A rich and moist chocolate sheet cake with buttermilk is one of the most beloved comfort desserts across the United States. This timeless treat combines rich cocoa flavors, fluffy texture, and a touch of tangy buttermilk to create a dessert that is perfect for any occasion—birthdays, family gatherings, or simple weeknight indulgences. Today, we invite you to explore this incredibly delicious recipe and learn all the secrets for making the best chocolate sheet cake with buttermilk.
Why Buttermilk Makes the Difference
When it comes to making an exceptional cake, buttermilk is a game-changer. Buttermilk provides a slightly tangy flavor that complements the richness of the chocolate while enhancing the cake’s overall moisture and tenderness. You might wonder, why do you put buttermilk in a cake? The answer lies in its acidity. The buttermilk reacts with the baking soda to create a fluffy and tender crumb, which is the hallmark of a truly fantastic cake.
The acidity in buttermilk also breaks down the gluten in the flour, resulting in a softer texture. This means that every bite of your cake will melt in your mouth. Moreover, buttermilk adds a layer of complexity to the flavor, enhancing the cocoa and balancing the sweetness. For anyone who has baked with buttermilk before, it’s no secret that this ingredient can elevate any baked good to the next level.

What Is a Texas Chocolate sheet cake with buttermilk?
The Texas sheet cake, as it is often known, is an iconic type of chocolate sheet cake. Why do they call it a Texas sheet cake? It’s said to have originated in Texas, and the name might also reference the sheer size of the cake, as Texans are known for their love of large-scale creations. With its characteristic rich chocolate frosting poured over the warm cake, this dessert has become synonymous with Southern hospitality and comfort.
The Texas sheet cake is baked in a large, shallow pan, making it ideal for serving a crowd. Its popularity extends beyond Texas, and today, it is a beloved dessert across the U.S. If you’re interested in learning more about the history of Texas sheet cakes, check out this informative piece on Southern Living.
The Unique Characteristics of a Texas Sheet Cake
Texas sheet cakes are known for their moist, almost fudgy texture, which makes them stand apart from traditional chocolate cakes. The use of boiling water in the batter helps to bloom the cocoa, bringing out a deeper chocolate flavor. The frosting, often poured over the cake while it is still warm, creates a glossy, almost candy-like coating that seeps into the cake and makes every bite rich and indulgent.
Another unique characteristic is the quick preparation time. Unlike layered cakes that require baking multiple layers and assembling them with frosting, a Texas sheet cake is straightforward. It’s baked in a single layer, and the frosting is simply poured over the top. This makes it perfect for those who want a delicious cake without spending hours in the kitchen.
The Importance of Serving Size and Versatility Chocolate Sheet Cake
One of the reasons why Texas sheet cake is so popular is its versatility and ability to serve a large number of people. Whether you’re hosting a birthday party, a potluck, or a family reunion, this cake can easily feed a crowd. The large, flat shape makes it easy to cut into small or large pieces, depending on the number of guests.
Moreover, the cake can be customized to suit different tastes. Some people add chopped pecans or walnuts to the frosting for a crunchy texture, while others prefer to keep it smooth. You can even add a sprinkle of sea salt on top of the frosting to create a sweet-and-salty contrast that elevates the flavor profile.
The Key Ingredients for a Perfect Chocolate Sheet Cake with Buttermilk
To make a truly outstanding chocolate sheet cake with buttermilk, you’ll need a combination of simple yet high-quality ingredients. Let’s break down what you’ll need and why each ingredient is crucial for the success of your cake.
Ingredients
- All-purpose flour: Provides the structure for the cake. The gluten in the flour helps the cake hold its shape while still being tender.
- Granulated sugar: Adds sweetness and helps create a tender crumb. The sugar also helps to retain moisture, ensuring that the cake doesn’t dry out.
- Unsweetened cocoa powder: The star of the show, bringing in that rich, chocolatey flavor. Use a high-quality cocoa powder for the best results, as it will greatly impact the taste of your cake.
- Baking soda: Reacts with the buttermilk to make the cake rise. The baking soda helps to create a light, fluffy texture by releasing carbon dioxide when it interacts with the acidic buttermilk.
- Salt: Enhances the flavors. A pinch of salt balances the sweetness and brings out the richness of the chocolate.
- Unsalted butter: Adds richness and moisture. Butter also contributes to the flavor and helps create a tender crumb. Using unsalted butter allows you to control the amount of salt in the recipe.
- Buttermilk: Adds tanginess and helps make the cake moist and tender. The acidity in buttermilk breaks down the gluten in the flour, resulting in a softer texture.
- Eggs: Bind the ingredients together, adding structure and fluffiness. Eggs also add moisture and richness to the cake.
- Vanilla extract: Complements the chocolate flavor. A good-quality vanilla extract enhances the overall taste of the cake and adds depth to the chocolate.
- Boiling water: Helps bloom the cocoa powder for an extra depth of flavor. The boiling water intensifies the chocolate flavor and makes the cake batter smooth and easy to mix.
For the Frosting Chocolate Sheet Cake
- Unsalted butter: Provides a creamy base for the frosting. The butter gives the frosting its rich, smooth texture.
- Unsweetened cocoa powder: Adds that rich, chocolatey goodness. Just like in the cake, the quality of the cocoa powder matters for the frosting.
- Buttermilk: Keeps the frosting tangy and smooth. The buttermilk also helps to create a glossy finish on the frosting.
- Powdered sugar: Sweetens and thickens the frosting. Powdered sugar dissolves easily, ensuring a smooth, creamy frosting without any graininess.
- Vanilla extract: Enhances the overall flavor. The vanilla adds a warm, aromatic note that complements the chocolate.
- Chopped pecans (optional): Adds a nice crunch and texture. Pecans are a classic addition to Texas sheet cake frosting, adding both flavor and a pleasing crunch.
Ingredient Quality Matters Chocolate sheet cake with buttermilk
When making a chocolate sheet cake with buttermilk, the quality of the ingredients you use will directly impact the final result. Here are a few tips to ensure you’re using the best ingredients:
- Cocoa powder: opt for a high-quality, unsweetened cocoa powder. The flavor of the cocoa will be the dominant taste in the cake, so it’s worth using a good one. Dutch-processed cocoa powder will give you a darker color and a smoother, less acidic taste, while natural cocoa powder will have a more intense chocolate flavor.
- Butter: Use unsalted, high-fat butter for the best results. European-style butter, which has a higher fat content, will give you a richer, more flavorful cake.
- Buttermilk: Fresh buttermilk is ideal, but if you don’t have any on hand, you can make a substitute by mixing one tablespoon of lemon juice or white vinegar with one cup of milk. Let it sit for about 10 minutes before using it in the recipe.
Step-by-Step Instructions for the Best Chocolate Sheet Cake with Buttermilk
Step 1: Preheat the Oven and Prepare the Pan Chocolate sheet cake with buttermilk
Preheat your oven to 350°F (175°C). Grease a 13×18-inch sheet pan or line it with parchment paper for easy removal. Properly preparing the pan is crucial to ensure that the cake doesn’t stick and can be easily removed once it’s baked.
Step 2: Mix the Dry Ingredients of Chocolate sheet cake with buttermilk
In a large mixing bowl, combine 2 cups of all-purpose flour, 2 cups of granulated sugar, 1/2 teaspoon of salt, and 1 teaspoon of baking soda. Whisk until well combined. This step ensures that the baking soda and salt are evenly distributed throughout the flour, which will help the cake rise evenly.
Step 3: Prepare the Wet Ingredients Chocolate sheet cake with buttermilk
In a saucepan over medium heat, melt 1 cup of unsalted butter. Once melted, whisk in 1/4 cup of unsweetened cocoa powder until smooth. Add 1 cup of boiling water to the mixture and allow it to come to a gentle boil, then remove from heat. This process blooms the cocoa powder, which enhances its flavor and gives the cake a rich, chocolatey taste.
In a separate bowl, whisk together 1/2 cup of buttermilk, 2 large eggs, and 2 teaspoons of vanilla extract. The eggs should be at room temperature, as this helps them incorporate more easily into the batter and results in a smoother texture.
Step 4: Combine the Wet and Dry Mixtures of Chocolate sheet cake with buttermilk
Pour the warm cocoa mixture into the bowl with the dry ingredients and mix until well combined. The batter will be thin at this stage, but that’s what makes the cake so moist. Next, add the buttermilk mixture and continue mixing until the batter is smooth and free of lumps. Be careful not to overmix, as this can result in a dense cake.
Step 5: Bake the Chocolate sheet cake with buttermilk
Pour the batter into the prepared sheet pan, spreading it evenly. Bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean. Do not overbake, as this can make the cake dry. The cake should spring back slightly when touched, indicating that it is done.
Step 6: Make the Frosting Chocolate sheet cake with buttermilk
While the cake is baking, prepare the frosting. In a saucepan over medium heat, melt 1/2 cup of unsalted butter. Stir in 1/4 cup of unsweetened cocoa powder and 1/3 cup of buttermilk. Allow the mixture to come to a gentle boil, then remove from heat. Gradually whisk in 4 cups of powdered sugar and 1 teaspoon of vanilla extract until smooth. If you like, fold in 1 cup of chopped pecans for extra texture.
Step 7: Frost the Cake Chocolate sheet cake with buttermilk
Once the cake is out of the oven, let it cool for about 10 minutes. While the cake is still warm, pour the frosting over the top, spreading it evenly to cover the entire surface. Allow the cake to cool completely before serving. Frosting the cake while it’s still warm allows the frosting to seep into the cake slightly, creating a moist and flavorful experience with every bite.
Step 8: Serving Suggestions Chocolate sheet cake with buttermilk
This chocolate sheet cake with buttermilk is perfect on its own, but you can also serve it with a dollop of whipped cream or a scoop of vanilla ice cream. For a touch of elegance, consider adding a few fresh berries or a drizzle of caramel sauce on the side.
Tips for Making the Best Chocolate Sheet Cake with Buttermilk
- Use high-quality cocoa powder: The quality of your cocoa powder makes a significant difference in the flavor of your cake. Look for a cocoa powder with a rich, deep color and a strong chocolate aroma.
- Do not overmix: When combining the wet and dry ingredients, mix just until they are incorporated to avoid a dense cake. Overmixing can develop too much gluten, which will make the cake tough.
- Frost while warm: Pouring the frosting over a warm cake allows it to seep into the surface slightly, making every bite extra moist and flavorful. The warmth of the cake helps the frosting spread more easily and creates a smooth, glossy finish.
- Room temperature ingredients: Using room temperature eggs and buttermilk helps them incorporate more smoothly into the batter, resulting in a more even texture.
- Measure accurately: Baking is a science, and accurate measurements are crucial for success. Use a kitchen scale if possible to measure your ingredients by weight, especially the flour and sugar.
- Don’t skip the boiling water: Adding boiling water to the cocoa powder blooms it, bringing out the fullest, richest chocolate flavor. This step is essential for achieving the deep chocolate taste that makes this cake so special.
Sheet Cake vs. Regular Cake: What’s the Difference?
What’s the difference between sheet cake and regular cake? The main difference lies in the size and shape. A sheet cake is baked in a large, flat pan, making it easy to cut into squares and serve a crowd. It’s typically more casual than a layered cake, which is often round and stacked with frosting between the layers. The simplicity of a sheet cake makes it ideal for potlucks, picnics, and gatherings.
Another advantage of sheet cakes is that they bake faster due to their shallow depth. This means you can enjoy your cake sooner and with less fuss compared to a layered cake. Additionally, sheet cakes are much easier to decorate. The frosting is simply poured or spread over the top, whereas layered cakes require more intricate assembly and decorating skills.
Sheet cakes are also more versatile when it comes to serving sizes. You can cut them into small squares for a large gathering or into larger pieces for a more indulgent dessert. They’re perfect for any occasion where you need a dessert that’s easy to transport and serve.
Can You Substitute Buttermilk for Milk in Cakes?
Can I use buttermilk instead of milk in cake? Absolutely! Buttermilk adds an extra layer of tanginess and moisture that elevates the flavor profile of the cake. If you’re substituting buttermilk for regular milk, remember to add 1/2 teaspoon of baking soda for every cup of buttermilk to help with the rise.
Buttermilk’s acidity is what makes it such a valuable ingredient in baking. It reacts with baking soda to create carbon dioxide, which helps the cake rise and gives it a light, airy texture. This is especially important in chocolate cakes, where the acidity of the buttermilk also helps to enhance the cocoa flavor, making the cake taste even more chocolatey.
If you don’t have buttermilk on hand, you can easily make a substitute by adding 1 tablespoon of lemon juice or white vinegar to 1 cup of milk. Let it sit for about 10 minutes until it thickens slightly. This homemade version of buttermilk works well in most recipes, though the flavor might not be quite as rich as using real buttermilk.
Variations and Customizations Chocolate sheet cake with buttermilk
One of the best things about a chocolate sheet cake with buttermilk is how versatile it is. Here are some ideas for customizing your cake to suit your tastes or the occasion:
Add Mix-ins
- Chopped Nuts: Add chopped walnuts, pecans, or almonds to the cake batter or the frosting for extra crunch and flavor.
- Chocolate Chips: Fold in 1 cup of chocolate chips to the batter for an even more indulgent chocolate experience. You can use semi-sweet, dark, or even white chocolate chips.
- Shredded Coconut: For a tropical twist, add 1/2 cup of shredded coconut to the batter. Coconut pairs beautifully with chocolate and adds a chewy texture.
Frosting Variations
- Peanut Butter Frosting: Swap out the chocolate frosting for a creamy peanut butter frosting. The combination of chocolate and peanut butter is always a crowd-pleaser.
- Cream Cheese Frosting: For a tangy contrast to the rich chocolate, try using a cream cheese frosting. The cream cheese adds a delightful creaminess that pairs perfectly with the chocolate cake.
- Mocha Frosting: Add 1 tablespoon of instant coffee granules to the frosting to create a mocha flavor. The coffee enhances the chocolate flavor and adds a subtle, sophisticated twist.
Flavor Enhancements
- Espresso Powder: Add 1 teaspoon of espresso powder to the cake batter to enhance the chocolate flavor. Espresso powder intensifies the cocoa without adding a distinct coffee taste.
- Orange Zest: For a bright, citrusy twist, add 1 tablespoon of orange zest to the batter. Chocolate and orange are a classic combination that adds a refreshing note to the cake.
- Mint Extract: Replace the vanilla extract with 1/2 teaspoon of mint extract for a mint-chocolate cake. This is perfect for holidays or any time you’re craving the cool flavor of mint.
Serving Suggestions
- With Ice Cream: Serve each slice with a scoop of vanilla, chocolate, or coffee ice cream. The cold, creamy ice cream contrasts beautifully with the warm, rich cake.
- Whipped Cream and Berries: Top the cake with a dollop of freshly whipped cream and a handful of fresh berries such as strawberries, raspberries, or blueberries. The tartness of the berries cuts through the richness of the cake, creating a balanced and delightful dessert.
- Caramel Drizzle: Drizzle salted caramel sauce over the frosted cake for an extra layer of flavor. The combination of chocolate and caramel is irresistible.
Frequently Asked Questions Chocolate sheet cake with buttermilk
Why do you put buttermilk in a cake?
Buttermilk adds a tangy flavor and helps keep the cake moist. Its acidity also helps activate the baking soda, resulting in a tender and fluffy cake.

Additionally, buttermilk enhances the overall flavor of the cake, giving it a richer and more complex taste.
Why do they call it a Texas sheet cake?
The name likely comes from the cake’s origins in Texas or its large size, which is often associated with the saying, “Everything’s bigger in Texas.” The Texas sheet cake is known for being easy to make, serving a large number of people, and being incredibly delicious—all qualities that align with the generous spirit of Texas hospitality.

What’s the difference between sheet cake and regular cake?
A sheet cake is baked in a large, flat pan, making it ideal for serving a crowd, while regular cakes are usually round and layered.

Can I use buttermilk instead of milk in cake?
Yes, buttermilk can be used instead of milk, and it adds extra tanginess and moisture. Just remember to adjust the baking soda to help with the cake’s rise. The acidity of buttermilk makes it a great substitute for milk in most cake recipes, as it reacts with the leavening agents to create a light and tender crumb. If you don’t have buttermilk, you can make a substitute by adding lemon juice or vinegar to milk and letting it sit for a few minutes.
How do I store chocolate sheet cake with buttermilk?
To store your chocolate sheet cake with buttermilk, cover it tightly with plastic wrap or aluminum foil and keep it at room temperature for up to 3 days. If you live in a particularly warm climate, you may want to refrigerate the cake to prevent the frosting from becoming too soft.

Troubleshooting Common Issues Chocolate sheet cake with buttermilk
Why Is My Cake Dry?
If your chocolate sheet cake with buttermilk turns out dry, there are a few potential causes:
- Overbaking: The most common reason for a dry cake is overbaking. Be sure to check the cake for doneness at the 20-minute mark, and remove it from the oven as soon as a toothpick comes out clean.
- Incorrect Measurements: Too much flour can make the cake dry. Be sure to measure your flour correctly by spooning it into the measuring cup and leveling it off with a knife.
- Overmixing: Mixing the batter too much can develop the gluten in the flour, resulting in a tougher, drier cake. Mix just until the ingredients are combined.
Why Did My Frosting Turn Out Grainy?
Grainy frosting can be caused by undissolved powdered sugar or by overheating the frosting mixture.
- Undissolved Sugar: Be sure to sift the powdered sugar before adding it to the melted butter and cocoa mixture. This will help prevent lumps and ensure a smooth frosting.
- Overheating: If the frosting mixture gets too hot, the sugar can crystallize, resulting in a grainy texture. Be sure to remove the frosting from the heat as soon as it comes to a gentle boil.
How Do I Make My Cake Extra Moist?
To make your chocolate sheet cake with buttermilk extra moist, try the following tips:
- Add an Extra Egg Yolk: Adding an extra egg yolk to the batter can help make the cake richer and more moist.
- Use Oil Instead of Some Butter: Substitute part of the butter with vegetable oil. Oil stays liquid at room temperature, which helps keep the cake moist for longer.
- Don’t Overbake: Keep a close eye on the cake as it bakes, and remove it from the oven as soon as it’s done.
