Preheat your oven to 350°F (175°C).

Grease and flour two heart-shaped cake pans.

Cream the butter and sugar together in a bowl until light and fluffy.

Incorporate eggs one at a time, mixing well after each addition.

Blend in the vanilla extract.

Combine flour, baking powder, and salt in another bowl.

Alternately add the dry ingredient mixture and milk to the wet mixture.

Pour the batter into the prepared pans, filling each about 2/3 full.

Bake for 25-30 minutes or until a toothpick comes out clean.

Cool the cakes in the pans for about 10 minutes before transferring them to a wire rack.
