Vegan and Texas are not words you often see side-by-side. Maybe unless you’re in Austin, which I will be next week. More about that in a minute.

But first let me tell you about this cake. Shawn and I went to spend some time with friends over the holiday weekend. Oh, what fun we had. I like to share some of my favorite vegan meals when we show up at someone’s door so I brought my tasty Vegan Broccoli Salad and Vegan Texas Sheet Cake.

Let’s just say there were more than a few ooh’s and ahhh’s which made me more than just a little happy. I didn’t break into my happy dance – I was trying to be a respectable dinner guest – but I thought about it!

I’m going to Austin next week. I’m so excited! Of course, it’s never fun leaving friends and family behind, but sometimes it’s a necessary part of a job. It’s my first time to go to this fair city which so far I’ve only experienced via Austin City Limits. If that’s any indication of what to expect, it’s a very cool place to be.

Which is, of course, what I’m ALL about. Total 100% coolness.

Except for when I’m being dorky and breaking into a happy dance over a cake.

But when you make a cake that tastes this good, and it’s vegan, and the fact that it’s vegan causes your non-vegan friends to raise an eyebrow and say with complete and utter surprise, “This is really good. I mean really good” then getting all happy about it is completely understandable.


That’s happy dance talk right there!

Of course, I decided to save that little happy jig until after we left. No reason to add fuel to their “vegans are weird” theory.

Trying to be cool can be so exhausting! It’s like wearing my suit all day at a meeting when all I really want to be wearing is my yoga pants.

See? Lounging around in yoga pants. That’s either really cool…or really vegan. I can’t decide. Maybe both?

Why You’ll Love Vegan Texas Sheet Cake

My mom makes this cake for our annual family summer gathering. We have this annual fest at my sister’s house. She and her husband live out in the country so they get fireworks and we bring our Vegan Potato Salad, and we have a feast!

The best part comes after dinner when they pull out the desserts. My mom makes a regular version for everyone else and also this vegan Texas sheet cake for me! Of course, Share it with Shawn and Adee and Joe too.

Vegan Texas sheet cake creates a very dense, moist cake with a creamy chocolate frosting infused with pecans.

How to Make Texas Sheet Cake

It’s relatively easy to make this vegan Texas sheet cake…and even easier to eat!

The ingredients are:

  • vegan butter (or coconut oil)
  • cocoa powder
  • water
  • all purpose flour
  • sugar
  • salt
  • baking soda
  • soy buttermilk (made with plant-based milk + apple cider vinegar)
  • tofu
  • vanilla extract

If you want to make this cake a bit healthier, you can use whole wheat pastry flour. It will add some fiber to this recipe and I have found using this flour doesn’t make it quite as dense as using regular whole wheat flour. In addition, you can use coconut sugar to add a little more healthy to this recipe too.

For my Vegan Chocolate Sheet Cake, I actually used half and half peanut butter and vegan butter. It works perfectly and doesn’t add too much of a peanut butter flavor. I like using nut butters as the fat in my recipes, and finding the right balance is important.

Follow the instructions to make the frosting for this vegan Texas sheet cake, but the most important tip is to put the frosting on while the cake is still hot from the oven. I know. It’s counterintuitive, but it helps that frosting seep into the cake, adding sweetness and tenderness throughout.

And look at that shiny coating on top of the frosting! It comes from being applied while the cake is still hot!

For the Moist Chocolate Cake:

  • 1 cup vegan butter
  • ¼ cup cocoa powder
  • 1 cup hot water
  • 2 cups all-purpose unbleached flour
  • cups sugar
  • ½ teaspoon salt
  • 1 teaspoon baking soda
  • ½ cup soy buttermilk soy milk mixed with 1 teaspoon apple cider vinegar
  • ½ cup whipped firm tofu or extra firm, place tofu in a blender or food processor and pulse until smooth
  • 1 teaspoon vanilla

For the Chocolate Pecan Frosting:

  • 1 stick dairy-free margarine 1/2 cup
  • ¼ cup cocoa powder
  • 2– 3 tablespoons soy milk
  • 1 teaspoon vanilla
  • 3– 4 cups powdered sugar
  • ½ cup chopped pecans plus more if you’d like to put on top for a nice touch


  • Heat your oven to 350F. Prepare your sheet cake pan by giving it a quick spray of vegetable cooking spray.
  • In a saucepan, melt the butter over medium heat. Add the cocoa and stir until well combined. In a separate, small sauce pan, heat the water until it’s good and hot. Add the hot water, stir, and bring that mixture to a boil for 20-30 seconds. Then remove from heat.
  • In a mixing bowl, combine the flour, sugar, salt, and baking soda.
  • In a separate, smaller bowl combine the soy buttermilk, whipped tofu, and vanilla and stir well. Set aside.
  • Now comes the fun part. Pour the hot chocolate mixture over the flour mixture and stir well. Then fold in the soy buttermilk mixture and stir until everything is well-combined. Pour the batter into your prepared cake pan. Bake for 20 – 25 minutes.
  • We will be icing the cake while it is still warm so go ahead and make the frosting while the cake is baking. Melt the margarine in a saucepan (I used the same one from the cake…didn’t even bother to rinse it out since the ingredients are so similar) over medium heat. Add the cocoa. Is this sounding familiar?
  • Remove from heat and add the soy milk and vanilla. Stir until combined. Now add the powdered sugar. I add it one cup at a time, giving it a good stir between each cup to work out any lumps from the powdered sugar and to make sure I get the right consistency with the frosting. Add the chopped pecans, stir together, and then sit by the oven waiting for the cake to finally get done. It may add some drama if you act annoyed at how long it’s taking. The kiddos will laugh if you throw in a few exasperated facial expressions too.
  • Once the cake is done, remove it from the oven and pour the prepared frosting evenly over the still warm cake. Let the heat help you spread that frosting out all the way through from the far corners of the cake. You want every bite to know there’s frosting involved. And pecans. Make sure those are evenly distributed as well. Or add some finely chopped pecans to the top to really wow your guests!


I use what is technically referred to as a “half” sheet cake pan, in that it is 12″ wide X 16″ long by 2″ deep.

This is a perfect weekend cake so why not give it a try tonight! Enjoy!
