Preheat your oven to 350°F (175°C) and grease and flour two round cake pans.

In a medium bowl, whisk together flour, baking powder, and salt until well combined.

In a large bowl, beat softened butter and sugar together until light and fluffy (about 3 minutes).

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

Gradually alternate adding dry ingredients and milk to the wet mixture until just combined; do not overmix.

Divide the batter evenly between prepared pans and bake for 25-30 minutes or until golden brown and a toothpick comes out clean.
