How to Make Recipe

To make a Texas Sheet Cake, start by preheating your oven to 350°F (175°C) and greasing a sheet pan. In a large mixing bowl, whisk together flour, sugar, baking soda, and salt. These dry ingredients form the base of your cake.

Next, in a saucepan, combine butter, vegetable oil, cocoa powder, and boiling water. Stir the mixture until the butter has melted and everything is smooth. This hot chocolate mixture is then poured directly into the dry ingredients. Stir well to ensure a thick, chocolatey batter forms. Add in the buttermilk and lightly beaten eggs, mixing until the batter is silky smooth. Pour it into your prepared sheet pan and bake for about 20 minutes, or until a toothpick inserted comes out clean.

While the cake bakes, prepare the frosting. In a saucepan, melt butter along with cocoa powder and milk. Stir until well combined and smooth. Remove from heat, then whisk in sifted powdered sugar and vanilla extract until creamy. This frosting should be slightly thick yet pourable.

Once the cake comes out of the oven, immediately pour the warm frosting over the hot cake, spreading it quickly to cover the entire surface. This creates the signature glossy, fudgy layer that melds into the cake. Let it cool slightly before slicing into squares.

For an authentic touch, you can sprinkle chopped pecans over the frosting before it sets. This adds a nutty crunch that pairs perfectly with the rich chocolate flavor. The result is a moist, decadent cake with a gooey topping that makes it a true Texan classic.

Texas Sheet Cake is more than just a dessert—it’s a piece of culinary tradition. Ella Chef’s version keeps it simple yet indulgent, with a rich chocolate base and fudgy frosting that come together beautifully. Perfect for potlucks, family gatherings, or casual dinners, this cake serves a crowd with ease while delivering maximum flavor.
