Ingredients You’ll Need

1 cup hot water or hot coffee: It activates the cocoa and enhances the chocolate flavor, making your cake even richer.
1 ¾ cups all-purpose flour: This forms the structure of the cake, keeping it fluffy. You can use a gluten-free blend if desired.
⅔ cup cocoa powder: Dutch cocoa is preferable for a deeper chocolate flavor but any unsweetened cocoa will do.
1 teaspoon baking powder: Helps the cake rise, giving it that airy texture.
1 teaspoon baking soda: Works with acidic ingredients to provide lift.
1 ½ cups granulated sugar: Sweetens the cake and balances the bittersweet chocolate.
¾ teaspoon salt: Enhances all the flavors and balances the sweetness.
½ cup vegetable oil: Keeps the cake moist. Sunflower oil is a great choice here, but you can use melted butter for extra richness.
2 large eggs: Binds the ingredients together and adds moisture.
¼ cup full-fat plain yogurt: Adds richness and improves the cake’s moisture; sour cream works well too.
½ cup whole milk: Contributes to the cake’s texture and flavor.
1 teaspoon pure vanilla extract: Enhances the overall flavor.
10 ½ oz pure milk chocolate: The star of the frosting, resulting in a silky smooth ganache.
⅓ cup light 10% cream: Helps create a luscious icing; half-and-half can be a substitute.
1 tablespoon cocoa powder (optional): Enhances the flavor of the ganache if desired.
2 tablespoons full-fat plain yogurt: For creaminess in the frosting.
⅛ teaspoon salt: Balances the sweetness in the frosting.

How to Make Chocolate Texas Sheet Cake

Prepare the Pan: Preheat your oven to 325°F. Lightly grease a 13 x 18 inch half-sheet pan with cooking spray or butter. Make sure to line it with parchment paper for easy removal. This cake batter is quite runny, so ensure the parchment is well-secured to avoid any leaks.
Prep the Liquid: Boil a kettle of water. If you’re using coffee for the added depth, brew it and keep it warm.
Mix the Dry Ingredients: In a large bowl, sift together 1 ¾ cups all-purpose flour, ⅔ cup cocoa powder, 1 teaspoon baking powder, and 1 teaspoon baking soda. Add in 1 ½ cups granulated sugar and ¾ teaspoon salt, whisking everything to ensure even blending.
Combine the Wet Ingredients: In a medium bowl, whisk together 2 large eggs, ½ cup vegetable oil, ¼ cup full-fat plain yogurt, ½ cup whole milk, and 1 teaspoon pure vanilla extract until smooth. Pour this mixture into the bowl with the dry ingredients and mix using an electric mixer on medium-low until combined. Alternatively, mix by hand with a wire whisk if you prefer.
Incorporate the Hot Liquid: Gradually add the hot water or coffee into the batter in two stages, keeping the batter smooth and lump-free. Don’t worry; the batter will be quite thin and runny.
Bake the Cake: Pour the batter into the prepared pan, giving it a gentle tap against the counter to release any large air bubbles. Bake for 25-28 minutes, or until the cake springs back softly when pressed and a toothpick inserted into the center comes out clean. Once baked, transfer it to a wire rack and allow it to cool completely.
Prepare the Frosting: Finely chop the 10 ½ oz milk chocolate and place it in a heatproof bowl (unless using couverture chocolate chips).
Heat the Cream: In a saucepan, bring ⅓ cup light cream to a gentle boil over medium-low heat. Once boiling, remove from heat and pour the cream over the chopped chocolate. Allow it to sit covered for 2 minutes before stirring gently in circular motions until it’s smooth and glossy.
Add Additional Ingredients: Sift in 1 tablespoon of cocoa powder (if using), and add in 2 tablespoons of full-fat plain yogurt and ⅛ teaspoon salt. Mix gently to incorporate, avoiding vigorous whisking to prevent the ganache from splitting.
Frost the Cake: Allow the ganache to thicken slightly for 20-30 minutes, reaching a custard-like consistency. Pour it over the cooled cake, spreading it out evenly. Chill the cake in the refrigerator for 15-20 minutes to allow the icing to set. Once ready, slice and serve!

Storing & Reheating

To keep your Chocolate Texas Sheet Cake fresh, store it covered at room temperature for up to 3 days. For longer storage, transfer it to the refrigerator where it will last for about a week. If you need to freeze it, wrap the cake tightly in plastic wrap or foil, and it will hold well for up to three months. When you’re ready to enjoy, simply thaw it at room temperature and, if desired, reheat it in a microwave for a few seconds to restore that signature moistness.

Chef’s Helpful Tips

Keep your ingredients at room temperature for best results—especially the eggs and yogurt.
Avoid overmixing to maintain a light texture in the cake.
If your frosting seems too runny, let it cool longer before pouring.
If you’re experimenting, add a splash of espresso to the batter for an even richer chocolate taste!
For a fun twist, sprinkle chopped nuts or chocolate chips on top of the frosting for added texture.

Chocolate Texas Sheet Cake is not just a treat; it’s a slice of joy shared among friends and family. With its rich flavor, luscious frosting, and inviting appearance, it’s bound to be a favorite. Don’t hesitate to try it out, whether for a birthday party or just a midweek pick-me-up. You’ll discover that this recipe is as delightful to make as it is to eat!

Recipe FAQs

Can I use Dutch-process cocoa powder?
