What is a Texas Sheet Cake?
- Chocolate sheet cakes are not fussy. The batter comes together so quickly, it bakes in just 20 minutes, you make the frosting while it bakes and pour over the warm cake.
- It’s chocolate-y, but not overly so, allowing the slight tang of the buttermilk to shine through. While it’s dense, it’s also rich and has a slight chewy factor.
- The easy, cooked chocolate frosting pours on while warm, then sets with a little crust that makes your taste buds scream for more.
Pioneer Woman Chocolate Sheet Cake
I have been making this Texas Sheet Cake recipe for years, in fact, it’s from one of my favorite cookbook authors and bloggers, the Pioneer Woman. It’s an oldie but such a goodie! We use buttermilk in our recipe, which we think makes it the best Texas Sheet cake recipe, adding moisture, richness and all around deliciousness.
I have definitely made some tweaks to make it work for high altitude, but have no fear you sea level dwellers, I have the original amounts as well.
Recipe adapted from The Pioneer Woman.
Why is it called Texas Sheet Cake?
- Where’d it get its name? Legend has it, because it’s huge, like the state of Texas.
- Others say it’s because it’s dark and rich, like the oil that flows from the ground in Texas.
- Still others say it’s because it’s loaded with Texas-y 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. (Source)
Regardless of what you call it, Pioneer Woman chocolate sheet cake or Old Fashioned Texas Sheet Cake or the “Get-in-my-mouth-now” cake — I don’t really care, but you and your loved ones will care very much when they sink their teeth into this rich, slightly chewy, chocolatey cake.
INGREDIENTS
- all-purpose flour | I use organic unbleached all purpose flour, regular flour is fine, just not self-rising.
- granulated sugar | I use all natural cane sugar, but you can replace it with white sugar
- light brown sugar | this is my addition, to add a bit more of a molasses taste and a bit more chewiness
- salt
- cocoa powder | use whatever kind you have, I love Rodelle’s Dutch Process Cocoa Powder
- butter | the real deal please, my mantra “If it’s soft coming out of the fridge, it’s not real butter” no oil blends
- boiling water | does a little sciencey magic thing — blooming the cocoa powder!
- buttermilk | No buttermilk? No problem, see my handy substitutions chart for this and many other baking ingredients substitutions. I use whole full fat buttermilk, cause it’s so good in this cake!
- eggs | provides the lovely lift and lightness to the cake
- baking soda | Make sure it’s fresh and not out of date
- vanilla extract | I always put a little extra in and homemade vanilla is the BEST!
Cooked Chocolate Frosting Ingredients
Texas sheet cake frosting is the bomb, you don’t even need to wash your pan from the cake! Simply toss your ingredients into the same pan, melt, stir, whisk until smooth!
- butter | see above so there isn’t any gnashing of teeth happening 🙂
- cocoa powder | same kind you used in the cake
- milk| but you can also substitute half and half or heavy cream as well
- vanilla | the best flavor in the world, nothing “plain” about it!
- powdered sugar | also called confectioners sugar, the powdery white sugar!
- mini chocolate chips | optional, but they add a nice touch
- chopped pecans | optional again, my son has tree nut allergies, sadly I cannot use them, but they are yummy!

What Size Pan is used to make the Best Texas Sheet Cake?
A full sheet pan is 18″ x 26″ which is enormous and most of us don’t have ovens large enough to fit one.
So technically speaking, what we are using is a half sheet pan which is 18″ x 13″, also called a baking sheet, but what I commonly use as a cookie sheet and have four or five in my kitchen.
A 10×15 inch jelly roll pan or a 9×13 baking pan may work. You will need to adjust the baking times since both pans are smaller and will take longer for the cake to bake through. Be careful with the jelly roll pan as it could overflow, you might want to spoon some of that batter into a square baking pan.
If it starts browning too quickly at the edges, simply place foil around the edges of the pan or lightly place a sheet of foil over the top. I have not make this cake in smaller pans, so please provide with caution.
Bake until the cake springs back when lightly touched or there are only fine crumbs on a toothpick when inserted.
HIGH ALTITUDE CAKE BAKING TIPS
Cakes can be finicky at normal altitudes, but the higher the altitude the more testy they become, here are my tips for high altitude baking, sometimes you need to try a recipe few times to figure out the best for your oven and altitude. This recipe was tested at 5280 feet above sea level (Mile High City).
- Decrease the double-acting baking powder or baking soda by one-quarter to one-half teaspoon for every teaspoon called for in the recipe, and add an extra egg, but do not over beat the eggs.
- Increase the liquid by three to four tablespoons for each cup liquid indicated.
- Decrease the sugar two to three tablespoons for each cup in the recipe.
- Increase the flour by one to two tablespoons for each cup called for. Increase the baking temperature about 25 degrees.
- Be sure to grease your pan extremely well and only fill ½ full as cakes like to stick more at altitude and will tend to rise quicker.
- Use an oven thermometer to make sure your oven is heating at the correct temperature.
Frequently Asked Questions

If not eating within 2-3 days, then yes, I would recommend refrigerating, but be sure to cover well with plastic wrap. Otherwise it should be fine covered on the counter.

Instructions
- For the Texas Sheet Cake
- Preheat oven to 350°F

- Pour into sprayed half sheet pan (13 x 18") and bake at 350° F for 20-25 minutes until it springs back lightly when touched. See notes for baking in different sized pans. Remove from oven and cool 5 minutes before pouring on frosting.
- Frosting
- About 10 minutes into baking time, start making the frosting.
- Using the same saucepan you made the cake batter in, melt butter over medium-low heat. Stir in cocoa powder to combine, remove from heat. Add powdered sugar, vanilla and milk stirring together until combined, then whisk until smooth.
- If desired, add pecans to the frosting directly, mixing to combine or sprinkle over the top of cake after frosting.
- Remove cake from oven and allow to cool 5 minutes on cooling rack, whisk frosting one more time, adding a bit of milk if it’s too thick, it should be pourable and still warm. Pour warm frosting over warm cake, spreading with spatula until covered.

Is there room in the bigger pans to put plastic wrap on without touching the frosting?
I’m not sure what you mean by bigger pans, but if you chill the sheet cake for 10-15 minutes before putting the wrap on or let it cool completely the frosting will form a natural crust.
Carolyn
I recently moved here to Colorado from the south, and I was so pleased to see one of mine long time recipes converted to high altitude. It came out absolutely perfectly, and my guests raved over it. I love how it comes together with ingredients from your pantry, and it is so fudgy and delicious. I will be following you for sure!
I love hearing this Carolyn, so appreciate the follow and hope you enjoy the dozens of other high altitude adjusted recipes on the blog!
