x17) with parchment paper or spray with nonstick spray. The parchment paper protects the pan when you cut the cake.
- Combine butter, oil, water and cocoa powder in a large sauce pan. Bring to a boil over medium heat, whisking frequently so it does not burn. Boil for 30 seconds and remove from heat.
- Meanwhile whisk together flour, sugar, salt, and baking soda in a medium mixing bowl.
- Measure milk in a glass measuring cup. To that add eggs and vanilla. Whisk with a fork and set aside.
- Pour the cocoa mixture (still hot) over the flour mixture. Stir until halfway mixed, add milk mixture. Whisk until just combined and not lumpy.
- Pour into pan and bake at 350 for 15-18 minutes. The cake is done when a toothpick inserted in the center comes clean and corners of the cake just start to pull away from the edges of the pan. (Start working on the frosting while the cake is baking.)
For the Frosting
- Put the butter into the pan you used for brownies, no need to clean in-between. Leave the pan on low heat so butter starts to melt.
- When the cake has been in for 12 minutes turn the pan up to medium. Add the milk and cocoa. Bring to a simmer and cook for about 30 seconds. Remove from heat and whisk in powdered sugar and vanilla. Make sure to whisk out any lumps of sugar.
- Use a rubber spatula to spread hot frosting over hot cake. If your frosting becomes too firm before you pour it, whisk in an extra splash of milk to loosen it up. (Lick the pan...)
- As soon as the frosting sets you can cut and serve the cake. These go great with a scoop of vanilla ice cream. Store leftover cake tightly covered at room temperature for up to five days.

What I want to know is how you get it to bake up level, instead of mounded in the middle and thinner around all the edges.
Mirlandra says
There are two reasons that a sheet cake rises in mountains instead of flat:
1. A cheap pan. You really need a good quality baking sheet. Most of my metal bake-ware is Calphalon at this point. They run about $30 for a set of two which is what the the average cook needs. The pan is heavy duty and does not warp under the brownies. The heavy gauge of the metal creates insulation that allows the batter to all rise at the same rate during baking. I have never had a bad product from Caphalon and am particularity nuts about their pots, frying pans, and bake-ware.
2. Hot spots in your oven. This is a more frustrating problem without a simple fix. First off put an oven thermometer in your oven in a few different spots and find out if it is hot over all or just has some hot spots. If your oven runs hot note by now much and adjust accordingly in all of your baking. You can also try baking one pan at once and center it in the middle of your oven. Halfway through baking open the oven door SLOWLY (to not have a rush of cold air hit the cake fast) and rotate the pan 180degrees. This may help even things out some. You can also try baking at 325 which will take a little longer but this is a more forgiving temperature for ovens with hot spots.
