Texas Sheet Cake (Big-Batch Recipe)

by

Introduction

Texas Sheet Cake is a rich, ultra-moist, chocolate cake baked in a large sheet pan and topped with warm, fudgy chocolate frosting that’s poured over the cake while it’s still hot. Unlike layered cakes, this dessert is thin, soft, and incredibly easy to serve to a crowd. It’s especially popular across the Southern United States and is a staple at potlucks, family reunions, and church gatherings.

This “big recipe” version is perfect for large parties and celebrations.

🏛 History of Texas Sheet Cake

The exact origins of Texas Sheet Cake are debated. Despite the name, there’s no official evidence that it originated in Texas, but it became widely popular there during the mid-20th century. Recipes began appearing in Southern cookbooks and newspapers in the 1950s and 1960s.

The name “Texas” likely refers to its large size — everything is bigger in Texas! The thin sheet-pan style and pour-over frosting made it practical for feeding large gatherings.

For the Cake:

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

🍫 For the Frosting:

  • 1 ½ cups unsalted butter (3 sticks)
  • ¾ cup unsweetened cocoa powder
  • 1 cup milk
  • 2 teaspoons vanilla extract
  • 6 cups powdered sugar
  • 1 ½ cups chopped pecans (optional)

👩‍🍳 Instructions & Methods

Step 1: Prepare the Pan

  • Preheat oven to 350°F (175°C).
  • Grease a large 18×13-inch sheet pan.

Step 2: Mix Dry Ingredients

  • In a large bowl, whisk together:
    • Flour
    • Sugar
    • Baking soda
    • Salt

Set aside.

Step 3: Prepare Chocolate Mixture

  • In a saucepan over medium heat:
    • Melt butter
    • Add water and cocoa powder
    • Bring just to a boil
  • Remove from heat.

Step 4: Combine

  • Pour hot chocolate mixture over dry ingredients.
  • Mix well.
  • Add sour cream, eggs, and vanilla.
  • Stir until smooth (do not overmix).

Step 5: Bake

  • Pour batter into prepared sheet pan.
  • Bake for 18–22 minutes (until toothpick comes out clean).

🍫 Frosting Method (Very Important!)

While cake is baking:

  1. Melt butter in saucepan.
  2. Add cocoa and milk. Bring to a gentle boil.
  3. Remove from heat.
  4. Stir in vanilla and powdered sugar.
  5. Add pecans if desired.

👉 Pour frosting over warm cake immediately after removing it from oven.
The heat helps the frosting spread evenly and slightly soak into the cake.

🧱 Formation & Texture

  • Thin, flat sheet cake
  • Moist and tender crumb
  • Slightly dense but soft
  • Smooth, glossy chocolate frosting on top
  • Light crackle on surface once set

The frosting sets into a soft fudge layer — not thick like buttercream.
