Filling: In a mixing bowl or the bowl of a stand mixer, beat the heavy cream for about 5 minutes until fluffy and soft peaks form. Add the cream cheese and powdered sugar and continue to beat until smooth and combined.
Strawberries: Whisk together the water and cornstarch. Heat a medium skillet to medium heat. When the skillet is hot, add the berries, sugar, and cornstarch mixture. Stir until the mixture bubbles and thickens, then turn the heat OFF. Let the berries cool slightly. Filling Pro Tip: The filling will seem a bit liquid while it is hot, but it will firm up and hold the strawberries together as it cools. Trust the process!
Assembly: Scoop the cream cheese filling into the prepared pie crust. Use a spoon or spatula to scrape some of the filling up the sides of the crust, essentially lining the crust with the cream cheese mixture.
Fill the crust/cream cheese mixture with the still-warm strawberries, mounding them up in the center of the pie.
Chill the strawberry cream cheese pie for at least 2 hours, preferably 4 hours or more. The pie will be fine uncovered in the fridge for one night; after that tent it loosely with foil or plastic wrap.
To serve, slice the pie straight from the fridge and enjoy cold or at room temp. Enjoy!
