Ingredients
Here’s what you’ll need to create this delectable vanilla sheet cake:
- For the Cake:
- 3 cups all-purpose flour
- 2 cups granulated sugar
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 ½ cups buttermilk (or see substitution below)
- ½ cup vegetable oil
- 2 large eggs
- 2 teaspoons vanilla extract
- 1 cup boiling water
- For the Frosting:
- ½ cup (1 stick) unsalted butter, softened
- 4 cups powdered sugar
- ¼ cup milk (or more, to desired consistency)
- 2 teaspoons vanilla extract
- Pinch of salt

Instructions
Follow these simple steps to bake the perfect vanilla sheet cake:
- Preheat and Prep: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. Alternatively, you can line the pan with parchment paper, leaving an overhang for easy removal.
- Combine Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
- Add Wet Ingredients: Add the buttermilk, oil, eggs, and vanilla extract to the dry ingredients. Beat with an electric mixer on medium speed for about 2 minutes, or until well combined. The batter will be slightly lumpy, and that’s okay.
- Add Boiling Water: Gradually pour in the boiling water while mixing on low speed. The batter will become very thin. Don’t worry, this is normal!
- Pour and Bake: Pour the batter into the prepared baking pan and spread evenly. Bake for 25-30 minutes, or until a wooden skewer inserted into the center comes out clean.
- Cool Completely: Let the cake cool in the pan for 10-15 minutes before inverting it onto a wire rack to cool completely. Make sure the cake is completely cool before frosting.
- Make the Frosting: While the cake is cooling, prepare the frosting. In a large bowl, beat the softened butter with an electric mixer until light and fluffy.
- Add Powdered Sugar: Gradually add the powdered sugar, one cup at a time, beating well after each addition.
- Add Milk and Vanilla: Add the milk and vanilla extract and beat until smooth and creamy. Add more milk, one tablespoon at a time, if needed to reach your desired consistency. Add a pinch of salt to balance the sweetness.
- Frost the Cake: Once the cake is completely cool, frost it evenly with the vanilla frosting.
- Decorate (Optional): Decorate with sprinkles, fresh berries, chocolate shavings, or any other toppings you desire.
- Serve and Enjoy! Slice and serve your delicious vanilla sheet cake.
Tips for Success
Here are some helpful tips to ensure your vanilla sheet cake is a masterpiece:
- Don’t Overmix: Overmixing the batter can lead to a tough cake. Mix until just combined.
- Measure Accurately: Accurate measurements are crucial for baking. Use measuring cups and spoons designed for baking.
- Room Temperature Ingredients: While the eggs and buttermilk don’t *have* to be room temperature, it helps them incorporate more easily into the batter, resulting in a smoother texture.
- Buttermilk Substitute: If you don’t have buttermilk, you can make a quick substitute by adding 1 ½ tablespoons of lemon juice or white vinegar to a liquid measuring cup. Fill the cup with milk until it reaches the 1 ½ cup mark. Let it sit for 5 minutes to curdle slightly before using.
- Check for Doneness: Use a wooden skewer or toothpick to check for doneness. Insert it into the center of the cake; if it comes out clean or with a few moist crumbs, the cake is done.
- Cool Completely: Ensure the cake is completely cool before frosting to prevent the frosting from melting.
- Customize the Flavor: Feel free to add a touch of almond extract or lemon zest to the cake batter or frosting for a different flavor profile.
Storage Instructions
To keep your vanilla sheet cake fresh and delicious:
- Room Temperature: Store the frosted cake in an airtight container at room temperature for up to 3 days.
- Refrigerator: For longer storage, store the frosted cake in an airtight container in the refrigerator for up to 5 days. Let it come to room temperature for about 30 minutes before serving for the best flavor and texture.
- Freezer: You can also freeze the cake, either frosted or unfrosted. Wrap it tightly in plastic wrap and then in aluminum foil. Frozen cake will keep for up to 2-3 months. Thaw overnight in the refrigerator before serving.

FAQ
Here are some frequently asked questions about this vanilla sheet cake recipe:
- Can I use a different type of flour? While all-purpose flour is recommended for the best results, you can use cake flour for an even more tender crumb.
- Can I use butter instead of oil? Yes, you can substitute melted butter for the oil. However, the cake may not be as moist.
- Can I use a different size pan? A 9×13 inch pan is ideal for this recipe. If you use a smaller pan, the cake will be thicker and may require a longer baking time.
