Texas Sheet Cake: Complete Recipe, History and Chocolate Pecan Frosting Guide

Texas Sheet Cake is one of the most beloved desserts in the Lone Star State — a rich, thin chocolate cake baked in a large sheet pan and finished with a warm poured chocolate-pecan frosting that sets into a fudge-like layer as it cools. Consequently, this crowd-feeding dessert is a staple at Texas church potlucks, family reunions, office parties, and any gathering where feeding a large group is the priority. This guide covers the complete Texas Sheet Cake recipe, history, and tips for making it perfectly.

What Is Texas Sheet Cake?

Texas Sheet Cake is a thin chocolate cake baked in a large sheet pan — typically a 15×10 or 18×13 inch jelly roll pan — and topped with a warm poured frosting that combines cocoa, butter, milk, powdered sugar, and chopped pecans. Furthermore, the cake itself is made with buttermilk for a slight tang, cocoa powder for deep chocolate flavor, and a modest amount of flour that keeps the texture dense and fudgy rather than light and airy. As a result, Texas Sheet Cake delivers intense chocolate flavor in every bite from both the cake and the matching frosting.

Texas Sheet Cake Recipe

Here is the complete Texas Sheet Cake recipe for a 15×10 inch sheet pan serving approximately 24 people.

Cake Ingredients

• 2 cups all-purpose flour
• 2 cups granulated sugar
• 1 teaspoon baking soda
• 1/2 teaspoon salt
• 1 cup (2 sticks) unsalted butter
• 1 cup water
• 1/4 cup unsweetened cocoa powder
• 1/2 cup buttermilk
• 2 large eggs
• 1 teaspoon vanilla extract

Frosting Ingredients

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

Texas Sheet Cake Instructions

• Preheat oven to 350 degrees Fahrenheit. Grease and flour a 15×10 inch sheet pan or line with parchment.
• Mix dry ingredients: Whisk flour, sugar, baking soda, and salt in a large bowl.
• Make chocolate mixture: Melt butter in a saucepan with water and cocoa over medium heat, stirring until smooth. Bring just to a boil then remove from heat.
• Combine: Pour the hot chocolate mixture over the dry ingredients and stir to combine. Add buttermilk, eggs, and vanilla and mix until smooth.
• Bake: Pour batter into prepared pan and spread evenly. Bake 20 to 25 minutes until a toothpick comes out clean.
• Make frosting while cake bakes: Melt butter in a saucepan with milk and cocoa over medium heat. Bring to a boil then remove from heat. Stir in powdered sugar and vanilla until smooth. Fold in pecans.
• Frost immediately: Pour warm frosting over the hot cake directly out of the oven. Spread evenly. The frosting sets as it cools — do not refrigerate to speed setting.

Tips for the Best Texas Sheet Cake

The most important tip for Texas Sheet Cake is to pour the frosting on the cake while both are still hot — this creates the characteristic fudge-like frosting texture that distinguishes Texas Sheet Cake from a frosted cake where the frosting is applied after cooling. Furthermore, do not overbake the cake — a toothpick should come out with moist crumbs rather than completely clean, as the dense texture improves with slight underbaking. As a result of these two techniques, your Texas Sheet Cake will have the authentic texture that makes it one of the most requested desserts at any Texas gathering.
