• 1/2 teaspoon salt
• 1 cup unsalted butter, softened
• 1 3/4 cups granulated sugar

• 1/2 cup sour cream

How to Make Fluffy Vanilla Sheet Cake

Step 1: Prepare the Baking Pan

Preheat your oven to 350°F (175°C).

Grease a 9×13-inch baking pan and lightly dust it with flour or line it with parchment paper for easier removal.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.

Set the dry mixture aside.

Step 3: Cream the Butter and Sugar

In a large mixing bowl, beat the softened butter and granulated sugar together until light and fluffy. This usually takes about 3 to 4 minutes using an electric mixer.

Creaming the butter properly helps create the cake’s soft and airy texture.

Step 4: Add the Eggs and Vanilla

Add the eggs one at a time, mixing well after each addition.

Stir in the vanilla extract and vegetable oil.

Step 5: Combine the Wet and Dry Ingredients

Add the dry ingredients gradually, alternating with the milk and sour cream.

Mix until just combined. Be careful not to overmix the batter because this can make the cake dense instead of fluffy.

Step 6: Bake the Cake

Pour the batter evenly into the prepared baking pan.

Bake for approximately 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.

The top should be lightly golden and spring back gently when touched.

Step 7: Cool Completely

Allow the cake to cool completely before frosting. If the cake is still warm, the frosting may melt.

How to Make Vanilla Buttercream Frosting

In a large bowl, beat the softened butter until creamy and smooth.

Gradually add the powdered sugar, mixing slowly at first to avoid spills.

Add the vanilla extract, salt, and milk or cream until the frosting reaches a smooth and fluffy consistency.

Spread the frosting evenly over the cooled cake using a spatula.

Tips for the Best Vanilla Sheet Cake

For the fluffiest texture, use room-temperature ingredients. Cold eggs or milk can affect how evenly the batter mixes.

Do not overbake the cake. Checking it a few minutes early helps prevent dryness.

Using both butter and oil gives the cake the perfect combination of flavor and moisture.

Pure vanilla extract provides the best flavor compared to artificial vanilla flavoring.

Delicious Variations

One of the best things about vanilla sheet cake is how easy it is to customize.

Chocolate Vanilla Marble Cake

Swirl melted chocolate or cocoa batter into the vanilla batter before baking.

Funfetti Cake

Add colorful sprinkles directly into the batter for a fun birthday-style cake.

Lemon Vanilla Cake

Mix lemon zest into the batter for a bright citrus flavor.

Strawberry Vanilla Cake

Top the frosted cake with fresh strawberries or strawberry glaze.

How to Store Vanilla Sheet Cake

Store the cake covered at room temperature for up to 3 days.

For longer storage, refrigerate it for up to 5 days. Allow refrigerated cake to come to room temperature before serving for the best texture.

You can also freeze unfrosted cake for up to 2 months.
