The Best Moist Vanilla White Layer Cake with Cream Cheese Frosting
10 to 12 Servings
- 2 Cups All Purpose Flour
- 3 Teaspoons Baking Powder
- ½ Teaspoon Salt
- 1 Cup Unsalted Butter, room temperature plus 2 Tablespoons for the pans
- 2 Cups Granulated Sugar
- 6 Egg Whites, room temperature
- 2½ Teaspoons Pure Vanilla Extract or Vanilla Bean Paste
- ¾ Cup Sour Cream, room temperature
- ¾ Cup Half & Half, room temperature (OR mix 6 Tablespoons 2% or Whole Milk; and 6 Tablespoons Heavy Cream)
Cream Cheese Frosting
- 1 Cup Unsalted Butter, room temperature
- 4, 8 Ounce Blocks Cream Cheese, room temperature
- 3½ to 4 Cups Powdered Sugar, preferably sifted
- 2 to 3 Teaspoons Pure Vanilla Extract
Preheat oven to 350 degrees F
Make the cream cheese frosting. Set aside.
Sift the flour, baking powder, and salt. Set aside.
Using a large bowl and a hand mixer, or a stand mixer, combine and beat the butter and sugar together until it’s fluffy, about 3 minutes or so. Add the egg whites 2 at a time making sure they are well combined before adding the next addition. Stop mixing and use a spatula to scrape the bottom and sides of the bowl. Mix in the vanilla extract and sour cream. Alternately add the flour mixture with the half and half, beginning and ending with flour.
Butter and flour two 9 inch cake pans. Divide the batter evenly into each pan, about 3 cups each. Bake at 350 degrees for about 35 minutes. To ensure the cakes are done, insert a toothpick and if it comes out clean, they are done.
Allow the cakes to cool in the pan for about 5 minutes and then invert them onto a cooling rack. Allow the cakes to cool for at least an hour before frosting.
Cream Cheese Frosting
In a large bowl, mix the butter until smooth. Add the cream cheese and continue to mix until both are well combined. Add the vanilla extract. Gradually add and mix in the powdered sugar. Once the mixture is smooth it is ready to use.
Leftover frosting can be stored in an airtight container and placed in the freezer for up to 4 months.
Note: If this cake is made the day before an event place it in a COVERED AIRTIGHT cake holder and refrigerator overnight due to the frosting being made with cream cheese. Take it out of the refrigerator at least 2 hours before service so it can come down to room temperature. If it is made on the same day of service, the cake can remain at room temperature until service.
