Preheat oven to 450℉. Gather the ingredients so that you have everything close at hand on the counter or table. Spray a round or square baking sheet with baking spray.
Prepare the Strawberries
Wash and drain 6 cups fresh strawberries. Using a pairing knife, remove the tops from the strawberries.
In a serving bowl, mix together the sliced strawberries and 1/3 cup granulated sugar. If desired, mash with a fork or potato masher. Cover and refrigerate until ready to serve.
Prepare the Shortcake
In a medium bowl, sift together 2 cups all-purpose flour, 2 tablespoons granulated sugar, 5 tablespoons granulated sugar and 1/2 teaspoon salt.
Cut in 1/2 cup butter with a blending fork until it resembles coarse crumbs. Add 1 large egg (beaten), and 2/3 cups whole milk. Mix just to combine.
Spread the dough to the edges of the prepared cake pan. Sprinkle with remaining 2-3 tablespoons granulated sugar.
Bake in preheated oven for 12-15 minutes until golden brown. Serve warm with strawberries and Whipped Cream. Serves 8.
