Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
In a mixing bowl, cream the softened butter and sugar until light and fluffy.
Add the eggs one at a time, beating well after each addition.
Mix in the vanilla extract.
In another bowl, whisk together the flour, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture, alternating with milk.
Mix until just combined; do not overmix.
Divide the batter evenly among the cupcake liners, filling each about 2/3 full.
Bake for 18-20 minutes or until a toothpick inserted in the center comes out clean.
Let them cool completely before frosting with whipped cream and topping with fresh berries.
