Moist Vanilla Cake with Buttercream Frosting

A soft, buttery vanilla cake with a tender crumb and rich vanilla flavor. This classic cake is easy to make and perfect for birthdays, celebrations, or everyday desserts.

Ingredients

For the Vanilla Cake

  • 2½ cups all-purpose flour
  • 1 cup unsalted butter, softened
  • 2 cups granulated sugar
  • 4 large eggs, room temperature
  • 1 tablespoon vanilla extract
  • 1 cup whole milk, room temperature
  • 1 tablespoon baking powder
  • ½ teaspoon salt

For the Vanilla Buttercream

  • 1 cup unsalted butter, softened
  • 4 cups powdered sugar
  • 2 teaspoons vanilla extract
  • 2–4 tablespoons milk or heavy cream
  • Pinch of salt

Instructions

1. Prepare the Oven and Pans

Preheat the oven to 350°F (175°C).

Grease and flour two 9-inch round cake pans. For easier removal, line the bottoms with parchment paper.

2. Cream the Butter and Sugar

Beat the softened butter and sugar together for 3–5 minutes, until light, fluffy, and pale.

This step helps incorporate air into the batter and creates a lighter cake.

3. Add the Eggs and Vanilla

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

Mix in the vanilla extract.

4. Combine the Dry Ingredients

In a separate bowl, whisk together:

  • Flour
  • Baking powder
  • Salt

5. Combine the Batter

Add the dry ingredients to the butter mixture in three additions, alternating with the milk.

Begin and end with the dry ingredients.

Mix just until combined. Do not overmix, as this can make the cake dense.

6. Bake

Divide the batter evenly between the prepared cake pans and smooth the tops.

Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.

If using two pans on the same oven rack, rotate them halfway through baking.

7. Cool

Let the cakes cool in their pans for 10 minutes.

Remove them from the pans and transfer to a wire rack. Allow them to cool completely before frosting.

Vanilla Buttercream Frosting

Instructions

  1. Beat the butter for 2–3 minutes until smooth and creamy.
  2. Gradually add the powdered sugar, mixing on low speed.
  3. Add the vanilla and salt.
  4. Add the milk or cream, one tablespoon at a time, until the frosting reaches a smooth, spreadable consistency.
  5. Beat on medium-high speed for another 2–3 minutes until light and fluffy.

Tips for a Soft, Moist Cake

  • Use room-temperature eggs, butter, and milk for a smoother batter.
  • Measure flour carefully. Too much flour can make the cake dry.
  • Cream the butter and sugar until light and fluffy.
  • Do not overmix after adding the flour.
  • Start checking the cake around 25 minutes.
  • Allow the cake to cool completely before frosting.
  • For the best texture, store the finished cake covered.
