Equipment You’ll Need

• 18×13-inch rimmed baking sheet (jelly roll pan)
• Medium saucepan
• Large mixing bowl
• Whisk
• Spatula
• Measuring cups and spoons

Ingredients

• For the Cake:
• 2 cups all-purpose flour
• 2 cups granulated sugar
• 1/2 teaspoon salt
• 1 cup unsalted butter (2 sticks)
• 4 tablespoons unsweetened cocoa powder
• 1 cup water
• 1/2 cup buttermilk, at room temperature
• 2 large eggs, lightly beaten, at room temperature
• 1 teaspoon baking soda
• 1 teaspoon vanilla extract
• For the Fudgy Pecan Frosting:
• 1/2 cup unsalted butter (1 stick)
• 4 tablespoons unsweetened cocoa powder
• 6 tablespoons whole milk or buttermilk
• 1 (16 ounce) box powdered sugar (about 4 cups), sifted
• 1 teaspoon vanilla extract
• 1 cup pecans, toasted and chopped

Instructions

1. Preheat your oven to 375°F (190°C). Grease and flour an 18×13-inch rimmed baking sheet, or spray thoroughly with non-stick baking spray. Set aside.
2. In a large mixing bowl, whisk together the flour, granulated sugar, and salt. Set this aside as well.
3. In a medium saucepan over medium heat, combine the 1 cup of butter, 4 tablespoons of cocoa powder, and 1 cup of water. Bring the mixture to a rolling boil, whisking occasionally until the butter is completely melted and everything is smooth.
4. Carefully pour the hot butter mixture into the large bowl with the flour mixture. Whisk until just combined. Be careful not to overmix.
5. In a separate small bowl, whisk together the buttermilk, beaten eggs, baking soda, and vanilla extract until smooth.
6. Pour the buttermilk mixture into the chocolate batter and whisk gently until everything is fully incorporated and the batter is smooth. You’ll have a thin, liquidy batter.
7. Pour the batter into the prepared baking sheet and spread it into an even layer with a spatula.
8. Bake for 18-20 minutes, or until a wooden skewer or toothpick inserted into the center comes out clean or with a few moist crumbs attached. The cake is thin, so it bakes quickly!
9. About 5 minutes before the cake is finished baking, start making the frosting. In the same saucepan (no need to wash it!), combine the 1/2 cup of butter, 4 tablespoons of cocoa powder, and 6 tablespoons of milk.
10. Bring the frosting mixture to a boil over medium heat, whisking constantly. Once it boils, remove it from the heat immediately.
11. Whisk in the sifted powdered sugar and vanilla extract until the frosting is glossy and smooth. If it seems too thick, you can add another tablespoon of milk.
12. Stir in the chopped toasted pecans.
13. As soon as the cake comes out of the oven, pour the warm frosting all over the hot cake. Use an offset spatula to gently spread it to the edges.
14. Let the cake cool completely in the pan before cutting into squares and serving. The frosting will set into a perfect fudgy layer as it cools.

Expert Cooking Tips

• Don’t have buttermilk? Make your own! Add 1/2 tablespoon of white vinegar or lemon juice to a measuring cup, then fill with milk to the 1/2 cup line. Let it sit for 5 minutes before using.
• Toasting the pecans is an optional step, but it dramatically enhances their flavor and adds a delightful crunch. Spread them on a baking sheet and toast at 350°F for 5-7 minutes until fragrant.
• The key to the classic Texas Sheet Cake texture is pouring the warm frosting over the warm cake. This allows the frosting to slightly melt into the top layer of the cake, creating an incredibly moist and fudgy result.
• Sift your powdered sugar for the frosting! This is crucial for avoiding lumps and achieving a perfectly smooth, glossy finish.

Substitutions and Variations

For a nut-free version, simply omit the pecans from the frosting; the cake is still incredibly delicious without them. If you prefer other nuts, walnuts also work wonderfully. While this recipe is best with all-purpose flour, you can try a 1-to-1 gluten-free baking flour blend, but be aware that the texture may be slightly different. For the buttermilk, you can use the DIY substitute mentioned in the tips or even plain yogurt or sour cream thinned with a little milk.

Common Mistakes to Avoid

The most common mistake is overbaking the cake. Because it’s so thin, it bakes very quickly. Overbaking will result in a dry, crumbly cake. Start checking it at the 18-minute mark. Another error is letting either the cake or the frosting cool down too much before combining them. The magic happens when the warm, pourable frosting meets the hot cake, so time your frosting preparation to finish just as the cake comes out of the oven.

Serving Suggestions

This cake is a star all on its own, but it’s absolutely divine served slightly warm with a scoop of creamy vanilla bean ice cream. The contrast of the warm, fudgy cake and the cold, creamy ice cream is pure bliss. It’s also perfect with a dollop of fresh whipped cream or simply paired with a tall, cold glass of milk for a classic treat. Because it’s made in a large pan, it’s easy to cut into squares, making it the perfect dessert for potlucks, BBQs, and parties.

Storage and Reheating Tips

Store the cake, covered tightly with plastic wrap or a lid, at room temperature for up to 3 days. If you need to store it longer, it will keep well in the refrigerator for up to a week. The cake can also be frozen! Cut it into individual squares and wrap them tightly in plastic wrap, then place in a freezer-safe bag or container. It will last for up to 3 months. Thaw at room temperature before enjoying.

Frequently Asked Questions

What makes a Texas Sheet Cake different from a regular chocolate cake?

A Texas Sheet Cake is characterized by its large size (baked in a jelly roll pan), its thin and incredibly moist, almost brownie-like texture, and its signature cooked fudgy frosting that’s poured over the cake while it’s still hot.

Can I make this cake in a 9×13-inch pan?

Yes, you can, but you’ll need to adjust the baking time significantly. A cake in a 9×13-inch pan will be much thicker and will likely need 30-35 minutes to bake. Keep a close eye on it and use a toothpick to test for doneness.

Why is the batter so thin?

Don’t be alarmed by the thin, liquidy batter! This is completely normal for a Texas Sheet Cake. The high liquid content is what contributes to the cake’s famously moist and tender crumb.

Do I have to use an electric mixer?

Nope! That’s one of the best parts of this recipe. The cake batter and frosting are both made in a saucepan and mixed by hand with a whisk, making it a wonderfully low-fuss dessert with minimal cleanup.
