Step-by-Step Instructions
Preparing the Cake Batter
Preheat your oven to 350°F. Grease a 15×10-inch jelly roll pan or a 9×13-inch baking pan. In a large mixing bowl, whisk together flour, sugar, baking soda, and salt until well combined.
In a medium saucepan, combine butter, water, and cocoa powder. Bring to a boil over medium heat, stirring constantly. Remove from heat and pour the hot mixture over the dry ingredients. Stir until just combined.
In a separate small bowl, whisk together sour cream, eggs, and vanilla extract. Add this to the cake batter and mix until smooth and well incorporated. Pour the batter into your prepared pan and spread evenly.
Baking to Perfection
Bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean. The cake should spring back when lightly touched. While the cake is baking, prepare the frosting.
Making the Fudge Frosting
In a medium saucepan, combine butter, cocoa powder, and milk. Bring to a boil, then remove from heat. Whisk in powdered sugar and vanilla extract until smooth. If using nuts, stir them in at this point.
Frosting the Cake
Once the cake is out of the oven, immediately pour the warm frosting over the hot cake. Use a spatula to spread it evenly across the surface. Allow the cake to cool completely before cutting into squares.
Expert Tips for the Best Results
Choose the right pan: A jelly roll pan gives you the traditional thin Texas sheet cake texture, while a 9×13-inch pan creates a thicker, more cake-like dessert.
Don’t overmix: Mix the batter just until combined to ensure a tender crumb. Overmixing can lead to a tough cake.
Room temperature ingredients: For best results, use room temperature eggs and sour cream to help the ingredients incorporate more evenly.
Frost immediately: Pouring the warm frosting over the hot cake allows it to soak in slightly, creating that signature fudgy texture.
