Ingredients:
For the Cake:
- 2 cups sugar: Sugar adds sweetness and helps to create a tender crumb.
- 2 cups all-purpose flour: Flour provides structure to the cake. For a gluten-free version, you can substitute with a gluten-free flour blend.
- 1/4 teaspoon salt: Salt enhances the flavor of the cake and balances the sweetness.
- 1/2 cup buttermilk: Buttermilk adds moisture and a slight tang to the cake. It also helps to activate the baking soda, resulting in a lighter texture.
- 1 teaspoon baking soda: Baking soda is a leavening agent that helps the cake rise.
- 2 large eggs: Eggs add richness and structure to the cake. They also help to bind the ingredients together.
- 1 teaspoon vanilla extract: Vanilla adds depth of flavor and complements the chocolate.
- 1/2 cup unsalted butter: Butter adds moisture and flavor. For a dairy-free option, you can use plant-based margarine.
- 1/2 cup vegetable oil: Oil helps to keep the cake moist and tender.
- 4 tablespoons cocoa powder: Cocoa powder provides the rich chocolate flavor. You can use either natural or Dutch-processed cocoa powder.
- 1 cup boiling water: Boiling water helps to bloom the cocoa powder, intensifying the chocolate flavor.
For the Frosting:
- 1/2 cup unsalted butter: Butter provides a creamy base for the frosting.
- 4 tablespoons cocoa powder: Cocoa powder gives the frosting its chocolate flavor.
- 6 tablespoons milk: Milk helps to achieve the right consistency for the frosting. You can use any type of milk, including dairy-free alternatives.
- 1 teaspoon vanilla extract: Vanilla enhances the flavor of the frosting.
- 1 pound powdered sugar: Powdered sugar sweetens the frosting and helps to create a smooth texture.
- 1/2 cup chopped pecans (optional): Pecans add a crunchy texture and nutty flavor to the frosting.
Directions:
For the Cake:
- Preheat the Oven: Preheat your oven to 350°F (175°C). This ensures that the cake will bake evenly. Grease and flour a sheet cake pan to prevent the cake from sticking.
- Prepare the Dry Ingredients: In a large mixing bowl, combine the sugar, flour, and salt. Mixing the dry ingredients first helps to evenly distribute the salt and ensures a uniform texture in the cake.
- Mix the Wet Ingredients: In a separate small bowl, mix together the buttermilk, baking soda, eggs, and vanilla extract. This mixture will help to activate the baking soda and create a light, fluffy cake.
- Prepare the Chocolate Mixture: In a medium saucepan, melt the butter with the vegetable oil and cocoa powder over medium heat, stirring constantly until smooth. Remove from heat and stir in the boiling water. This step blooms the cocoa, intensifying the chocolate flavor.
- Combine the Ingredients: Pour the chocolate mixture into the dry ingredients and mix until combined. Then, add the buttermilk mixture and stir until smooth. The batter should be thick and glossy.
- Bake the Cake: Pour the batter into the prepared sheet cake pan and spread it evenly. Bake for 20 minutes, or until a toothpick inserted into the center comes out clean. The cake should be slightly springy to the touch.
For the Frosting:
- Prepare the Frosting Base: In a medium saucepan, melt the butter and cocoa powder over medium heat, stirring until smooth. This creates a rich, chocolatey base for the frosting.
- Add the Liquid Ingredients: Add the milk and vanilla extract, stirring until combined. The mixture should be smooth and glossy.
- Incorporate the Sugar: Gradually add the powdered sugar, stirring until the frosting is smooth and free of lumps. The frosting should be thick enough to spread easily, but not so thick that it becomes difficult to work with.
- Finish with Pecans: Remove the frosting from heat and stir in the chopped pecans, if using. The pecans add a delightful crunch and enhance the flavor of the frosting.
- Frost the Cake: Pour the frosting over the warm cake, spreading it evenly with a spatula. Allow the frosting to set slightly before cutting the cake into squares.
Tips for Success
- Measure Ingredients Accurately: Baking is a science, so it’s essential to measure your ingredients accurately. Use a kitchen scale for the most precise measurements, especially when measuring flour and sugar.
- Use Room Temperature Ingredients: Ensure that your eggs and buttermilk are at room temperature before mixing. This helps the ingredients to combine more easily and results in a smoother batter.
- Don’t Overmix the Batter: Overmixing can lead to a tough cake. Stir the ingredients until just combined to avoid developing too much gluten in the flour.
- Check for Doneness: Every oven is different, so keep an eye on your cake as it bakes. Test for doneness by inserting a toothpick into the center of the cake. If it comes out clean, the cake is done.
- Frost the Cake While Warm: Frosting the cake while it’s still warm allows the frosting to melt slightly and spread more easily. This creates a smooth, even layer of frosting that adheres well to the cake.
- Customize the Cake: Feel free to get creative with this recipe! You can add chocolate chips, nuts, or even a splash of coffee to the cake batter for an extra flavor boost. The frosting can also be customized with different extracts or by adding a pinch of salt to balance the sweetness.
Variations
While the classic chocolate sheet cake with frosting is delicious on its own, there are many ways to customize this recipe to suit your tastes and dietary needs. Here are a few variations to consider:
- Gluten-Free Chocolate Sheet Cake: Substitute the all-purpose flour with a gluten-free flour blend that contains xanthan gum. This will give the cake structure and prevent it from becoming too crumbly.
- Vegan Chocolate Sheet Cake: Replace the eggs with a flaxseed or chia seed egg substitute (1 tablespoon of ground flaxseed or chia seeds mixed with 3 tablespoons of water per egg). Use a dairy-free butter alternative and almond or soy milk in place of buttermilk.
- Chocolate Sheet Cake with Ganache: For a richer, more decadent cake, top it with a chocolate ganache instead of the classic frosting. To make ganache, heat 1 cup of heavy cream (or coconut cream for a dairy-free option) and pour it over 8 ounces of chopped dark chocolate. Let it sit for a few minutes, then stir until smooth. Pour the ganache over the cooled cake and let it set.
- Chocolate Peanut Butter Sheet Cake: Add 1/2 cup of creamy peanut butter to the frosting for a delicious chocolate-peanut butter combination. You can also swirl peanut butter into the cake batter before baking for an extra burst of flavor.
- Chocolate Sheet Cake with Cream Cheese Frosting: For a tangy contrast to the rich chocolate, frost the cake with cream cheese frosting. Beat 8 ounces of cream cheese with 1/2 cup of butter until smooth, then gradually add 4 cups of powdered sugar and 1 teaspoon of vanilla extract.
- Spiced Chocolate Sheet Cake: Add 1 teaspoon of cinnamon and 1/4 teaspoon of cayenne pepper to the dry ingredients for a spiced chocolate cake with a hint of warmth and complexity.
- Chocolate Sheet Cake with Berries: Top the frosted cake with fresh berries, such as strawberries, raspberries, or blueberries, for a burst of freshness and color. You can also fold chopped berries into the cake batter for added texture.
- Mocha Chocolate Sheet Cake: Replace the boiling water with freshly brewed coffee for a mocha-flavored cake. The coffee will enhance the chocolate flavor and add a subtle richness.
- Mint Chocolate Sheet Cake: Add 1/2 teaspoon of peppermint extract to the cake batter and the frosting for a refreshing mint chocolate version. Garnish the cake with crushed candy canes or mint leaves for a festive touch.
- Caramel Chocolate Sheet Cake: Drizzle caramel sauce over the frosted cake and sprinkle with a pinch of sea salt for a sweet and salty combination that’s sure to please.

10 FAQs
- Can I make this cake in advance? Yes, you can bake the cake a day in advance. Store it at room temperature, covered tightly, and add the frosting just before serving. This allows the cake to stay fresh, and the frosting can be applied smoothly.
- Can I freeze the chocolate sheet cake? Absolutely! You can freeze the unfrosted cake for up to 3 months. Wrap it tightly in plastic wrap and aluminum foil. Thaw it in the refrigerator overnight before frosting and serving. This is a great option if you want to prepare the cake ahead of time.
- What type of cocoa powder should I use? You can use either natural or Dutch-processed cocoa powder. Dutch-processed will give a deeper chocolate flavor and a darker color, while natural cocoa powder will provide a lighter, more traditional chocolate taste. Choose according to your preference.
- Can I make this recipe gluten-free? Yes, you can substitute the all-purpose flour with a gluten-free flour blend. Make sure the blend contains xanthan gum for better texture. This ensures that the cake remains moist and doesn’t fall apart.
- What can I substitute for buttermilk? If you don’t have buttermilk, you can make a substitute by mixing 1 tablespoon of lemon juice or white vinegar with 1 cup of milk. Let it sit for 5 minutes before using. This homemade buttermilk will work just as well in the recipe.
- How do I store the leftovers? Store leftover cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. This helps to keep the cake fresh and the frosting intact.

- What size pan should I use? This recipe is typically made in an 18×13-inch sheet cake pan, but you can use a 9×13-inch pan for a thicker cake. Just adjust the baking time accordingly. A smaller pan will result in a denser, more substantial cake.
- How can I make this cake dairy-free? To make the cake dairy-free, substitute the butter with a plant-based margarine and use a dairy-free milk alternative, such as almond milk or soy milk, mixed with lemon juice as a buttermilk substitute. This version of the cake is just as delicious and suitable for those with dairy allergies or intolerances.
