This recipe is straightforward, uses simple ingredients, and yields a generous, shareable cake that everyone will love.

Ingredients

2 cups (240g) all-purpose flour
2 cups (400g) granulated sugar
1/2 teaspoon salt
1 teaspoon baking soda
1/2 cup (115g) unsalted butter
1 cup (240ml) water
1/3 cup (80ml) vegetable oil
3 tablespoons unsweetened cocoa powder
1 teaspoon vanilla extract
1 cup (240ml) buttermilk or milk
1 large egg

Instructions

Preheat your oven to 350°F (175°C). Grease a 10×15-inch sheet pan thoroughly with butter or non-stick spray and set aside.
Combine dry ingredients: In a large mixing bowl, whisk together the flour, sugar, salt, and baking soda. Set aside.

Make the chocolate mixture: In a medium saucepan over medium heat, melt the butter with water, vegetable oil, and cocoa powder. Bring to a gentle boil, stirring constantly. Once boiling, remove from heat.
Mix wet ingredients: Pour the hot chocolate mixture into the dry ingredients. Add vanilla extract, buttermilk (or milk), and the egg. Stir until just combined and smooth.
Pour batter into pan: Spread the batter evenly in the prepared sheet pan using a spatula. Make sure it reaches all edges for uniform baking.

Bake: Place in the preheated oven and bake for 20-25 minutes. The cake is done when a toothpick inserted into the center comes out clean or with just a few moist crumbs.
Cool: Remove from oven and let the cake cool in the pan for about 15 minutes. Then, transfer to a wire rack or leave it in the pan if serving soon.
Optional frosting: Once cooled, frost with chocolate frosting or a dusting of powdered sugar for added sweetness. Serve and enjoy.

Tips

Substitutions: You can substitute buttermilk with regular milk mixed with 1 teaspoon of vinegar or lemon juice if needed. For a dairy-free version, use almond or soy milk and dairy-free margarine.
Storage: Keep the cake covered at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days or freeze slices for up to 3 months.
Prevent dry cake: Do not overbake. Start checking for doneness at 20 minutes to ensure the cake remains moist.

Frosting options: Classic chocolate frosting, cream cheese frosting, or even a simple glaze work well. Add sprinkles or chopped nuts for extra texture.

Serving Suggestions

Serve this Texas sheet cake plain, topped with a dusting of powdered sugar, or with a scoop of vanilla ice cream for a decadent dessert. It pairs beautifully with a glass of milk or a cup of coffee, making it a versatile choice for any occasion.

Variations

Try adding chopped nuts, chocolate chips, or swirls of peanut butter to the batter before baking for extra flavor. You can also layer the cake with a cream cheese filling or a caramel drizzle for a more indulgent treat.

Storage and Reheating

Store the cake covered at room temperature for up to 2 days or refrigerate for up to 5 days. To reheat, warm individual slices in the microwave for 10-15 seconds to restore moisture and warmth. For best results, consume within the first 3-4 days for optimal freshness.

Frequently Asked Questions

Can I make this cake gluten-free?

Yes, substitute the all-purpose flour with a gluten-free flour blend suitable for baking. Keep in mind that texture and baking time may vary slightly, so monitor closely during baking.

Definitely. You can bake and cool the cake a day in advance. Store it covered at room temperature or refrigerated, and add frosting just before serving for the freshest taste.

What frosting pairs best with Texas sheet cake?

Traditional chocolate frosting is classic, but cream cheese frosting or a simple chocolate glaze also complement the moist, chocolatey cake beautifully. Add nuts or sprinkles for extra flair.

How do I prevent the cake from being dry?

Be careful not to overbake. Check for doneness around 20 minutes, and remove from the oven as soon as a toothpick inserted in the center comes out with moist crumbs. Also, avoid baking at too high a temperature.
