Ingredients
For the Cake:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup butter, softened
- 1/4 cup cocoa powder
- 1 cup water
- 1/2 cup sour cream
- 2 large eggs
- 1 teaspoon vanilla extract
For the Frosting:
- 1/2 cup butter
- 1/4 cup cocoa powder
- 6 tablespoons milk or cream
- 3 1/2 cups powdered sugar
- 1 teaspoon vanilla extract
- 1 cup chopped pecans or walnuts (optional)
Step-by-Step Instructions
Step 1: Preheat your oven to 350°F (175°C). Grease and flour a 15×10-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, melt the butter over medium heat. Add the cocoa powder and water, stirring constantly until smooth. Bring the mixture just to a boil, then remove from heat.
Step 4: Pour the hot chocolate mixture over the dry ingredients and mix until well combined. The batter will be thick at this stage.
Step 5: Add the sour cream, eggs, and vanilla extract to the batter. Mix until smooth and well incorporated.
Step 6: Pour the batter into your 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 butter, cocoa powder, and milk. Heat over medium, stirring constantly, until the butter melts and the mixture is smooth.
Step 8: Remove from heat and whisk in the powdered sugar and vanilla until smooth. Stir in chopped nuts if using.
Step 9: As soon as the cake comes out of the oven, pour the warm frosting over the hot cake. Spread evenly with a spatula.
Step 10: Allow the cake to cool completely before slicing and serving. This allows the frosting to set perfectly.
Expert Tips for the Perfect Sheet Cake
Room Temperature Ingredients: For the best texture, make sure your eggs and sour cream are at room temperature before mixing. This helps create a smoother batter and more even baking.
Don’t Overbake: Sheet cakes bake quickly, so watch carefully toward the end. The cake is done when it springs back lightly when touched and a toothpick comes out with a few moist crumbs.
Frosting Timing: The key to that signature Texas sheet cake texture is pouring the warm frosting over the hot cake. This creates a delicious fudgy layer that soaks slightly into the cake.
Storage: This cake stays moist for days when stored in an airtight container at room temperature. For longer storage, it freezes beautifully without the frosting. If you love easy chocolate desserts, you’ll appreciate how well this cake holds up.
Customization: Feel free to add different mix-ins like chocolate chips or swap the nuts for your favorites. The base recipe is versatile enough to accommodate personal touches while maintaining its classic charm.
Frequently Asked Questions
Can I make this cake ahead of time?
Absolutely! This cake actually tastes better the next day as the flavors have more time to develop. Just store it covered at room temperature.
What pan size works best?
A 15×10-inch jelly roll pan is ideal. If you use a different size, adjust baking time accordingly. A 9×13 pan will work but will yield a thicker cake that needs longer baking.
Can I use Greek yogurt instead of sour cream?
Yes, Greek yogurt works as a great substitute for sour cream and provides similar moisture and tanginess to the cake.
How many servings does this make?
This generous sheet cake serves 20-24 people, making it perfect for large gatherings and parties where you need to feed a crowd with minimal effort.
Why is it called Texas sheet cake?
The name comes from the large size typical of Texas-style hospitality, where everything is bigger and made to share with friends and family.
