Ingredients

Let’s keep this Texas Sheet Cake simple and stress-free. Everything here is easy to find, and the ingredient list is built to deliver that ultra-moist chocolate sheet cake texture plus the classic warm poured frosting everyone loves.

For the Chocolate Sheet Cake

2 cups (250 g) all-purpose flour

2 cups (400 g) granulated sugar

1/2 cup (45 g) unsweetened cocoa powder (natural or Dutch-process both work)

1 tsp baking soda

1/2 tsp fine salt

2 large eggs (room temperature helps the batter blend smoothly)

1/2 cup (120 ml) buttermilk (for tenderness and a subtle tang)

1 tsp vanilla extract

1 cup (226 g) unsalted butter

1 cup (240 ml) water

For the Warm Poured Chocolate Frosting

1/2 cup (113 g) unsalted butter

1/4 cup (22 g) unsweetened cocoa powder

1/3 cup (80 ml) milk (whole milk is richest, but any milk works)

1 tsp vanilla extract

3 1/2 cups (420 g) powdered sugar (sifted if lumpy)

1 cup (120 g) chopped pecans (optional)

Quick ingredient notes (so you get perfect results)

Cocoa powder: If you want a deeper, darker chocolate vibe, go Dutch-process. If you want the most classic “school bake sale” flavor, use natural cocoa.

Buttermilk substitute: No buttermilk? Mix 1/2 cup milk + 1 1/2 tsp vinegar or lemon juice, let it sit 5 minutes, then use as directed.

Powdered sugar: If it’s clumpy, a quick sift makes your chocolate icing silky instead of grainy.

Once you’ve got these measured, the rest moves fast—this is truly a one-pan chocolate sheet cake situation, and you’ll be frosting it before you know it.

Instructions

This Texas Sheet Cake comes together quickly, so it helps to have everything measured and ready. The best part? You’ll pour the warm chocolate frosting over the cake while it’s still warm—this is what gives that signature fudgy finish.

1) Prep your pan and oven

Preheat your oven to 350°F (175°C).

Grease a rimmed baking sheet/jelly roll pan (about 18×13 inches) and line it with parchment if you want extra-easy lifting and clean slices.

Quick tip: A rimmed pan matters here—this chocolate sheet cake batter is thin and needs edges.

2) Mix the dry ingredients

In a large bowl, whisk together:

flour

sugar

cocoa powder

baking soda

salt

Whisking now prevents cocoa pockets later and keeps the crumb even.

3) Warm the cocoa-butter mixture

In a saucepan over medium heat, melt butter with the water.

Once melted, whisk in the cocoa powder until smooth.

Bring it just to a gentle simmer, then remove from heat.

You’re not trying to “boil” it hard—just warm and glossy so it blends easily.

4) Combine the batter (smooth, not overmixed)

Pour the warm cocoa mixture into the bowl of dry ingredients.

Stir until the batter looks evenly chocolatey.

Add the eggs, buttermilk, and vanilla, then mix until smooth.

Friend-to-friend guidance: Mix only until everything comes together. Overmixing can make a cake bake up tougher instead of tender and ultra-moist.

5) Bake

Pour the batter into your prepared pan and spread it into an even layer.

Bake for 18–22 minutes, or until:

the center springs back lightly when touched, and

a toothpick comes out with a few moist crumbs (not wet batter).

Don’t chase “bone dry.” Pulling it at the right moment is the secret to a truly moist chocolate sheet cake.

6) Make the warm poured frosting

While the cake bakes (or as it comes out), make the frosting:

In a saucepan, melt butter with milk.

Whisk in the cocoa powder until smooth.

Remove from heat and stir in vanilla.

Gradually whisk in powdered sugar until glossy and pourable.

Fold in pecans if using.

Consistency check: It should flow like thick chocolate sauce. If it feels too thick, add 1–2 teaspoons milk. If too thin, add a spoonful of powdered sugar.

7) Frost while warm, then let it set

As soon as the cake comes out of the oven, pour the frosting over the warm surface.

Gently spread it to the edges with an offset spatula or the back of a spoon.

Let it rest 15–30 minutes so the frosting can settle into that soft, fudgy layer—then slice and serve.

That’s it—simple steps, one pan, and the classic Texas Sheet Cake payoff every time.

Pro Tips and Variations

This Texas Sheet Cake is wonderfully forgiving, but a few small moves can take it from “really good” to best ever. Here are the tips I rely on every time I want that ultra-moist chocolate sheet cake texture and a smooth, fudgy finish.

Pro Tips for the Best Texture and Flavor

Measure flour the gentle way: Spoon flour into the measuring cup, then level it off. Packing it down can add extra flour and make the cake less tender.

Whisk cocoa well: Cocoa likes to clump. A good whisk (or a quick sift) helps you avoid dry pockets and keeps the crumb evenly chocolatey.

Don’t overmix once the eggs go in: Stir just until the batter looks smooth. Overmixing can make a sheet cake bake up a little chewy instead of soft.

Pull it at “moist crumbs,” not dry: For a truly moist chocolate cake, you want a toothpick to come out with a few damp crumbs. Wet batter = needs more time. Bone-dry toothpick = you may have gone too far.

Frost while the cake is warm: This is the signature move for a classic warm poured frosting. It melts slightly into the surface and sets into that glossy, fudgy layer.

Fix frosting consistency fast:

Too thick? Add 1–2 teaspoons milk at a time.

Too thin? Whisk in 1–2 tablespoons powdered sugar at a time.

Easy Flavor Variations (Choose Your Vibe)

Pecan classic: Stir in chopped pecans or sprinkle them on top right after frosting. Toasting them first makes the flavor pop.

Coffee-chocolate boost: Add 1–2 teaspoons espresso powder to the warm cocoa-butter mixture. It won’t taste like coffee—just deeper chocolate.

Mexican chocolate twist: Add 1/2–1 teaspoon cinnamon to the cake batter, and a tiny pinch to the frosting if you like.

Extra-dark and intense: Use Dutch-process cocoa for a richer color and a more “grown-up” chocolate profile.

Salted finish: Sprinkle a small pinch of flaky salt over the frosting while it’s still warm. The contrast is addictive.

Dietary and Practical Swaps

No buttermilk? Mix 1/2 cup milk + 1 1/2 teaspoons vinegar or lemon juice and let it stand for 5 minutes. You’ll still get that tender crumb.

Nut-free version: Simply skip the pecans. The frosting stays perfectly fudgy and smooth.

9×13 pan option: You can bake it in a 9×13, but it will be thicker, so expect a longer bake time. Start checking around 25 minutes and use the “moist crumbs” test.

Make-Ahead and Storage Tips

Make-ahead friendly: This chocolate sheet cake tastes even better after the frosting has had time to set and soften slightly into the top.

Clean slicing trick: Let the cake cool until the frosting is set, then use a long knife wiped clean between cuts for neat squares.

Pick one variation or keep it classic—either way, you’ll end up with that iconic Texas Sheet Cake look and the kind of chocolate flavor people remember.

Serving Suggestions

One of the best things about Texas Sheet Cake is how effortlessly it fits any occasion—from casual weeknight dessert to full-on party tray. Once the warm poured frosting has set into that fudgy layer, you can serve it simple or dress it up in seconds.

The best way to serve it

Slightly warm (my favorite): Let the cake rest long enough for the frosting to set, then serve when the cake is still a little warm underneath. The top stays fudgy and the crumb tastes extra ultra-moist.

Room temperature (most classic): This is how it’s often served at gatherings—easy to slice, easy to plate, and still intensely chocolatey.

Chilled for a firmer bite: Pop slices in the fridge if you like a denser, brownie-like feel. The frosting becomes more structured and extra satisfying.

Toppings that make it feel special

Pick one—this chocolate sheet cake doesn’t need much:

Vanilla ice cream: The cold-and-warm contrast is unbeatable.

Whipped cream: Light, airy, and perfect if you want to balance the rich cocoa flavor.

Fresh berries (strawberries or raspberries): Adds brightness and makes the cake feel “fancy” with almost zero effort.

Toasted pecans: If you skipped nuts in the frosting, a sprinkle on top adds crunch without changing the texture of the icing.

A dusting of cocoa or powdered sugar: Quick, pretty, and great for photos.

Drinks that pair beautifully

Coffee or espresso: Brings out the deep chocolate notes (especially if you used espresso powder).

Cold milk: Simple, nostalgic, and always a hit with kids.

Hot tea: A cozy pairing when you want dessert without feeling too heavy.

Serving for a crowd (clean slices, no stress)

If you’re taking this potluck dessert anywhere, here’s the easiest approach:

Let the frosting set 20–30 minutes so it doesn’t smear.

Use a long knife, and wipe it between cuts for neat squares.

Serve straight from the pan—this is exactly what a sheet cake is made for.

Whether you keep it plain or add a scoop of ice cream, this Texas Sheet Cake is the kind of dessert that looks generous, tastes indulgent, and feels instantly celebratory.

Conclusion

If you’re looking for a dessert that’s easy, dependable, and guaranteed to make people smile, this Texas Sheet Cake is it. You get a soft, ultra-moist chocolate sheet cake with a deep cocoa flavor—then you finish it the classic way with that glossy, warm poured frosting that sets into a fudgy top layer.

Before you go, here are the three little reminders that make it “best ever” every time:

Don’t overbake: Pull it when the center gives you moist crumbs, not a dry toothpick.

Frost while warm: That’s the signature move for the smoothest chocolate icing and the most irresistible finish.

Keep it simple: This cake shines on its own, but it also welcomes pecans, cinnamon, or a scoop of vanilla ice cream.

Bake it once and you’ll understand why it’s such a beloved crowd-pleaser—perfect for potlucks, birthdays, or any day you want a big pan of chocolate happiness.
