Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans.
In a large bowl, cream together the butter and sugar until light and fluffy.
Add eggs one at a time, beating well after each addition.
Stir in the vanilla extract.
In another bowl, combine flour, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture, alternating with milk.
Mix until just combined, being careful not to overmix.
Divide the batter evenly between the prepared pans.
Bake for 25-30 minutes, or until a toothpick inserted comes out clean.
Let the cakes cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
Whip the cream with powdered sugar until soft peaks form, then layer the cakes with cream and strawberries.
