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 Sheet Cake that she passed down to my mom and could totally be from Texas given the size.

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’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. 😉

My mom grew up eating this easy chocolate sheet cake and it made an appearance at my house every holiday season growing up. It’s easy to make, sets up perfectly, stays moist, and it feeds an army. Isn’t that exactly what you need around the holidays, easy to make food that feeds a ton of people? Plus, just wait until you smell all of that chocolate cooking, you’ll thank me. Promise.

  1. Do you use all purpose flour or cake flour?

  2. hi dear i want ask what the replace for Shortening

  3. Looks wonderful.  What size pan are you using?

  4. Is the nutrition information accurate? Over 7000 calories!!! Yikes!!!

  5. Texas Sheet Cake!!!
    I’m gonna have to see how this one turns out. I have a huge family so anytime the family got together my grandma would make it and anytime we had a potluck after church service. The only thing my grandma would do differently is add some chopped walnuts and or cherries (around the holidays).

  7. I am 72 yrs of age and this cake has been around for a long time, I’d say as least 30 yrs. We called it Texas Sheet Cake.It was the frosting that everybody raved about.

  8. This cake sounds fabulous! I was wondering about substituting the margarine for butter and the water for coffee…your thoughts?

    • Hi Christine, I’ve used butter quite a bit and while I have to admit that it doesn’t come out as moist, I love the butter flavor. I would probably do half water, half coffee to start with. It should enhance the chocolate flavor but you want to make sure that it doesn’t take away from that typical sheet cake flavor. 🙂

  9. Could you cook it in a 11×13 pan? I don’t have a pan the size you said to do it in

    • Unfortunately this cake really is meant for a cookie sheet, but you could always lower the temperature a little and try baking it longer however you would have to just watch it as I don’t know the baking time since it would be a thick cake.

  10. Let me first say the frosting is AMAZING!!! Everyone loved it. That being said, the cake is not good. For starters, the cinnamon throws everything off and I wish I had omitted it. It’s also too sweet. I would reduce the amount of sugar by at least 1/4 cup, if not 1/2. Lastly, (and my oven temperature is correct), I would reduce the cooking time by a couple of minutes. The cake was very dry.

    The frostng will be wonderful on my next batch of brownies though.

    • Hi Katie,
      You shouldn’t be able to taste the cinnamon as it’s just to enhance the chocolate. It should give a little something to the cake, but not be detectable. As for the cake, I would test the oven as this is a very moist cake (I’m a bit of a weirdo about that. I detest cakes even a little dry). I’m sorry you didn’t enjoy it.

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

  12. 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.

  13. 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!

  14. When you say soda do you mean baking soda??

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

  16. 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.

  17. 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!

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

  19. 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 🙂

  20. 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!
