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

In a medium bowl, whisk together the flour, baking powder, and salt; set aside.

In a large bowl, cream the softened butter and sugar until fluffy. Add the eggs one at a time, followed by the vanilla extract.

Gradually mix in the dry ingredients alternately with the milk until just combined. Gently fold in the sliced strawberries.

Divide the batter between prepared pans and bake for 25-30 minutes or until a toothpick comes out clean. Let cool completely before frosting.
