Preheat the oven to 350°F. Butter and flour 3  inch round cake pans or spray with baking spray. [i.e. Bakers Joy]
Sift together the all-purpose flour, baking powder, salt and baking soda. Set aside.
In a large mixing bowl using a mixer, cream together the softened butter, granulated sugar and vanilla extract. Beat for around 3-4 minutes.
Add the eggs one at a time beating well after each addition. Stop and scrape the sides of the bowl periodically so all ingredients will combine.
Add the sifted dry ingredients alternately with the buttermilk. Beat on medium speed until all has been added, then increase the speed of the mixer and beat for 1-2 minutes
Divide evenly between the prepared pans. Bounce the pans on the counter a couple of times to release trapped air.
Place into the oven and bake for 25 minutes or until a toothpick inserted into the center comes back clean. Cool completely in the pans on a baking rack.
Place strawberries in a bowl and sprinkle with sugar. Set aside while you prepare the filling.
To prepare the filling: In a medium size mixing bowl cream together the cream cheese, sugar and vanilla. Add the cream. Beat on medium-high for 3-5 minutes or until stiff peaks form.
To assemble: Center one cake layer on stand. Top with 1/2 of sliced strawberries and 1/3 whipped cream. Repeat ending with whipped cream. Garnish with whole berries cut in half, if desired.
Chill thoroughly for at least 4 hours before serving. Store leftovers chilled.
