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 Vanilla Frosting

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

 Instructions

Preheat your oven to 350°F (175°C). Grease and flour a 9x13-inch baking pan or line it with parchment paper.

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

In a large bowl, beat the butter and sugar together until light and fluffy, about 3-5 minutes.

Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.

Gradually add the dry ingredients to the butter mixture, alternating with the milk. Begin and end with the dry ingredients, mixing until just combined. Be careful not to overmix.

Pour the batter into the prepared baking pan and smooth the top.

Bake for 25-30 minutes, or until a toothpick inserted into the center of the cake comes out clean.

Allow the cake to cool in the pan for 10 minutes, then remove it from the pan and transfer to a wire rack to cool completely.

For the frosting, beat the butter on medium speed until creamy. Gradually add the powdered sugar, one cup at a time, beating on low speed until incorporated. Then, increase the speed to medium and beat until smooth.

Add the milk and vanilla extract, and continue beating until the frosting is light and fluffy.

Spread the frosting evenly over the cooled cake.
