Moist, deep dark chocolate cake is topped with my favorite chocolate fudge frosting to make this gluten-free Texas Sheet Cake. My hubby requests this gluten-free chocolate cake for his birthday almost every year! It’s much easier to make than a layer cake so I happily oblige.
Chocolate cake is definitely in my Top 5 favorite desserts. This gluten-free Texas Sheet cake is one of my favorites! I’ve been making the regular version of this Texas Sheet cake for many years and was happy to see that it turns out just as delicious when using a good quality gluten-free all-purpose flour blend.
Gluten-free Texas Sheet Cake is the perfect potluck dessert. You make it in a huge rimmed sheet pan (15.5″x10.5″), also known as a jelly roll pan. This is the jelly roll pan I have and use, it even has a lid! I love having the lid so I can cover desserts like this without foil or saran wrap sticking to the top of the dessert.
This is the same pan I use for my gluten-free Pumpkin Bars with Cream Cheese Frosting so it gets a lot of use around here!
Because of the large pan, this makes a thin sheet cake. You can also cut the pieces small if you want to serve a large crowd, so I do that when bringing to a potluck. At home, we like them nice and big with a glass of milk or scoop of ice cream.
Notes on Ingredients for gluten-free Texas Sheet Cake:
- Gluten-free Flour: As always, I recommend using a good quality gluten-free flour blend that isn’t made of bean flours. I have had great success with the texture of this cake when I use Gluten free Mama’s Almond Blend or Gluten free Mama’s Coconut Blend, King Arthur Measure for Measure Flour, and also with Cup4Cup flour.
- Baking cocoa: In this recipe, I like to divide the total amount called for and use about 1/2 of dutch-processed, Hershey’s regular or Saco blend cocoa and 1/2 Hershey’s special dark cocoa. That is how I achieve a deep, dark brown to the cake and icing.
- If the gluten-free flour blend you use already has xanthan gum or guar gum in it, then omit the xanthan gum called for in this recipe.
Everywhere I bring this people can’t get enough and I always come home with an empty pan!
The frosting for this cake is sooo good – it tastes like fudge! It’s made simply with powdered sugar, cocoa powder, butter, milk and vanilla extract. I use a hand mixer for making the frosting.
I’ve also posted this recipe adapted as gluten-free chocolate cupcakes and as “gluten-free Love Cakes” for Valentines! Happy Baking!
Gluten-free Texas Sheet Cake Recipe:
Gluten-free chocolate cake that's ready to serve a crowd! Serve up slices of this gluten-free Texas sheet cake at your next potluck or party. As always, be sure to double-check your ingredients for gluten. For the cocoa powder, I like to use about 1/2 of dutch-processed or Saco blend cocoa and 1/2 Hershey's special dark cocoa. That is how I achieve a nice dark brown to my cupcakes and icing. The number of servings will depend on how big you want to cut slices of cake. If serving with ice cream and toppings, we cut a little smaller. If bringing to a potluck with a lot of desserts, we cut a little smaller. Gluten-free Texas Sheet Cake

You got it! I won’t admit how much of this sheet cake I ate this week!
Adele says
Definitely giving this a try! Not too many ingredients either plus it’s chocolate… Mmmm, melt!
Mary Renee says
Ok, I REALLY wanted to love this cake.
But, something went massively wrong and I’m not sure what!! 🙁
It was so thick and springy just as a batter. Is that normal?
Seriously, when I was mixing it, it kept growing up the mixers like a bad science experiment come to life. It was pretty comical. lol
I used a cup for cup flour that already contained xantham and as I had no buttermilk on hand, I did the regular milk with vinegar substitution. That was my only difference, but I don’t think it would make that much of a difference.
Yours looks fantastic and I really want to make it again. Any suggestions?
Michelle Palin ~ My Gluten-free Kitchen says
Mary,
The only two times I’ve had something like what you are describing happen, I stood there shaking my head wondering what in the world?! Then I tasted the batter and realized I had completely forgotten the sugar! If that happens, you have to toss it and start over. Could that have been what happened to you? It is important that the sugar is in there with the other dry ingredients when you add the liquid. The sugar will liquify then helping make a more runny batter.
The only other thing is if you used a flour blend with coconut in it. The coconut flour really absorbs the liquids and you end up with a much more solid batter. It still turns out okay once baked though.
Hope you’ll try it again Mary!
Mary Renee says
Nope, I added the sugar. The taste was fine, the consistency was just off. The flour I use is a rice flour/cornstarch/tapioca mix. It’s done well with all the other breads and sweets I’ve made.
I did realize that I made a total rookie mistake and used baking powder instead of soda. I’m hoping that that is the major factor.
I’m going to make a half batch here in a little bit. I’ll let you know if that changes anything. 🙂
Jen G says
I had the same problem. I used my own brown rice, tap and potato starch mix and also used vinegar to sour my milk. It tastes OK but it’s a little gummy/chewy. I was wondering if it could be too much xanthan gum but now I’m wondering if it has something to do with the vinegar.
Norma Jean Stapleton says
When I bake with a rice flour blend , it tends to be more gummy,chewy also.
Linda billingsley says
Do you have a yellow cake gf recipe? Thank you.
Judy says
We have always loved this cake for many years. Especially with chopped nuts on top! Thank you for sharing this! Recently our diets have changed and now I need to know if I can substitute coconut palm sugar for the regular sugar?
Michelle Palin ~ My Gluten-free Kitchen says
Judy,
Chopped nuts on top is totally great for this!
I haven’t tried using coconut palm sugar in this recipe, but I do think it would work. Give it a try and let me know!
Susan says
I’m not an expert here but I’ve baked with all the flours you mentioned. The almond flour gives the cake a sponge like texture. I have a wonderful coconut cake recipe with white chocolate and whipped cream frosting that uses the almond flour I believe that’s what went wrong with some of the cakes. I use King Arthur’s gluten free flour and never have a problem with my cakes turning out. If a recipe calls for coconut flour I’d advise you to use it at first then see if it turns out to your liking. I can even see it in the photograph that’s pictured of the cake. I don’t like baking with the dutch processed chocolate unless it’s called for in a recipe. it can have a different taste and look. I can’t wait to try this recipe. I’ll try it and let you know how it turns out. I have to wait until I have a big event though. Too much cake for me. I’d eat too much of it.
Liz says
I have made this cake twice now with gluten free bisquick and it turns out amazing. I’ve used both sour cream and buttermilk and both are fabulous. It is my favorite gluten free cake. It is just like my Grandma used to make. I’d like to cut back on the sugar but haven’t been brave enough to try it yet since everyte me I make it, it is for a party.
Lori Kaumans says
Could you use Swerve or erythritol instead of sugar?
Betty says
Ah-mazing! Absolutely awesome cake. Makes a huge amount but my family is t complaining 🙂
Catherine Davis says
Hi! I am looking for a recipe to use for a banquet and I have a quick question. Can you use Bob mill’s GG Flour? Will it turn out well? If so, this is definitely the recipe for me.
Catherine Davis says
Or even coconut flour?
Michelle Palin ~ My Gluten-free Kitchen says
Catherine, I’m not crazy about the performance of Bob’s Red Mill’s flour, and also don’t recommend it because it isn’t certified gluten-free. Good flour blends that should work well here are Gluten Free Mama’s, Cup4Cup, or Pamela’s. Definitely don’t use coconut flour or a blend with coconut flour, as it really absorbs the liquids and will affect the texture.
I recommend baking a test cake before the event you need to bring it to so you can make sure the blend you use works fine for it!
Kay-M says
I used the Bob’s Red Mill flour (1 to 1 – with the blue label) – and EVERYONE (even those that eat gluten items all the time)was raving at how good it was. My granddaughter is gluten-intolerant (not celiac), and LOVES this cake – even without the frosting!! This will be my go-to recipe from now on!!! THANK YOU so much for posting this!!!!!!!
And a great place to buy this flour is at Sam’s Club. I only pay $8.48 for 5 pounds!!
Caroline says
I’m always skeptical of GF recipes that boast of being as good as regular flour recipes, BUT this was really good! I used King Arthur GF All Purpose Flour. I made one batch as written and one with bittersweet chocolate chips added into in the cake batter. Both were really good, but in a side by side taste test the one with the chocolate chips edged out the original. I took this to a big family party where no one but myself was GF and everyone loved them! The only thing I might try next time is reducing the sugar a little. Thanks for sharing!!
Laura B says
I used King Arthur Flour’s Measure for Measure, which is my go to for all GF cooking and baking. Turned out perfectly!
Cheryl says
But where’s the cinnamon? I know some people have nut allergies, but where’re the nuts? I know, I know, I can add them but that was always my favorite part about the Texas sheet cake of my long ago youth ????
Michelle Palin ~ My Gluten-free Kitchen says
Yes, feel free to add cinnamon and nuts!
Laura Jolly says
Can you make this with almond flour?
Michelle Palin ~ My Gluten-free Kitchen says
No almond flour wouldn’t work as a straight substitution. If you are looking for recipes that only use almond flour, I would google almond flour chocolate cake. Probably some paleo ones will suit you most.
Sarah Levine says
At the beginning, you say that you use a 13″x18″x 1″ jelly roll pan, but the recipe says 15″x 9″x 1″. I can only find the larger size, so hopefully that’s correct.
I have made this before, and it was amazing, but I forget what I used! Along the same vein, can this be made in 9″x 13″pan?
Thanks,
Sarah
