01 - Combine graham cracker crumbs, sugar, and melted butter in a bowl. Mix until evenly moistened and crumbs hold together when pressed. Press mixture firmly into the bottom and up the sides of a 9-inch pie dish, creating an even layer. Chill in refrigerator while preparing filling.
02 - Add strawberry Jello powder to boiling water in a medium bowl. Stir continuously until completely dissolved, approximately 2 minutes. Mix in cold water. Allow mixture to cool to room temperature, about 15-20 minutes, ensuring it remains liquid and does not begin setting.
03 - Beat softened cream cheese in a large bowl until completely smooth, approximately 2-3 minutes. Add powdered sugar and vanilla extract, mixing until well incorporated and no lumps remain. Set aside.
04 - In a separate chilled bowl, whip cold heavy cream using hand or stand mixer until stiff peaks form, approximately 3-5 minutes. Peaks should stand straight when beaters are lifted.
05 - Gently fold whipped cream into cream cheese mixture using a spatula, incorporating until smooth and fluffy. Add diced strawberries to cooled Jello mixture. Fold Jello-strawberry mixture into creamy filling until just combined with streaks remaining.
06 - Pour filling into chilled crust. Smooth top with spatula, creating an even surface. Refrigerate uncovered for at least 4 hours or until completely set and firm to the touch.
07 - Top chilled pie with whipped cream, spreading evenly or piping decorative border. Arrange sliced fresh strawberries on top. Add pastel sprinkles or Easter candies if desired. Serve cold.
