Texas sheet cake is a classic Southern dessert known for its rich chocolate flavor and irresistibly moist texture. This cake is baked in a large sheet pan, making it perfect for gatherings or potlucks. The chocolatey glaze frosting seeps into the cake while still warm, creating a luscious finish that’s both simple and satisfying.
Ingredients
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1/2 teaspoon salt
- 1 teaspoon baking soda
- 1 cup unsalted butter (2 sticks)
- 1 cup water
- 4 tablespoons unsweetened cocoa powder
- 1/2 cup buttermilk, room temperature
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup chopped pecans or walnuts (optional)
- For the frosting:
- 1/2 cup unsalted butter (1 stick)
- 1/4 cup unsweetened cocoa powder
- 6 tablespoons milk
- 3 1/2 cups powdered sugar, sifted
- 1 teaspoon vanilla extract
- 1 cup chopped pecans or walnuts (optional)
Instructions
- Preheat your oven to 350°F (175°C). Lightly grease a 15×10-inch jelly roll pan or line it with parchment paper for easier cleanup.
- In a medium bowl, whisk together the flour, sugar, salt, and baking soda until evenly combined. Set aside.
- In a medium saucepan over medium heat, combine the butter, water, and cocoa powder. Stir occasionally until the butter melts and the mixture begins to boil. Remove from heat immediately once it reaches a boil.
- Pour the hot cocoa mixture into the dry ingredients. Stir gently until just combined; the batter will be thick.
- In a small bowl, whisk the buttermilk, eggs, and vanilla extract together. Add this to the batter and mix until smooth and fully incorporated.
- If using, fold in the chopped nuts for some added texture and flavor.
- Pour the batter into the prepared pan, spreading it evenly with a spatula.
- Bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs attached.
- While the cake bakes, prepare the frosting: In a small saucepan, melt the butter over medium heat. Stir in the cocoa powder and milk, and bring to a gentle boil. Remove from heat and whisk in the powdered sugar and vanilla extract until smooth.
- Once the cake is out of the oven, immediately pour the warm frosting evenly over the top. Spread it gently with a spatula if needed. Sprinkle additional chopped nuts on top if desired.
- Allow the cake to cool completely in the pan on a wire rack before slicing into squares and serving.
Tips
- Buttermilk substitute: If you don’t have buttermilk, mix 1/2 cup milk with 1/2 tablespoon white vinegar or lemon juice. Let it sit for 5 minutes before using to mimic buttermilk’s acidity and moisture.
- Don’t overmix: When combining wet and dry ingredients, mix just until combined to avoid a tough cake texture.
- Use fresh cocoa powder: For the richest chocolate flavor, use high-quality unsweetened cocoa powder. Dutch-processed cocoa can be used but may slightly alter the taste and color.
- Storage: Store leftover cake in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days. Bring to room temperature before serving for best flavor.
Serving Suggestions
Texas sheet cake is delicious served on its own thanks to its rich chocolate glaze, but you can elevate it with a scoop of vanilla ice cream or a dollop of freshly whipped cream. For a festive touch, sprinkle some extra chopped nuts or chocolate shavings on top. This cake also pairs well with fresh berries like raspberries or strawberries, which add a bright contrast to the deep chocolate flavor.
Variations
You can customize Texas sheet cake in many ways to suit your taste or occasion. For a nut-free version, simply omit the pecans or walnuts. To add a hint of spice, try incorporating 1/2 teaspoon of cinnamon or a pinch of cayenne pepper into the batter. For a more decadent dessert, swirl in some cream cheese frosting after the chocolate glaze sets. Another popular variation is to add a layer of caramel or butterscotch chips to the batter before baking for extra gooeyness.
Storage and Reheating
Store Texas sheet cake at room temperature in an airtight container for up to 3 days. If your kitchen is warm or humid, refrigeration is recommended, where it will keep for up to 5 days. To prevent the frosting from drying out, cover the cake loosely with plastic wrap or a cake dome.
To reheat, warm individual slices in the microwave for 10-15 seconds to soften the frosting and cake, enhancing the moist texture. Avoid overheating as this can dry out the cake.
If you want to freeze the cake, wrap it tightly in plastic wrap and then aluminum foil to prevent freezer burn. Freeze for up to 2 months. Thaw overnight in the refrigerator before serving.
Frequently Asked Questions
Can I make Texas sheet cake ahead of time?
Yes, this cake can be made a day ahead and stored covered at room temperature or refrigerated. The flavors often improve after resting, but be sure to bring it to room temperature before serving for the best texture.
Is it necessary to use buttermilk?
Buttermilk adds acidity that helps tenderize the cake and react with baking soda for leavening. If you don’t have buttermilk, you can substitute with milk plus vinegar or lemon juice, or use plain yogurt thinned with a little milk.
Why is my Texas sheet cake dry?
Dry cake usually results from overbaking or overmixing the batter. Make sure to check the cake at 25 minutes and remove it as soon as a toothpick comes out mostly clean. Also, mix ingredients just until combined to avoid developing too much gluten.
Can I use a different pan size?
The traditional Texas sheet cake is baked in a 15×10-inch pan, which gives it the right thinness and baking time. Using a smaller pan will make the cake thicker and require longer baking, while a larger pan will make it thinner and bake faster. Adjust baking time accordingly and monitor closely.
How do I get the frosting smooth and glossy?
Make sure the frosting ingredients are well combined and hot when poured over the cake. Pour it immediately after the cake comes out of the oven so it seeps in slightly. Use a spatula to spread it evenly but gently to maintain a smooth finish.
Can I make this cake gluten-free?
Yes, you can substitute the all-purpose flour with a 1:1 gluten-free baking flour blend that contains xanthan gum. The texture may be slightly different but still moist and delicious.
Texas sheet cake is a beloved staple for a reason: its ease, moistness, and rich chocolate flavor make it a crowd-pleaser every time. With these tips and variations, you can confidently bake a perfect sheet cake to enjoy with family and friends.
