The BEST Texas Sheet Cake
Why is it called Texas Sheet Cake?
It’s not known why chocolate sheet cake is often referred to as “Texas sheet cake.” I like to think it’s because it’s a cake the size of Texas. 🙂
This chocolate cake recipe is made in a sheet cake pan, which is where it gets the name, “sheet cake.” A sheet cake is any cake that is made in a large rectangular pan known as a sheet pan or jelly roll pan.
What size pan to make sheet cake:
Texas sheet cake recipes usually bake in a baker’s half-sheet pan that’s 18×13” inch. I prefer this type of pan because it results in a thinner cake with a thin layer of chocolate frosting, and it’s perfect for feeding a crowd.
You can bake Texas sheet cake in a 9×13” pan, but increase the baking time to about 30-35 minutes.
What’s the difference between Sheet Cake and Regular Cake?
The primary difference between sheet cake and regular cake is the size of the cake pan. Sheet cake is made in a sheet cake pan which is a shallow, large pan. Regular cake is usually made in a 9×13 baking dish or, for a double layer cake, it’s made in two 8-9” round pans.
How to make Texas Sheet Cake:
- Add to saucepan: water, butter, and cocoa powder and bring mixture to a boil.
- In a bowl: mix together the flour, sugar, baking soda, and salt.
- In another bowl: mix together the sour cream, eggs and vanilla. Add sour cream/egg mixture to the flour mixture and mix until combined.
- Combine the batter. Once the chocolate mixture in the saucepan in boiling, remove it from heat and pour it into the batter. Mix until combined and no lumps remain.
- Pour into sheet pan. Pour mixture into prepared pan and smooth with a spatula to make sure it is dispersed in an even layer.
- Bake. at 350°F for 15-20 minutes or until set (mine is usually done around 15 minutes).
How to make Sheet Cake Frosting:
- In a saucepan: Add milk, cocoa and butter; bring mixture to a boil.
- Stir in: powdered sugar. I like to beat the mixture with my hand-held mixer to get rid of any lumps.
- Pour over cake. Pour the hot mixture right over the hot cake. Use a spatula to spread it evenly over the cake. Allow frosting to set for about 10 minutes before eating.
Do you need to refrigerate Texas Sheet Cake?
You don’t have to, but it will last better and longer if stored, covered, in the refrigerator. If you live somewhere warm and humid, it’s especially best to store it in the fridge.

This cake is amazing! My husband said it is the best cake ever! I took this to our family’s Thanksgiving dinner and everyone who tried it loved it! This will be a go to recipe when I need to take a dessert somewhere. My mom used to make this when I was young and I didn’t have her recipe so when I saw all the great reviews on this recipe I knew it was the one to try. I just made a second one to take to another dinner tomorrow! My mom will be there and I can’t wait for her to try it. She told me the story of how when she was young and stayed all night with her friend Margaret her mother would make a Texas Sheet Cake and she couldn’t more than get it out of the over before they were begging for a piece. I hope this brings back many great memories for her like it did me. Thanks for the amazing recipe.
Never even heard of a Texas sheet cake until I saw this recipe on Instagram. Wow ! What a simple cake but it is just so so so so good. The cake… the frosting… I’ve never liked such a simple chocolate cake before. SO good ! Making it again after just a few days 🙂
This is the go-to recipe I use for Texas Sheet Cake! I’ve made a few and this one with sour cream is just the BEST! We are gluten free and I have had absolutely no trouble substituting a gf all-purpose flour and keeping the rest of the recipe the same. I’ve used walmart brand gf flour, krusteaz, king arthur, and a homemade better batter knockoff flour and all of them have worked just fine! Thanks for a great recipe!
Thank you for this GF comment! 🙂
Good morning, I tried this recipe and was out of sour cream, so I substituted with whipped cottage cheese and it turned out absolutely wonderful! My fiance says it’s the best cake he’s ever eaten. Thanks and we’ll be trying more of your recipes in the upcoming Days. Hope you have a blessed Day!!
Sooooo delicious! I don’t change a thing about the recipe and it’s a hit every time.
Can̈ I sub honey for sugar?
I love this recipe! A coworker shared it and it’s a go to now.
I’m wanting to try making a peanut butter sheet cake, but don’t know where to start. Any ideas??
Easy & delicious!
Made this several times and love it! Thinking of trying it as a strawberry flavored cake…. Anyone try yet? Suggestions? Was thinking maybe strawberry Quik instead of cocoa? Maybe gelatin? Or maybe puree?
Just made this today!! So excited to see how it tastes. It looks beautiful! Thank you for the recipe
So delicious! I had trouble trying to halve finished cake for 2 birthdays- did not work out but every crumb was eaten! Is it possible to make this in a 9×13 with a longer bake time?
Thank you!
Surprisingly, it was just, well, fine. Wouldn’t say it’s the best ever – not as good as the Texas sheen cake my mom used to make, and I realized It’s because the lack of cinnamon. I remember her frosting a little darker – perhaps dark chocolate cocoa powder? I think if I were to make this again, I would be sure to use the highest quality dark cocoa powder available, and add the cinnamon. That said, I don’t think I’d make this again because there are so many other cakes I prefer for the effort of clean-up. So sorry.
Absolutely delicious!! 🤤 Thank you for the recipe!
