- Prep Time: 20 minutes
- Cook Time: 30 minutes
- Total Time: 50 minutes
- Yield: 12
Ingredients
2 cups all-purpose flour
2 cups granulated sugar
3/4 cup unsweetened cocoa powder
2 teaspoons baking soda
1 teaspoon baking powder
1/2 teaspoon salt
1 cup buttermilk, room temperature
1/2 cup vegetable oil
2 large eggs, room temperature
2 teaspoons pure vanilla extract
1 cup hot water
8 ounces cream cheese, softened
1/2 cup unsalted butter, softened
4 cups powdered sugar, sifted
1 teaspoon pure vanilla extract
2 tablespoons whole milk
Instructions
Preheat the oven to 350°F (175°C). Grease and flour a 9×13 inch sheet pan.
In a large mixing bowl, sift together the flour, granulated sugar, cocoa powder, baking soda, baking powder, and salt.
In a separate bowl, whisk together the buttermilk, vegetable oil, eggs, and vanilla extract until combined.
Gradually add the wet ingredients to the dry ingredients and mix until smooth.
Slowly pour in the hot water while stirring the batter until fully combined. The batter will be thin.
Pour the batter evenly into the prepared sheet pan.
Bake for 28 to 30 minutes, or until a toothpick inserted into the center comes out clean.
Remove the cake from the oven and allow it to cool completely in the pan on a wire rack.
While the cake cools, prepare the cream cheese frosting. In a large bowl, beat the softened cream cheese and butter together until smooth and creamy.
Add the powdered sugar gradually, beating on low speed until incorporated, then increase to medium speed until smooth.
Add vanilla extract and milk, and beat until the frosting is light and fluffy.
Once the cake is completely cooled, spread the cream cheese frosting evenly over the top.
Cut into 12 squares and serve.

Classic Sheet Cake with Cream Cheese Frosting: Tips and Tricks
The Secret to That Perfectly Tender Crumb
Let’s get real—nailing the texture of a sheet cake is where a lot of pros shine or stumble. Here’s the scoop: the buttermilk isn’t just for show; it’s the acid that reacts with baking soda to give your cake that bounce and fluff without turning it into a brick. Don’t skimp on room temperature ingredients either—cold eggs or butter throw a wrench in the mix, causing uneven baking and a crumb that’s meh at best. I always mix the dry and wet ingredients separately, then combine with slow, deliberate strokes to avoid overworking the gluten—because nobody wants a cake tough like leather. And here’s a curveball: the hot water. It’s not just a random liquid add—it blooms the cocoa powder, amping up the chocolate hit and giving the batter a thinner, pourable texture that bakes into moist magic.
Ingredient Swaps That Don’t Suck
Got a dairy issue? Swap that buttermilk for an easy DIY fix: one cup of milk plus a tablespoon of white vinegar or lemon juice, let it sit for 5 minutes until it curdles—voila, instant tangy buttermilk substitute. Vegan? You can go with a flax egg (1 tablespoon flaxseed meal + 3 tablespoons water, chilled) instead of eggs, but expect a slightly denser crumb. And for the oil—if you’re out of vegetable oil, light olive oil or melted coconut oil can slide in without turning your cake into a hot mess. But steer clear of butter here; the oil keeps the crumb moist and tender where butter tends to firm up the bake more.
How to Fix a Cake Fail on the Fly
Burnt edges? Pop a serrated knife around the edges and gently slice off the scorched bits once cooled. Too dense? Next time, check your leavening agents—old baking soda or powder are the usual suspects. Or maybe you overmixed—remember, slow and steady wins the cake race. And if your frosting ends up runny or droopy? Chill it for 15–20 minutes and then try whipping it again. Sometimes cream cheese and butter don’t want to play nice if the kitchen’s too warm, so a quick chill can reset the game. If the frosting’s too thick, add a splash more milk—but do it like a boss: little by little.
Classic Sheet Cake FAQs
- Can I use regular milk instead of buttermilk?
- Yes, but it’s not a 1-to-1 swap. To mimic buttermilk’s tang, add a tablespoon of lemon juice or white vinegar to 1 cup of regular milk. Let it sit for 5 minutes before mixing.
- How do I know when the cake is done?
- Easy—stick a toothpick in the center. If it comes out clean or with just a few moist crumbs clinging, you’re golden. Undercooked cake is a buzzkill, so test near the 28-minute mark.
- Can I make the frosting ahead of time?
- Absolutely. Make the cream cheese frosting up to 2 days in advance and store it tightly covered in the fridge. Bring it back to room temp and give it a good whip before spreading to get that perfect spreadable texture.
- Is it possible to freeze the whole cake?
- Yes and no. You can freeze the baked cake layers without frosting for up to 2 months. Wrap it tightly in plastic and foil to avoid freezer burn. But freezing a frosted cake? Not recommended—the texture can get weird and the frosting might separate.
- Can I use a different pan size?
- Yes, but keep an eagle eye on baking time. A smaller pan means a thicker batter layer and longer bake—maybe 35-40 minutes. A bigger pan will cook faster. Adjust accordingly and do the toothpick test often.
