Classic Texas Sheet Cake Rich, Fudgy & Irresistible

WANT TO SAVE THIS RECIPE?

There are chocolate cakes, and then there’s the Classic Texas Sheet Cake — unapologetically rich, unapologetically fudgy, and unmistakably Texan. This iconic dessert is a staple in Southern homes, bringing comfort, nostalgia, and sweet satisfaction to potlucks, celebrations, and weeknight cravings alike.

What makes Texas sheet cake so irresistible is its tender, melt-in-your-mouth texture and a glossy, poured-on chocolate icing that sets into a crackly, sugary crust. Every bite is soft, moist, and deeply chocolaty, with a whisper of cinnamon and the crunch of toasted pecans if you choose to add them. It’s not just a cake, it’s a memory waiting to be made.

Why You’ll Love This Classic Texas Sheet Cake

This cake isn’t fussy. No need for layers, special pans, or fancy decorations. It comes together in a single sheet pan and feeds a crowd with ease. The ingredients are simple pantry staples, but the result tastes like something truly special. It’s perfect for last-minute guests, holiday gatherings, or just because you’re craving chocolate in its most comforting form.

You’ll also love how quickly it bakes — and even faster disappears. Plus, the warm frosting is poured over the cake right after it comes out of the oven, soaking into the top and sealing in every bit of flavor and moisture.

What Kind of Cocoa Powder Should I Use?

Dutch-processed or natural cocoa powder both work here, but natural cocoa powder is more traditional and gives you that classic Southern richness. Make sure to use unsweetened cocoa powder. If you want to amp up the depth of flavor, try combining both types for a more layered chocolate taste. Just avoid using hot chocolate mix — it won’t give the same result.

Ingredients for the Classic Texas Sheet Cake

The charm of this cake is how little it asks of you. Each ingredient has a purpose, from creating the tender crumb to enhancing that nostalgic flavor we all love.

All-purpose flour gives the cake its structure and lightness.

Granulated sugar provides sweetness and helps keep the crumb tender.

Salt is essential to balance the richness and deepen the chocolate flavor.

Unsweetened cocoa powder brings the bold, dark chocolate taste that’s iconic in Texas sheet cake.

Baking soda reacts with the buttermilk to lift the cake without overpowering it.

Buttermilk adds moisture and a subtle tang that balances out the richness.

Eggs help bind everything together and give the cake a delicate structure.

Vanilla extract rounds out the flavors and enhances the chocolate.

Butter is used in both the cake and the frosting for richness and flavor.

Boiling water helps bloom the cocoa powder and creates a silky, pourable batter.

Chopped pecans are optional but traditional — they add texture and that signature Southern flair.

How To Make the Classic Texas Sheet Cake

Step 1: Prepare the Pan and Preheat the Oven

Grease a rimmed baking sheet (typically 10×15 inches or jelly roll pan) with butter or nonstick spray. Preheat your oven to 350°F so it’s ready when your batter is.

Step 2: Mix the Dry Ingredients

In a large mixing bowl, whisk together the flour, sugar, salt, and baking soda. Set aside while you prepare the wet ingredients.

Step 3: Heat the Butter and Cocoa

In a medium saucepan, combine butter, cocoa powder, and water. Bring to a boil while stirring constantly, then remove from heat and let it cool for a few minutes.

Step 4: Combine the Wet and Dry Mixtures

Pour the warm cocoa mixture over the flour mixture and stir until well combined. Add in the buttermilk, eggs, and vanilla, and mix until the batter is smooth.

Step 5: Bake the Cake

Pour the batter into the prepared sheet pan, spreading it evenly. Bake for 18–20 minutes or until a toothpick inserted into the center comes out clean.

Step 6: Make the Warm Frosting

Just before the cake is done baking, melt butter in a saucepan and stir in cocoa powder, then add milk and bring to a gentle simmer. Remove from heat and stir in powdered sugar and vanilla until smooth. Fold in the pecans if using.

Step 7: Frost the Cake While Warm

Pour the warm frosting directly over the hot cake and spread evenly. It will set into a glossy, crackly layer as it cools.

How to Serve and Store Classic Texas Sheet Cake

This cake is best served slightly warm or at room temperature when the frosting is still just a little gooey. It easily serves 18 to 24 people depending on how generously you slice it, making it a party favorite.

To store leftovers, cover the sheet pan tightly with foil or plastic wrap. It keeps well at room temperature for up to 3 days, or refrigerate it for longer freshness. The texture becomes denser and fudgier the next day — which some might say is even better.

What to Serve With Classic Texas Sheet Cake?

Fresh Berries

The brightness of strawberries or raspberries helps cut through the richness of the chocolate.

Cold Brew Coffee

That slightly bitter edge balances out the cake’s deep sweetness.

Vanilla Bean Ice Cream

A scoop on the side creates a hot-and-cold, creamy-and-fudgy combo no one can resist.

Salted Caramel Drizzle

If you’re feeling extra indulgent, a drizzle of caramel over each slice takes it over the top.

Glass of Milk

Classic and comforting, just like the cake.

Whipped Cream

Light and airy whipped cream adds a lovely contrast to the dense chocolate base.

Toasted Coconut

For a little texture and a nutty note, sprinkle some toasted coconut on top of each piece.
