Ingredients You’ll Need
- 2 sticks salted butter: Adds richness and moisture. If you’re in a pinch, unsalted butter works fine; just add a pinch of salt.
- 1 cup water: Helps create a tender, moist cake.
- 7 tablespoons unsweetened cocoa powder (I used Hershey’s dark): This adds intense chocolate flavor. Feel free to swap with Dutch-processed cocoa for a different depth of flavor.
- 2 cups all-purpose flour: The foundation of the cake; helps to hold it all together.
- 2 cups granulated sugar: Sweetens the cake perfectly. You might substitute with coconut sugar if preferred, though the texture may vary slightly.
- 1 teaspoon baking soda: This leavening agent helps the cake rise and stay fluffy.
- 3/4 teaspoon kosher salt: Enhances the chocolate flavor. Table salt can be used, but reduce the amount slightly.
- 2/3 cup buttermilk: Gives the cake a tender crumb and adds a subtle tang. Sour cream or plain yogurt can be used as a substitute if buttermilk isn’t available.
- 2 large eggs: Binds the ingredients and improves texture. They should be at room temperature for best incorporation.
- 1 teaspoon pure vanilla extract: Adds depth to the cake’s flavor profile.
- 1/4 cup plus 2 tablespoons 2% milk: Provides additional moisture for the frosting.
- 5 tablespoons unsweetened cocoa powder (I used Hershey’s dark): This is for the frosting, ensuring it maintains that intense chocolate flavor.
- 1 stick salted butter, softened: Ensures a smooth consistency for the frosting when whipped in.
- 3 3/4 cups powdered sugar: Adds sweetness and structure to the frosting.
- 1/2 teaspoon pure vanilla extract: This adds a lovely aroma and taste to the frosting.
How to Make Texas Sheet Cake
- Preheat the Oven: Set your oven to 350 degrees F. Spray a 13 x 17 1/2 inch jelly roll pan with cooking spray or line it with tin foil for easy removal.
- Melt the Butter: In a medium saucepan over medium heat, place 2 sticks of salted butter. Let the butter melt, then slowly stir in 1 cup of water and 7 tablespoons of cocoa powder until you achieve a smooth mixture. Stir until it comes to a light boil, and then remove from heat. Allow the mixture to cool for about 10 minutes.
- Combine Dry Ingredients: In a large mixing bowl, mix together 2 cups of all-purpose flour, 2 cups of granulated sugar, 1 teaspoon of baking soda, and 3/4 teaspoon of kosher salt.
- Mix Wet Ingredients: In a small bowl, whisk together 2/3 cup of buttermilk, 2 large eggs, and 1 teaspoon of pure vanilla extract.
- Combine the Mixtures: Slowly pour the cooled chocolate mixture into the dry ingredients while stirring, incorporating it in three parts to ensure a smooth batter. Make sure everything is blended well.
- Bake: Pour the luscious batter into the prepared jelly roll pan and bake for 18-20 minutes until a toothpick comes out clean from the center.
- Prepare the Frosting: About 5 minutes before the cake is done, start making the icing. In a large saucepan over medium heat, whisk together 1/4 cup plus 2 tablespoons of milk and 5 tablespoons of cocoa powder. Stir in 1 stick of softened salted butter and bring it to a boil. Once it’s boiling, turn off the heat and gradually whisk in 3 3/4 cups of powdered sugar until you have a smooth frosting.
- Frost the Cake: As soon as the cake comes out of the oven, pour the warm icing over it, spreading evenly over the top and sides.
- Cool and Serve: Allow the cake to cool for about 20 minutes before cutting it into squares. A plastic knife works wonders here, helping you cut through the cake without any sticking.
Storing & Reheating
To store your Texas Sheet Cake, place it in an airtight container at room temperature for up to 3 days. If you need a longer shelf life, refrigerate it for up to a week. For longer storage, you can freeze the cake for up to 3 months; just wrap it tightly in plastic wrap and then aluminum foil to prevent freezer burn. For a delightful treat, thaw the cake in the fridge overnight and serve it at room temperature, or gently reheat slices in the microwave for about 10-15 seconds.
Chef’s Helpful Tips
- To prevent a dry cake, avoid overmixing the batter; stop mixing just when combined.
- Ensure your eggs and buttermilk are at room temperature for better emulsification.
- If you’re unsure about doneness, check a few minutes earlier; you want a slight spring back when touched.
- If your frosting thickens too much, add a splash of milk to loosen it up while whisking.
- For an extra layer of flavor, experiment with adding chopped nuts or a sprinkle of sea salt on top of the frosting!
Don’t shy away from exploring new flavor combinations with the Texas Sheet Cake. Whether you want to add a hint of espresso, experiment with different frostings like cream cheese or caramel, or even fold in some chocolate chips to the batter, the possibilities are endless!
