Prepare biscuits according to package directions. Cool completely.
Place a medium-sized ,metal bowl you will use to make the whipped cream into the refrigerator for fifteen minutes. This could also be the bowl of your stand mixer.
In another medium-sized bowl, combine the strawberries and granulated white sugar. Allow them to macerate for at least 15 minutes. After 15 minutes, mash about a quarter of the berries in the bowl with a potato masher and stir to mix.(You don't want to mash all the berries, just enough of them for their juices.) Let them sit while you whip the cream.
Remove the chilled bowl from the refrigerator. Use it to beat the heavy cream, confectioners' sugar, lemon juice and vanilla using a hand-held or stand mixer. Beat until stiff peaks form; about 3-5 minutes.
To assemble strawberry shortcakes, split each biscuit in half and layer with whipped cream, strawberries and biscuit top.
Garnish with a dollop of whipped cream and a spoonful of strawberries.
