Preheat the oven to 350°F (175°C).

Grease and flour your two 9-inch round cake pans.

In a mixing bowl, whisk together the flour, baking powder, and salt.

In another bowl, beat the softened butter and sugar until light and fluffy.

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

Gradually add the dry ingredients to the butter mixture, alternating with the milk.

Evenly divide the batter between the prepared cake pans.

Bake in the preheated oven for 25-30 minutes or until a toothpick inserted in the center comes out clean.

Let the cakes cool in the pans for about 10 minutes before transferring them to a cooling rack.
