Ingredients

For the Cake

  • 2 1/2 cups all-purpose flour
  • 2 1/2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 1/2 cups granulated sugar
  • 1 cup unsalted butter (room temperature)
  • 4 large eggs (room temperature)
  • 1 cup whole milk (room temperature)
  • 2 teaspoons vanilla extract

For the Frosting

  • 1 cup unsalted butter (room temperature)
  • 4 cups powdered sugar
  • 1/4 cup whole milk
  • 2 teaspoons vanilla extract

Ingredient Tips & Swaps

  • Butter: Room temperature butter ensures smooth blending. Salted butter can be used—just reduce added salt.

  • Flavor: Add 1/2 tsp almond extract to the batter for a bakery-style twist.

How to Make Classic Vanilla Sheet Cake

1. Prep the Oven & Pan

Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch pan or line with parchment.

2. Combine Dry Ingredients

Whisk together flour, baking powder, baking soda, and salt. Set aside.

3. Cream Butter and Sugar

In a large bowl, beat butter and sugar for 3–5 minutes until light and fluffy.

4. Add Eggs and Vanilla

Add eggs one at a time, beating well. Stir in vanilla extract.

5. Mix in Dry Ingredients

Alternate adding dry ingredients and milk to the butter mixture, starting and ending with flour. Mix until just combined.

6. Bake

Pour into the prepared pan and smooth the top. Bake 25–30 minutes until a toothpick comes out clean.

7. Cool

Let the cake cool in the pan for 10 minutes, then transfer to a rack to cool fully.


Make the Vanilla Frosting

  1. Beat the butter on medium speed until creamy.
  2. Add powdered sugar gradually, beating on low at first.
  3. Add milk and vanilla, then beat until light and fluffy.
  4. Frost the cooled cake and spread evenly with a spatula.

Tips for Success

  • Room Temperature Ingredients: This ensures smooth mixing and an even crumb.
  • Don’t Overmix: Mix just until the batter is combined for the most tender texture.
