This ultra-moist Texas Sheet Cake has been my secret weapon for potlucks and family gatherings for years. The simplicity of mixing everything in one pan and pouring warm frosting over hot cake creates an irresistible fudgy texture that disappears faster than I can serve it.
I first made this cake for my son's baseball team celebration, and it vanished within minutes. Now it's requested at every family reunion, and I've learned to make two batches if I want leftovers!
Ingredients
- Butter: creates a moist, tender crumb and adds richness to both cake and frosting
- Water: thins the batter for the signature sheet cake texture
- Unsweetened cocoa powder: provides deep chocolate flavor without excessive sweetness
- All purpose flour: gives structure while maintaining softness
- Granulated sugar: balances the cocoa bitterness perfectly
- Baking soda: provides the perfect rise and tender texture
- Salt: enhances all flavors and balances sweetness
- Eggs: bind ingredients and add structure to the cake
- Buttermilk: adds tang and creates incredible moistness
- Vanilla extract: rounds out the chocolate flavor beautifully
- Powdered sugar: creates a smooth frosting that sets perfectly
- Pecans: add delightful crunch and traditional Texas flavor
Step-by-Step Instructions
- Prepare the pan:
- Thoroughly grease a 15x10 inch jelly roll pan or sheet pan. The cake batter will be thin, so make sure all corners are well greased to prevent sticking. Preheat your oven to 350°F to ensure consistent baking.
- Create the chocolate base:
- In a medium saucepan over medium heat, melt the butter completely. Add water and cocoa powder, stirring constantly until the mixture comes to a rolling boil. This process blooms the cocoa flavor and creates the signature base. Remove from heat immediately to prevent scorching.
- Mix dry ingredients:
- In a large mixing bowl, thoroughly whisk together the flour, sugar, baking soda, and salt until no lumps remain. This ensures even distribution of leavening and sweetness throughout the cake.
- Combine wet and dry:
- Pour the hot cocoa mixture over the dry ingredients and stir gently but thoroughly. The heat from the liquid helps begin the cooking process and creates the unique texture. Make sure all flour is incorporated.
- Add remaining wet ingredients:
- Add eggs one at a time, mixing well after each addition. Stir in buttermilk and vanilla, mixing until the batter is smooth and glossy. The batter will be thinner than traditional cake batter.
- Bake to perfection:
- Pour batter into the prepared pan, using a spatula to spread it evenly into corners. Bake for exactly 20 minutes, then check for doneness with a toothpick. It should come out with a few moist crumbs but not wet batter.
- Make the frosting:
- During the last 5 minutes of baking, prepare the frosting. Melt butter in a saucepan, then stir in cocoa powder until smooth. Add milk, then remove from heat and gradually stir in powdered sugar and vanilla until silky smooth.
- Apply the frosting:
- Pour warm frosting over the hot cake immediately after removing from oven. Work quickly to spread it evenly across the surface before it begins to set. Sprinkle with pecans if using, pressing them lightly into the frosting.

The warm frosting poured over hot cake is what makes this recipe truly special. My grandmother taught me this technique, saying the heat creates that signature fudgy layer between cake and frosting that you simply cannot achieve with traditional cold frosting methods.
Make Ahead Tips
This Texas Sheet Cake actually improves with time! The flavors deepen and the texture becomes even more perfect when made a day ahead. To keep it fresh, simply cover tightly with plastic wrap once completely cooled. The cake stays moist and delicious at room temperature for up to three days. For longer storage, cut into portions and freeze individual slices for up to two months.

Perfect Variations
While traditional Texas Sheet Cake is chocolate, you can create delightful variations with minimal adjustments. For a white Texas Sheet Cake, omit the cocoa powder from both cake and frosting, and add an extra teaspoon of vanilla. For a peanut butter version, add 1/2 cup peanut butter to the frosting while it's warm. My personal favorite twist is adding 1 teaspoon of cinnamon to the dry ingredients for a Mexican chocolate inspired flavor that adds wonderful warmth.
Serving Suggestions
Texas Sheet Cake is perfect on its own, but transforms into a showstopping dessert when served warm with a scoop of vanilla ice cream. For casual gatherings, cut into larger squares; for more elegant presentations, cut smaller rectangles and serve with fresh berries and a mint sprig. This cake pairs beautifully with coffee or cold milk, and makes an unexpected but delightful breakfast treat the next morning!
The History Behind The Cake
Texas Sheet Cake earned its name not only from its size but its popularity across the Lone Star State since the mid-1900s. Originally created as a practical dessert for large gatherings where serving individual layer cakes would be cumbersome, this style of cake became a staple at church socials, potlucks and family reunions throughout Texas. The combination of pouring warm frosting over hot cake is believed to have originated during times when quick cooling was necessary before refrigeration was common.
