How to make Texas sheet cake

Ingredients

For the cake:

• 1 cup butter
• 1 cup water
• 5 tbsp unsweetened cocoa powder
• 2 cups flour
• 2 cups sugar
• 1 tsp baking soda
• 1/2 tsp salt
• 1 tsp vanilla extract
• 1/2 cup buttermilk
• 2 large eggs

For the icing:

• 1/2 cup butter
• 6 tbsp milk
• 4 tbsp unsweetened cocoa powder
• 1 tsp vanilla extract
• 4 cups powdered sugar
• 1/2 cup finely chopped pecans

Substitutes

If you don’t have buttermilk, mix 1/2 cup milk with 1/2 tbsp lemon juice or white vinegar and let it sit for a few minutes. Omit pecans for a nut-free icing. For dairy-free options, use margarine and a plant milk. Swap in a 1:1 gluten-free flour blend if needed.

Equipment

You’ll need an 18×13 inch sheet pan, a small saucepan, a whisk, a mixing bowl, and an electric mixer (or a strong hand with a whisk).

Instructions

Preparation:

1. Preheat oven to 350°F (175°C). Lightly grease an 18×13 inch pan with nonstick spray.
2. In a small saucepan over medium heat, melt 1 cup butter. Stir in 1 cup water and 5 tbsp cocoa powder. Bring to a boil, then remove from heat and let cool slightly.
3. In a large bowl, whisk together 2 cups flour, 2 cups sugar, 1 tsp baking soda, and 1/2 tsp salt. Add 1 tsp vanilla, 1/2 cup buttermilk, and 2 eggs; beat until combined.
4. Stir the warm chocolate mixture into the batter and beat until smooth. Spread evenly into the prepared pan.
5. Bake 20–25 minutes, until the cake springs back when lightly touched.
6. While the cake bakes, make the icing: melt 1/2 cup butter in a saucepan over medium heat. Whisk in 6 tbsp milk, 4 tbsp cocoa powder, and 1 tsp vanilla. Remove from heat and stir in 4 cups powdered sugar until smooth. Fold in 1/2 cup chopped pecans.
7. Pour the warm icing over the hot cake so it seeps into the surface. Let the cake cool before slicing.

Tips

• Measure ingredients accurately for consistent texture.
• Pour the icing while the cake is still hot to achieve a slightly absorbed, fudgy topping.
• Avoid overbaking; check for doneness at 20 minutes.

Recipe variations

1. Nut-free: Leave out the pecans from the icing.
2. Spicy kick: Add a pinch of cayenne or cinnamon to the batter for warmth.
3. Extra fudge: Stir chocolate chips into the hot icing for a richer finish.
4. Gluten-free: Use a 1:1 gluten-free flour blend.

What to serve with

• Vanilla or butter pecan ice cream
• Lightly sweetened whipped cream
• A bright, tart beverage like lemonade to balance the richness

Frequently asked questions

Can I make this cake ahead? Yes — bake and cool the cake, then store covered at room temperature for up to 3 days or refrigerate for up to a week.

How do I store leftovers? Keep slices in an airtight container. For longer storage, wrap slices and freeze up to 3 months; thaw in the fridge overnight.

What if I don’t have an 18×13 pan? A 9×13 pan works; expect a thicker cake and add a few minutes to the bake time, checking for doneness.

How do I keep the cake moist? Use the proper amounts of butter and buttermilk, and avoid overbaking. Remove from the oven as soon as the surface springs back.
