Ingredients

Gather these simple ingredients to create your unforgettable Texas Sheet Cake:

For the Cake:

• 1 cup water (240 ml)
• 1 cup butter (227 g)
• 3 Tablespoons unsweetened cocoa powder (22.5 g)
• 2 cups all-purpose flour (240 g)
• 2 cups granulated sugar (400 g)
• 1 teaspoon baking soda (5 g)
• 1/2 teaspoon salt (2.5 g)
• 1/2 cup sour cream (120 g)
• 2 large eggs
• 1 teaspoon vanilla extract (5 ml)

For the Frosting:

• 6 Tablespoons milk (90 ml)
• 1/2 cup butter (115 g)
• 3 3/4 cups powdered sugar (450 g)
• 3 Tablespoons unsweetened cocoa powder (22.5 g)

Notes & Substitutions

For the cocoa powder, natural unsweetened cocoa works best here. You can substitute sour cream with plain full-fat yogurt or buttermilk for a similar tender crumb. If you need a dairy-free option for the cake, use vegetable oil instead of butter, but keep butter for the frosting for flavor. A 1:1 gluten-free all-purpose flour blend can also work in the cake for those with dietary needs.

Equipment

You only need a few basic tools to make this delightful chocolate sheet cake:

• 18×13 inch jelly roll pan (also called a half-sheet pan)
• Medium saucepan
• Large mixing bowls
• Whisk or spatula
• Electric hand mixer (optional, but helpful for extra smooth frosting)
• Measuring cups and spoons

Instructions

Creating this delightful Texas Sheet Cake is straightforward. Follow these steps for a perfectly moist and flavorful dessert.

1. Prep Oven & Pan: Preheat your oven to 350°F (175°C). Generously grease an 18×13 inch jelly roll pan. This ensures the cake releases easily.
2. Boil Wet Cake Mix: In a medium saucepan, combine the water, 1 cup butter, and 3 tablespoons unsweetened cocoa powder. Place over medium heat and bring the mixture to a rolling boil. Remove from heat immediately once boiling.
3. Mix Dry Cake Ingredients: In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking soda, and salt until well combined.
4. Mix Wet Cake Ingredients: In a separate small bowl, whisk together the sour cream, large eggs, and vanilla extract.
5. Combine Cake Batters: Pour the sour cream and egg mixture into the dry flour mixture. Stir gently with a whisk or spatula until just combined. Avoid overmixing to keep the cake tender.
6. Add Hot Chocolate Mix: Carefully pour the hot chocolate mixture from the saucepan into the cake batter. Mix well until everything is fully incorporated and no lumps remain. The hot liquid helps activate the cocoa and baking soda, creating a rich flavor.
7. Pour & Bake Cake: Pour the runny batter into your prepared 18×13 inch pan. Use a spatula to spread it evenly into a thin layer. Bake in the preheated oven for 15-20 minutes, or until a toothpick inserted into the center comes out clean. My oven usually finishes this cake in about 15 minutes.
8. Prepare Frosting (Mid-Bake): When the cake is about halfway through its baking time, start the frosting. In a medium saucepan, combine the 6 tablespoons milk, 1/2 cup butter, and 3 tablespoons unsweetened cocoa powder. Bring this mixture to a boil over medium heat, stirring occasionally.
9. Finish Frosting: Remove the boiling frosting mixture from the heat. Add the powdered sugar into the saucepan. Beat with a whisk or an electric hand mixer until the frosting is smooth and lump-free. Work quickly while it is warm.
10. Frost Hot Cake: Immediately pour the warm frosting over the warm, freshly baked cake. Use a spatula or the back of a spoon to spread it evenly across the entire surface. The warm cake absorbs some of the frosting, creating a truly decadent experience.
11. Set & Serve: Let the frosting set for about 10 minutes before slicing and serving. This allows the frosting to firm up slightly. Enjoy your delicious Texas Sheet Cake!

Pro Tips & Troubleshooting

• Prevent Lumpy Frosting: For the smoothest frosting, sift your powdered sugar and cocoa powder before adding them to the warm liquid. This eliminates any stubborn lumps.
• Achieve Perfect Texture: Never overmix the cake batter once you combine wet and dry ingredients. Overmixing develops gluten, leading to a tougher cake. Mix just until no streaks of flour remain.
• Ensure Cake Rise: Always use fresh baking soda. Old baking soda loses its leavening power, resulting in a flat cake.
• Avoid Frosting Separation: Ensure both the cake and frosting are warm when you combine them. The warm cake helps the frosting melt slightly and meld perfectly.
• Check for Doneness: A thin sheet cake cooks quickly. Check for doneness around the 15-minute mark. The center should spring back slightly when lightly touched.
• Don’t Overbake: Overbaking will dry out this moist chocolate sheet cake. Keep a close eye on it, as oven temperatures can vary.

Serving, Storage & Variations

Serve this delightful Texas Sheet Cake warm for the most fudgy, melt-in-your-mouth experience. It pairs wonderfully with a scoop of vanilla ice cream, a dollop of whipped cream, or a sprinkle of toasted pecans or walnuts.

Storage: Store any leftover cake covered tightly at room temperature for 1-2 days. For extended freshness, refrigerate the cake, covered, for up to 3-4 days.

Freezing: This cake freezes beautifully! Once completely cooled and the frosting has set, cut the cake into individual squares. Wrap each piece tightly in plastic wrap, then place them in an airtight freezer-safe container or bag. Freeze for up to 2-3 months. Thaw individual slices at room temperature or warm slightly in the microwave.

Different Pan Sizes: If you use a smaller 9×13 inch baking pan, increase the baking time to approximately 25-30 minutes, as the cake will be thicker. Always check for doneness with a toothpick.

Flavor Variations: Enhance the chocolate flavor by adding 1 teaspoon of instant espresso powder or a pinch of cinnamon to the cake batter.

Topping Ideas: Before the frosting sets, sprinkle with festive sprinkles, shredded coconut, or extra mini chocolate chips for added texture and appeal.
