Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

In a mixing bowl, whisk together the flour, sugar, baking powder, and salt until well combined.

In another bowl, cream the softened butter until smooth. Gradually add the sugar and beat until light and fluffy.

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

Gradually add the dry ingredients to the butter mixture, alternating with the milk. Mix until just combined.

Divide the batter evenly between the prepared pans. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

Allow the cakes to cool in the pans for 10 minutes, then transfer to wire racks to cool completely before frosting.
