Dense, glossy, and studded with toasted pecans, this Texas sheet cake delivers big chocolate flavor with minimal fuss. It comes together fast, bakes in about 20 minutes, and gets its signature glossy frosting poured on while the cake is still hot.
Why this Texas sheet cake stands out for chocolate lovers
Unlike layer cakes, sheet cakes are baked in a shallow pan for tender crumb and fast baking. This recipe uses a hot cocoa-butter mixture to deepen the chocolate taste.
- Quick prep: You can mix the batter while the oven heats.
- Effortless frosting: A stove-top chocolate glaze is spread over the warm cake for a glossy finish.
- Toasted pecans add crunch and balance the sweetness.
Ingredients for the cake and pecan frosting
For the cake
- 1/2 cup (113 g) butter
- 1/2 cup water
- 2 tablespoons cocoa powder
- 1 cup granulated sugar
- 1 cup all-purpose flour
- Pinch of salt
- 1/2 teaspoon baking soda
- 1/4 cup buttermilk
- 1 large egg
- 1 teaspoon vanilla extract
For the frosting
- 1/4 cup (57 g) butter
- 2 tablespoons cocoa powder
- 3 tablespoons milk
- 2 cups powdered (confectioners’) sugar
- 1/2 teaspoon vanilla extract
- 1/2 cup toasted pecans, chopped (walnuts optional)
Step-by-step baking instructions
- Preheat the oven to 350°F (175°C).
- In a small saucepan, combine 1/2 cup butter, 1/2 cup water and 2 tablespoons cocoa over medium heat. Heat until the butter melts and the cocoa dissolves.
- In a mixing bowl, whisk together 1 cup sugar, 1 cup flour, a pinch of salt and 1/2 teaspoon baking soda.
- In a separate bowl, beat 1/4 cup buttermilk with 1 egg and 1 teaspoon vanilla.
- Pour the wet buttermilk mixture into the dry ingredients and stir until mostly combined.
- Add the warm cocoa-butter liquid to the batter and mix until smooth and uniform.
- Transfer batter to a greased 9×9-inch baking pan and spread evenly.
- Bake for about 20 minutes, or until a toothpick inserted near the center comes out clean.
- While the cake bakes, prepare the frosting so you can apply it right away.
How to make the glossy pecan frosting
- In a small saucepan, warm 1/4 cup butter, 2 tablespoons cocoa and 3 tablespoons milk until the mixture just begins to simmer.
- Remove the pan from the heat and whisk in 2 cups powdered sugar and 1/2 teaspoon vanilla until smooth.
- Fold in 1/2 cup toasted, chopped pecans.
- Spread the frosting over the hot cake. Do this while the cake is still hot so the glaze sets with a shiny, slightly crinkled surface.

Practical tips, variations and storage advice
- Toast pecans in a dry skillet for 3–5 minutes until fragrant. Let cool before chopping.
- Swap walnuts for pecans if you prefer a milder nut flavor.
- For a richer cake, use whole milk instead of buttermilk and add a tablespoon of sour cream.
- Serve warm or at room temperature. The frosting firms as it cools.
- Store leftovers covered at room temperature for 1–2 days, or refrigerate up to 5 days.
- Freeze individual slices wrapped tightly for up to one month. Thaw in the fridge overnight.
