In a medium sized bowl, mix strawberries with 3 tablespoons sugar lemon zest and lemon juice. Toss well and refrigerate for 30 minutes.
In a large mixing bowl, whisk together the flour, ⅓ cup of sugar, baking powder, and salt.
Add the chilled butter to the bowl and use a pastry cutter or your hands to mix the butter into the flour mixture until it resembles coarse crumbs.
Add the milk and stir until a soft dough forms.
On a lightly floured surface, roll the dough out to about ½ inch thickness. Cut out 10 rounds with a biscuit cutter.
Place the rounds on a baking sheet lined with parchment paper and bake for 12-15 minutes, or until golden brown. Remove from the oven and allow them to cool.
In a separate bowl, whip the whipping cream with powdered sugar and vanilla extract until stiff peaks form.
To assemble the shortcakes, slice each biscuit in half horizontally. Place a spoonful of strawberries on the bottom half of each biscuit, followed by a dollop of whipped cream. Top with the other half of the biscuit and another spoonful of strawberries and whipped cream.
Serve immediately and enjoy!
