In a bowl, beat the whipping cream and 1 tablespoon of sugar until stiff peaks form.
In a larger bowl beat together the rest of the sugar, cream cheese and vanilla extract. Once everything is well combined and the cream cheese is smooth and creamy, slowly fold in the whipping cream. Once everything is combined gently fold in the blueberries.
Pour the filling into a prepared (cooked) pie shell and chill for at least and hour to allow the pie to set up.
