In a bowl, mix all ingredients and press into a 8-9 inch pie dish. Bake for 7 minutes, and allow to cool for 15 minutes.
Filling
In a large bowl, beat the cream cheese, powdered sugar, and vanilla until light and fluffy.
In separate bowl, beat the heavy whipping cream until whipped cream. Fold into the cream cheese mixture.
Raspberry Sauce
In a small saucepan, combine sugar and cornstarch. Stir in the water and 1 1/2 cups raspberries. Bring to a boil for 2 minutes or until thickened; stirring constantly.
Pour into a bowl and refrigerate until chilled.
Assembly
Spread the cream cheese filling into your crust (creating a bowl effect if needed to help keep sauce from over flowing). Pour sauce on top of the filling.
Garnish the top with the remaining 1 cup of raspberries. Refrigerate leftovers.
