Preheat the oven to 350°F and line a 8 inch round pan with parchment paper on the bottom and either spray the sides with cooking spray or butter and flour them. Set aside.
In a large mixing bowl combine the flour, baking powder, sugar, and salt and mix to combine.
Cut the cold butter into small pieces and use a pastry cutter or your fingers to cut the butter into the dry ingredients until the mixture starts to clump together.
Make a well in the center and add the milk and vanilla extract. Mix until just combined.
Transfer the batter to your prepared pan, using a rubber spatula to spread the batter into an even layer. If desired, top with coarse sugar (I highly recommend).
Bake for 35 minutes or until a knife inserted into the middle comes out mostly clean. Transfer the cake to a wire rack to cool for 15 minutes before running a butter knife along the edge of the cake and turning it out of the pan. Allow to cool completely before topping.
While the cake cools, make the whipped cream and prep the strawberries. Place the sliced strawberries in a medium sized bowl with the sugar and stir to combine. Cover and set aside.
Beat the heavy cream in a stand mixer fitted with the whisk attachment until soft peaks form and the whipped cream holds its shape.
When ready to serve, spoon the whipped cream over the top of the cake and top with strawberries!
