Preheat your oven to 350°F (175°C) and grease your cake pans.
In a large mixing bowl, cream the softened butter and sugar until light and fluffy.
Add eggs one at a time, mixing well after each addition.
Stir in the vanilla extract.
In a separate bowl, combine flour, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture, alternating with milk.
Mix until just combined; do not overmix.
Pour the batter evenly into the prepared pans.
Bake for 25 minutes or until a toothpick inserted comes out clean.
Allow cakes to cool completely before decorating with frosting and Easter candies.
