Expert Tips for the Best Texas Sheet Cake
1. Jelly Roll Pan Selection
A standard jelly roll pan is typically 12×17 inches with a depth of 1 inch. If your pan is slightly smaller, like 11×16 inches, that works too. Just be sure to adjust the cooking time if necessary by checking the cake a few minutes earlier.
2. Greasing the Pan
For easy removal, spray the pan with nonstick baking spray or grease it well and dust it lightly with flour. This prevents sticking and ensures the cake can be easily sliced and served.
3. Quality Cocoa Powder
Use a high-quality unsweetened cocoa powder for this recipe. A premium brand like Ghirardelli adds a rich chocolate flavor that makes a noticeable difference in the final product.
4. Cooling the Chocolate Mixture
After combining the butter, water, and cocoa, allow the mixture to cool for at least 20 minutes before adding it to the dry ingredients. If the mixture is too hot, it could cook the eggs, which could affect the cake’s texture.
5. Work Quickly with Frosting
The frosting sets up fast, so be ready to pour and spread it immediately over the warm cake. It helps to have your ingredients measured and prepared in advance.
6. Spread Carefully
When spreading the frosting, work quickly but carefully. A spatula will help create an even layer of frosting without pulling up the soft cake beneath.
