Texas Sheet Cake Recipe: Step-by-Step Guide with Chocolate Pecan Frosting

Texas Sheet Cake is the ultimate crowd-feeding chocolate dessert — a rich, thin cake baked in a large sheet pan and finished with a warm chocolate-pecan frosting that sets into a fudge-like layer as it cools. Consequently, this Texas dessert staple appears at church potlucks, family reunions, office parties, and holiday gatherings across the state because it feeds a crowd, transports easily, and delivers consistent chocolate satisfaction every time. This complete recipe guide walks you through every step.

Texas Sheet Cake Ingredients

For the Cake (serves 24)

• 2 cups all-purpose flour
• 2 cups granulated sugar
• 1/2 teaspoon salt
• 1 teaspoon baking soda
• 1/2 cup (1 stick) unsalted butter
• 1/2 cup vegetable oil (or substitute a second stick of butter)
• 1 cup water
• 1/4 cup unsweetened cocoa powder
• 1/2 cup buttermilk
• 2 large eggs, beaten
• 1 teaspoon vanilla extract

For the Chocolate Pecan Frosting

• 1/2 cup (1 stick) unsalted butter
• 6 tablespoons whole milk
• 1/4 cup unsweetened cocoa powder
• 4 cups (1 pound) powdered sugar, sifted
• 1 teaspoon vanilla extract
• 1 cup pecans, chopped (optional but traditional)

Step-by-Step Instructions

Step 1 — Prepare the pan: Preheat oven to 350 degrees Fahrenheit. Grease a 15×10 inch jelly roll pan or an 18×13 inch half sheet pan with butter or cooking spray and dust lightly with flour. Alternatively, line with parchment paper.

Step 2 — Mix dry ingredients: In a large mixing bowl, whisk together flour, sugar, salt, and baking soda. Set aside.

Step 3 — Make the chocolate mixture: In a medium saucepan over medium heat, combine butter, oil, water, and cocoa powder. Stir constantly until the butter melts and the mixture just comes to a boil. Remove immediately from heat.

Step 4 — Combine wet and dry: Pour the hot chocolate mixture over the dry ingredients and stir until mostly combined. Add buttermilk, beaten eggs, and vanilla and mix until smooth. The batter will be thin — this is correct.

Step 5 — Bake: Pour batter into prepared pan and spread evenly to the corners. Bake at 350 degrees for 18 to 22 minutes until a toothpick inserted in the center comes out with just a few moist crumbs. Do not overbake.

Step 6 — Make frosting while cake bakes: About 5 minutes before the cake comes out of the oven, combine butter, milk, and cocoa in a saucepan over medium heat. Stir until butter melts and mixture comes to a boil. Remove from heat and whisk in sifted powdered sugar and vanilla until smooth. Fold in chopped pecans.

Step 7 — Frost immediately: Remove cake from oven and immediately pour the warm frosting over the hot cake. Spread quickly and evenly with an offset spatula — the frosting will begin setting as it hits the hot cake surface. Do not refrigerate to speed up setting.

Key Tips for the Best Texas Sheet Cake

• Hot frosting on hot cake is the non-negotiable rule — this creates the fudge-like texture
• Sift the powdered sugar to prevent lumps in the frosting
• Don’t overbake — slightly underdone cake becomes fudgier as it cools under the frosting
• Work quickly with the frosting — it sets fast, so pour and spread immediately
• Buttermilk is important — it adds tang and keeps the cake tender; don’t substitute regular milk
