  1. Preheat an oven to 350 degrees F (175 degrees C). Grease an 11x17 jelly roll pan.
  2. Mix white sugar and flour in a large bowl. Combine 1 cup butter, water, and 3 tablespoons cocoa powder in a small saucepan; stir over medium heat until butter is melted and mixture is well combined. Pour melted butter mixture over sugar and flour; beat well. Beat in baking soda, buttermilk, eggs, and vanilla extract. Pour batter into prepared pan.
  3. Bake in preheated oven until a toothpick inserted into the center of cake comes out clean, 20 to 25 minutes. Remove from oven and allow to cool on a wire rack.
  4. Combine remaining 1/2 cup butter, 3 tablespoons cocoa powder, and milk in a small saucepan; stir over medium heat until butter is melted and mixture is well combined. Beat powdered sugar into the butter mixture, mixing until frosting is smooth. Stir pecans into frosting and pour over cooled cake.

When I ask my now grown kids what cake they want for their birthday, it's always been Texas Sheet Cake. I've been making this recipe for many many years. It always comes out great.

Just a warning: this batter is VERY runny. If it turns out like soup, don't be alarmed. I used cake flour (if you do this, be sure to add an extra 2 T. for every cup of flour), I also warmed the...

Chocolate sheet cake always goes over well at our family functions. While this wasn't the best sheet cake I've had or made it was good. I used a 10x15 sheet pan and it fit perfectly. Once you p...

This is liteally better than anything else in existence. Ever. I usually up the cocoa amounts and add mini chocolate chips to the batter and glaze, just because I'm a little over-obsessed with ...
