Everything’s bigger in Texas. And while I’m not from nor do I live in Texas it is hands down the state with the most pride ever. EVER. When I lived there for a brief moment I discovered that every license plate, house, doorstep, etc. bears the state or the state flag. Good mercy. And yet, I loved it. In fact, I would love to move there.

I’m going to enjoy Grandma’s chocolate cake that she passed down to my mom and could totally be from Texas given the size. Just look at it…it’s absolutely perfect…

The Best Cooked Chocolate Frosting

I hate to admit this, but I could drink cooked chocolate frosting. Actually my favorite part is after you’ve frosted the cake and the saucepan has frosting setting up in it. I lick it. I full on dip my finger and lick the pot clean. Don’t judge. It takes this cake over the top and through the roof!

It’s so unbelievably good. And Creamy. And warm. Oh, it’s so warm and perfect. I know, you’re all confused. The frosting is made stove top and oh my gosh, it’s so delicious. I just pace while my mom makes it, and then I steal that spatula as fast as I can. I totally hate when she uses every last bit of frosting. Such a waste. 😉 See section below for making the cooked chocolate frosting of the gods.

How to Make Cooked Chocolate Frosting

You might think that something so good has to be difficult to make. Nothing could be more untrue when it comes to this frosting. While the cake is baking, you can get to work on this easy cooked chocolate frosting:

  • Grab another sauce pan, or quickly clean the one you just used for the cake, and add the margarine, cocoa and milk and bring them to a soft boil over medium heat.
  • Add the powdered sugar and vanilla to the cocoa mixture and whisk everything together until smooth.

Your cooked chocolate frosting is done! Let the finger dipping and licking begin….errrrr, I mean, I never would do that! Spread the frosting onto the cake while both the frosting and cake are still warm.

Now cut yourself a piece the size the Texas and you’ll be the happiest camper that ever has been! This is the classic chocolate Texas sheet cake you know and love! Enjoy it for holidays, family reunions, birthdays or just an average Wednesday…everyone needs chocolate on an average Wednesday!

    I got my copy of the Texas Sheet Cake from a Texas lady named Sherene. Wonderful cake!

    1. Sweet Basil says:

      Well that is definitely straight from a Texas source!

  2. DYDY says:

    I am from a 7 generation Texas family and this recipe is the real deal! I have seen other versions that didn’t get it right. The only thing we (me, Mother, Grandmas) do differently is to add tons of pecans to the icing. The cinnamon does something to enhance the flavor of the chocolate but when you are eating it you have no idea it’s in there.

    1. Sweet Basil says:

      I couldn’t agree more! That cinnamon is totally undetectable but to skip it just ruins the whole thing. I’m so glad we got this one right!

  3. Belinda says:

    All the elderly ladies at my church growing up would make this for church suppers and it went fast that’s why so many of them made the same dessert. Great memories and great reason to make this cake!

    1. Sweet Basil says:

      I love when a recipe comes with great memories!

  4. Dawn says:

    When you say soda do you mean baking soda??

    1. Sweet Basil says:

      Hi Dawn, Yes, baking soda

  5. Tina sokia says:

    Thanks, I will try this out. My family loves chocolate cake.

    1. Sweet Basil says:

      It’s such a classic. Hope you love it!

  6. Lisa I says:

    This reminds me of the cake that my former boss, a born-and-raised-and-never-left Texan, made. She called it a Texas sheet cake and she would make it about once a month on a Monday and there was never a single scrap left. I miss her and boy, do I miss that cake. I’m not from Texas, btw, but I got here as fast as I could.

    1. Sweet Basil says:

      It’s so simple, but it really is so good! And I love that food so quickly reminds us of people!

  7. Alicia says:

    I never heard of this before and I lived in Texas my whole life lol but now with my birthday next month I want to eat this 🙂 Thank you for the recipe!

    1. Sweet Basil says:

      Just wait until you have that warm frosting. It’s heaven! And what day is your birthday? Our anniversary is the 19th!

  8. Denise says:

    Does anyone know if this can be made in a regular 9 X 13 cake pan? If so how long would you bake it?

  9. Alyson - Lift, Bend, Bake says:

    Texas Sheet Cake is the BEST! The first time I had it, I’d never heard of it.. and come to think of it, now that I actually live in Texas it seems only appropriate I should make it 🙂

    1. Sweet Basil says:

      Heck yes you should! And I’m jealous you get to live in Texas!

  10. Jamie@Milk 'n' Cookies says:

    Hi Carrian! Just found your blog through Roxana’s Home Baking! I cannot wait to try your recipe for Texas sheet cake. I’ve been making a recipe for Texas sheet cake that I found in a big-name cookbook, and it’s always been delicious. But I have a feeling that your recipe would leave that one in the dust. I’ll definitely be trying this soon!

    And I had to chuckle at your assessment of Texan state pride. I like in New Jersey — another place with a lot of state pride. When I first moved here, I saw people wearing shirts that said “New Jersey — only the strong survive” and I thought it was a bit ridiculous (seriously, why is everyone here so dang PROUD of being from New Jersey?!). But now I totally get it — and love it!

    1. Sweet Basil says:

      lol! Isn’t it so funny?! Washington was definitely not like that. Everyone was too busy staying dry, making granola or eating salmon 😉 jk, kinda
