Toss the strawberries with the confectioners' sugar, liqueur, juices, and zest. Allow to marinate refrigerated for 30 minutes. Split the vanilla bean open with a knife and scrape out the seeds. Add the seeds to the whipping cream in an ice cold bowl and whip the cream to soft peaks just prior to serving. Serve one scoop of ice cream in a martini glass, spoon some marinated strawberries over the ice cream and serve with a dollop of whipped cream on top.
