  • 1 teaspoon (4.2 ml) vanilla extract
  • 3 ½ cups (437.5 g) powdered sugar
  • 1 cup (109 g) chopped pecans (optional)


  • Preheat your oven to 350 degrees F.
  • Spray a half-sheet pan (13×18 inches) or (11 x 16 x 1.5-inch jelly roll) and line the bottom with parchment paper. Set aside.
  • Add butter, water and cocoa in a large saucepan place on medium high heat and bring to a boil.
  • Remove pan from stove and add the brown and granulated sugar followed by flour, baking soda, and salt. Mix until blended. 
  • Next add eggs, vanilla extract and sour cream. Mix with hand-held mixer until thoroughly mixed.
  • Pour cake batter into prepared pan. Bake in preheated oven for about 18- 20 minutes, or until a toothpick inserted into the center comes out clean.
  • Let it cool for about 20-30 minutes.

Chocolate Frosting

  • Add milk, cocoa and butter in a medium saucepan. Bring to a boil, then remove from heat.
  • Stir in the confectioners' sugar and vanilla, mixing until blended. Spread frosting over warm cake.
  • Sprinkle with roasted chopped pecans, or sprinkles, if desired


  • For a 13 x 18-inch sheet pan or an 11 x 16 x 1.5-inch jelly roll pan, bake it in a preheated oven for about 18-20 minutes or until a toothpick inserted in the center comes out clean.
  • For a 10 x 14-inch sheet pan. The same baking time also applies, 18-20 minutes until the toothpick inserted comes out clean.
  • Adjust bake time to the sheet pan’s size. If you opt for a thinner kind of Texas Sheet Cake. I prefer mine exactly how it looks above with just the right ratio of frosting to cake.
  • Oven temperature factor. The baking time though will still vary because everyone’s oven is different.
  • Please keep in mind that nutritional information is a rough estimate and can vary greatly based on the products used.
