Vanilla Sheet Cake in Steps
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures the cake bakes evenly and rises beautifully.
Step 2: Prepare the Baking Pan
Grease a 9×13 inch baking sheet with butter or non-stick spray, and line the bottom with parchment paper for easy removal.
Step 3: Mix Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, baking powder, and kosher salt until combined.
Step 4: Cream the Butter and Sugar
In a separate bowl, beat the room temperature unsalted butter and granulated sugar together until light and fluffy, about 3-4 minutes.
Step 5: Add the Oil and Eggs
Beat in the vegetable oil until well incorporated. Then, add the eggs one at a time, mixing well after each addition. Stir in the pure vanilla extract.
Step 6: Alternate Dry Ingredients and Milk
Gradually add the flour mixture to the butter mixture, alternating with the milk. Start and end with the flour, mixing until just combined. Do not overmix!
Step 7: Bake the Cake
Pour the batter into the prepared baking sheet and spread it out evenly. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Step 8: Cool the Cake
Once baked, remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer it to a cooling rack to cool completely.
Step 9: Make the Frosting
In a large bowl, beat the slightly melted unsalted butter until creamy. Gradually add the powdered sugar, mixing on low until combined. Add the heavy cream and vanilla extract, then beat on high for 2-3 minutes until fluffy.
Step 10: Frost the Cake
Once the cake is completely cooled, spread the frosting evenly over the top. You can use a spatula to create swirls or keep it smooth.
Smart Substitutions
- Gluten-Free Flour: Use a 1:1 gluten-free flour blend in place of all-purpose flour.
- Plant-Based Butter: Substitute for unsalted butter to make it dairy-free.
- Almond Milk: Use in place of regular milk for a nutty flavor.
- Agave Syrup: Replace granulated sugar with agave for a lower glycemic index.
Flavor Logic
The combination of butter and sugar creates a rich base that enhances the vanilla flavor. The addition of oil ensures moisture, while the eggs provide structure and stability. The balance of dry and wet ingredients creates a tender crumb, making each bite melt in your mouth. The frosting, with its creamy texture and additional vanilla, complements the cake perfectly, making every slice a delightful experience.
Keep-It-Fresh Plan
To keep your Vanilla Sheet Cake fresh, store it in an airtight container at room temperature for up to 3 days. If you need to keep it longer, refrigerate it for up to a week, but be sure to bring it back to room temperature before serving for the best texture. You can also freeze the cake—just slice it and wrap each piece tightly in plastic wrap, then place in a freezer-safe bag. It will stay good for up to 3 months.
Popular Questions
Can I use cake flour instead of all-purpose flour?
Yes, you can use cake flour for an even lighter texture. Just remember to adjust the amount slightly, as cake flour is lighter than all-purpose flour.
How can I make this cake chocolate-flavored?
To make a chocolate version, replace ½ cup of the all-purpose flour with unsweetened cocoa powder. This will give you a rich chocolate flavor without compromising texture.
Can I make this cake ahead of time?
Absolutely! You can bake the cake a day in advance. Just wrap it in plastic wrap once cooled to prevent it from drying out.
What can I use instead of heavy cream in the frosting?
You can substitute heavy cream with milk or a dairy-free alternative, although the texture may be slightly less creamy.
