Texas sheet cake is basically the dessert equivalent of comfort food – unpretentious, satisfying, and guaranteed to make everyone happy. Unlike fancy layer cakes that require engineering degrees to assemble, this beauty gets mixed in one bowl, baked on one pan, and frosted while still warm.
The magic happens in that last step. When you pour hot frosting over hot cake, something incredible occurs – the frosting partially melts into the surface, creating this fudgy, almost brownie-like top layer that’s absolutely irresistible.
What makes this version special? A touch of buttermilk that keeps everything incredibly moist, and toasted pecans in the frosting that add just enough crunch to make each bite interesting.

What You’ll Need to Make It
For the Cake:
• 2 cups all-purpose flour
• 2 cups granulated sugar
• 1 teaspoon baking soda
• 1 teaspoon salt
• 1 cup unsalted butter
• 1 cup water
• 1/4 cup unsweetened cocoa powder
• 2 large eggs
• 1/2 cup buttermilk (or make your own: 1/2 cup milk + 1/2 tablespoon vinegar)
• 1 teaspoon vanilla extract
For the Frosting:
• 1/2 cup unsalted butter
• 1/4 cup whole milk
• 1/4 cup unsweetened cocoa powder
• 4 1/2 cups powdered sugar
• 1 teaspoon vanilla extract
• 1 cup chopped pecans
Ingredients Notes: Don’t stress if your eggs are cold – just crack them into a bowl of warm water for 5 minutes while you prep everything else. For the pecans, toss them in a dry skillet for 3-4 minutes until they smell amazing. Trust me on this step – it makes a huge difference. And yes, you need to sift that powdered sugar unless you enjoy lumpy frosting (you don’t).
Step-by-Step: From Batter to Frosting
➲ Get your oven ready.
Preheat your oven to 350°F and grease an 18×13-inch sheet pan. The pan size is key here, too small, and your batter will overflow; too large, and your cake will end up thin and sad. Getting this right sets you up for a perfectly baked, luscious cake.
➲ Mix your dry stuff.
In a large bowl, whisk together flour, sugar, baking soda, and salt. Take a moment to break up any lumps, this ensures a smooth, even texture in your finished cake. Think of it as laying the foundation for your masterpiece.
➲ Make the chocolate mixture.
In a medium saucepan, combine butter, water, and cocoa powder, then bring to a rolling boil over medium heat. Keep whisking constantly so the cocoa stays silky and doesn’t clump. Once smooth and glossy, you’ve reached chocolate perfection, ready to meet your dry ingredients.
➲ Combine everything.
Pour the hot chocolate mixture into your bowl of flour mixture. Stir gently with a wooden spoon; it may look a little rough at first, and that’s perfectly normal. As you keep mixing, it will come together into a rich, luscious batter, ready for the oven.
➲ Add the good stuff.
Now it’s time for the magic! Beat in the eggs one at a time, making sure each is fully incorporated before adding the next. Then, stir in the buttermilk and vanilla until the batter is smooth and glossy. Be gentle, overmixing can make your cake dense and tough, and we’re going for soft, tender perfection here.
➲ Bake it up.
Spread the batter evenly in your prepared pan. Don’t worry if it looks a bit thin, that’s normal. Slide it into the oven and bake for 18-22 minutes. To test for doneness, poke with a toothpick: it should come out with just a few moist crumbs. If it comes out completely clean, the cake may be overbaked, so keep an eye on it.
➲ Start the frosting 5 minutes early.
While your cake is finishing up in the oven, get a head start on the frosting. Using the same saucepan (less cleanup, more chef-style efficiency!), combine butter, milk, and cocoa powder and bring to a gentle boil. Keep whisking so the mixture stays smooth and glossy, this is the base of your rich, chocolatey topping.
➲ Finish strong.
Once off the heat, whisk in powdered sugar, vanilla, and those toasted pecans for an extra crunch and nutty depth. Pour the frosting over your cake the moment it comes out of the oven, the heat helps it spread and seep into every corner, creating a luscious, glossy finish. Stand back and admire the magic as it sets while still warm.
Smart Shortcuts & Tricks
❃ Timing is everything here. Both cake and frosting need to be hot when they meet. This isn’t just for convenience – the heat creates that signature texture where the frosting partially soaks in while still maintaining a fudgy top.
❃ Don’t second-guess the doneness. When that toothpick comes out with a few moist crumbs, pull it. The residual heat will finish the job, and you’ll end up with perfectly moist cake instead of chocolate cardboard.
❃ Make it a day ahead if possible. This Texas sheet cake is good fresh, but it’s absolutely phenomenal the next day. The flavors meld together and everything gets more moist and fudgy.
❃ Cut with confidence. Use a sharp knife and wipe it clean between cuts for neat squares. Or don’t – rustic works too.
❃ Store it right. Cover with foil or plastic wrap and keep at room temperature. It’ll stay perfect for 4-5 days, assuming it lasts that long.
Texas Sheet Cake Q&A
➲ Can this be made in a smaller pan for fewer people?
Absolutely. Halve everything and use a 9×13 pan. Bake for 15-18 minutes and watch it carefully since smaller pans can go from perfect to overbaked quickly.
➲ What if don’t have buttermilk?
The milk and vinegar substitute works perfectly. Let it sit for a couple minutes after mixing – it’ll get thick and tangy just like store-bought buttermilk.
➲ How do know if the frosting consistency is right?
It should pour easily but not be watery. Think thick cream. Too thick? Add milk a tablespoon at a time. Too thin? More powdered sugar, 1/4 cup at a time.
➲ Can substitute the pecans?
Walnuts work great, or try toasted coconut for something different. Going nut-free? Mini chocolate chips or just skip them entirely – the cake is still fantastic. #Texas Sheet Cake #easy Texas Sheet Cake #Texas Sheet Cake recipe
