Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.
In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the butter mixture, alternating with the milk. Mix until just combined.
Divide the batter evenly between the prepared cake pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cakes to cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
While the cakes are cooling, prepare the whipped cream. In a mixing bowl, beat the heavy whipping cream, powdered sugar, and vanilla extract until soft peaks form.
Once the cakes are completely cool, place one layer on a serving plate. Spread a layer of whipped cream on top and add half of the sliced strawberries.
Place the second cake layer on top and spread the remaining whipped cream over the top. Decorate with the remaining strawberries.
Chill the cake in the refrigerator for at least 30 minutes before serving to allow the flavors to meld.
