Ingredients You’ll Need

1 cup hot water or hot coffee: Using hot coffee intensifies the chocolate flavor, but hot water works just as well.
1 ¾ cups all-purpose flour: This helps provide structure. For gluten-free options, consider a good all-purpose gluten-free blend.
⅔ cup cocoa powder: Dutch-processed cocoa gives a deeper flavor; I recommend a high-quality cocoa like Dutch cocoa.
1 teaspoon baking powder: Incorporates a lightness to the cake.
1 teaspoon baking soda: This helps the cake rise beautifully.
1 ½ cups granulated sugar: Sweetens the cake perfectly and balances the cocoa bitterness.
¾ teaspoon salt: Enhances the flavors and balances sweetness.
½ cup vegetable oil: Sunflower oil is my top choice; it keeps the cake moist.
2 large eggs: Eggs provide richness and enrich the texture of the cake.
¼ cup full-fat plain yogurt: Adds moisture and a subtle tang, which is delightful in baked goods.
½ cup whole milk: Contributes to the cake’s delightful softness.
1 teaspoon pure vanilla extract: Vanilla rounds out the flavors with its fragrant sweetness.
10 ½ oz pure milk chocolate: Use good quality chocolate to ensure a delicious ganache.
⅓ cup light cream: This will create a luscious frosting; heavy cream can be used for an even richer texture.
1 tablespoon cocoa powder (optional): Use another splash to boost flavor; stick with the same Dutch cocoa.
2 tablespoons full-fat plain yogurt: This is added to the frosting for extra creaminess.
⅛ teaspoon salt: Just a pinch helps enhance the sweetness of the frosting.

How to Make Chocolate Texas Sheet Cake

Preheat the oven: Set your oven to 325°F. Prepare a 13×18 inch half-sheet pan by spraying it with cooking spray or greasing it lightly with butter. Don’t forget to line it with parchment paper—press it down well so it sticks. The batter can be quite runny, so securing the parchment is crucial.
Prepare the liquid: Boil a kettle of water and keep it warm. If you choose to use coffee, that’ll add a lovely depth to the chocolate flavor.
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 until everything is combined thoroughly.
Combine the wet ingredients: In a medium bowl, mix together 2 large eggs, ½ cup vegetable oil, ¼ cup full-fat plain yogurt, ½ cup whole milk, and 1 teaspoon pure vanilla extract. Whisk until well blended, then pour into the bowl of dry ingredients.
Blend together: Use an electric handheld mixer on medium-low speed to mix everything until just combined; if you prefer, you can do this by hand with a whisk. The mixture will be somewhat thick at this point.
Incorporate the hot liquid: Gradually pour in the hot water or coffee in two stages, mixing well after each addition. The batter will be quite thin, which is perfect.
Bake the cake: Pour the batter into your prepared pan, giving it a light tap on the counter to release any large air bubbles. Bake for 25-28 minutes or until a skewer inserted into the center comes out clean, and the cake springs back when lightly pressed. Allow the pan to cool completely on a wire rack.
Make the icing: Finely chop 10 ½ oz of milk chocolate and place it into a heatproof bowl. If using chocolate chips, no need to chop them.
Heat the cream: In a 1-quart saucepan, pour in ⅓ cup of light cream and bring it to a gentle boil over medium-low heat. Once boiling, remove it from heat and pour it over the chopped chocolate. Cover the bowl and let it stand for 2 minutes before stirring.
Finish the ganache: Gently stir the chocolate and cream until it becomes smooth and glossy. Gradually sift in 1 tablespoon cocoa powder, adding 2 tablespoons of full-fat plain yogurt and ⅛ teaspoon salt. Mix gently to avoid incorporating air, which can cause the ganache to split. Set aside to cool for about 20-30 minutes until it thickens slightly.
Frost the cake: Once the ganache has thickened to the consistency of custard, pour it over the cooled cake. Spread it out evenly. Let the cake rest in the fridge for about 15-20 minutes to allow the icing to set before slicing and serving.

Storing & Reheating

You can store any leftovers of Chocolate Texas Sheet Cake at room temperature, covered, for up to 3 days. If storing in the fridge, use an airtight container to keep it fresh for about a week. For longer storage, consider freezing it! Slice the cake and wrap individual pieces tightly in plastic wrap and foil, then store them in the freezer for up to 3 months. When you’re ready to enjoy, just thaw the slices at room temperature. The texture might change slightly, but you can refresh it by warming a slice in the microwave for about 10 seconds.

Chef’s Helpful Tips

Avoid overmixing the batter as this can lead to a denser cake. Mix until just combined.
Ensure all your wet ingredients are at room temperature for the best texture.
If your ganache is too thin, give it a bit more time to cool and thicken before spreading.
For a fun twist, add chopped nuts or chocolate chips to the batter for extra texture.
You can bake the cake a day ahead. Just frost it on the day you plan to serve it for the freshest taste.

There’s something undeniably special about Chocolate Texas Sheet Cake. Its rich chocolate flavor and tender sponge make it a dessert that brings people together, whether it’s a festive holiday or an ordinary weeknight. Feel free to experiment and make it your own.
