Preheat oven to 350 degrees. Prebake the crust for 6 minutes or until it just starts to turn golden brown (this makes the crust more resilient to filling). Let the crust cool, and mix together remaining ingredients. Fill pie crust and bake for 20-22 minutes. As soon as the top turns the slightest bit brown, remove from oven and cool in fridge. Top with whipped cream.
