Texas Sheet Cake beats them all, it truly is the best cake. And as an added bonus it’s a cake I can make, from scratch, that’s always a hit! Plus it’s so big that taking it to a party or sending it somewhere for snacks means there’s enough to go around!

Texas Sheet Cake

I’m pretty well known for my Texas Sheet Cake Cookies but now lookout, I’m making the cake too! And who wouldn’t? It’s kinda perfect. Super soft and tender, and coated with a chocolaty icing!

Texas Sheet Cake is the kind of cake you make straight out of the pantry too. You don’t need any special supplies, you don’t even need chocolate, just cocoa powder! So when life hands you a reason to make cake, you can make it easier!

Texas Sheet Cake is WEIRD too

I mean you BOIL water and butter together to make this thing. It kind of seems like an impossible cake recipe. But then, in the end, it’s one of the most tender cakes I’ve ever made. Or eaten.

And the icing? You pour it over the hot cake, while it’s still hot as well. Then you just leave it to see up. Omgosh the things that happen when you pour hot icing on the hot cake, we’re talking some weird almost third layer in there where the cake and icing meet. You just need to try it out for yourself and see!

If you’re like me and you want to read more about the sheet cake and their history check out this article about them. And then there is this article where it’s called a Sheath Cake, which I also found interesting.

A Cake I Can’t Screw Up!

Believe me, I have made a lot of bad cakes in my life. It’s probably my biggest disappointment as a baker. Especially as the baker behind the GBBO Bake-Along Group on Facebook. Their own leader can’t make a cake to save her life until NOW that is!

About your Texas Sheet Cake:

  • you will need a sheet pan that is 18×13 inches, with sides at least an inch tall
  • do NOT grease your pan, it doesn’t need it!
  • I made this a Nut Free Texas Sheet Cake because I don’t like nuts in icing BUT if you like nuts, chop up 1/2 cup of pecans and toss them in the icing
  • be sure to sift the powdered sugar or at least run it through a sieve to get rid of the lumps or you will have lumpy bumpy icing

  1. I’m glad to see the salt in this recipe. I see so many versions with absolutely no salt at all. Those always taste flat to me. I always add some salt if I get one of those salt free recipes.

    • Right?? So many things taste so much better with a dab of salt, including this Texas Sheet Cake! <3

  2. Hi,
    I guessed a teaspoon of vanilla in the cake recipe. Vanilla is missing from cake ingredient list.
