Ingredients
For the Cake:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1 cup unsalted butter
- 1 cup water
- 1/4 cup unsweetened cocoa powder
- 1/2 cup sour cream
- 2 large eggs
- 1 teaspoon baking soda
- 1 teaspoon vanilla extract
- 1/2 teaspoon salt
For the Frosting:
- 1/2 cup unsalted butter
- 1/4 cup unsweetened cocoa powder
- 6 tablespoons milk
- 3 cups powdered sugar
- 1 teaspoon vanilla extract
- 1 cup chopped walnuts or pecans (optional)
Step-by-Step Instructions
Step 1: Preheat your oven to 350°F (175°C). Grease and flour a 10×15-inch jelly roll pan or a similar-sized baking sheet.
Step 2: In a large mixing bowl, whisk together the flour, sugar, baking soda, and salt until well combined.
Step 3: In a medium saucepan, combine the 1 cup of butter, water, and 1/4 cup cocoa powder. Heat over medium heat until the butter melts and the mixture comes to a gentle boil.
Step 4: Pour the hot chocolate mixture over the dry ingredients and stir until just combined.
Step 5: In a separate small bowl, whisk together the sour cream, eggs, and vanilla extract. Add this to the chocolate mixture and stir until smooth.
Step 6: Pour the batter into the prepared pan and spread evenly. Bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
Step 7: While the cake bakes, prepare the frosting. In a medium saucepan, combine the 1/2 cup butter, 1/4 cup cocoa powder, and milk. Heat until the butter melts and the mixture just begins to boil.
Step 8: Remove from heat and whisk in the powdered sugar and vanilla extract until smooth. Stir in nuts if using.
Step 9: As soon as the cake comes out of the oven, pour the warm frosting over the hot cake and spread evenly with a spatula.
Step 10: Allow the cake to cool completely before cutting into squares. This allows the frosting to set properly.
Expert Tips
For the Best Texture: Be careful not to overmix the batter once you add the wet ingredients. Overmixing can develop gluten and make the cake tough instead of tender.
Pan Choice Matters: Use a true jelly roll pan or rimmed baking sheet rather than a cake pan. The larger surface area helps create the signature thin layer that defines authentic Texas sheet cake.
Sour Cream Secret: The sour cream is what makes this cake exceptionally moist. For best results, use full-fat sour cream and bring it to room temperature before mixing.
Frosting Timing: The key to that signature fudgy frosting is pouring it over the cake while both are still warm. This creates a perfect seal that keeps the cake moist and allows the frosting to soak in slightly.
This classic Texas dessert pairs beautifully with a cold glass of milk or a scoop of vanilla ice cream. It’s also one of those easy desserts for crowds that always disappears quickly at gatherings.
