01 - Combine graham cracker crumbs, sugar, and melted butter in a bowl. Mix until evenly moistened and texture resembles wet sand. Press firmly into the bottom and up the sides of a 9-inch pie dish using the back of a spoon. Chill in refrigerator while preparing the filling.
02 - Place strawberry Jello powder in a medium heat-proof bowl. Pour boiling water over the gelatin and whisk continuously until completely dissolved, about 2 minutes. Stir in cold water. Allow mixture to cool to room temperature, approximately 15-20 minutes, stirring occasionally to prevent skin formation. Do not let it set.
03 - Beat softened cream cheese in a large bowl until completely smooth and creamy, about 2-3 minutes. Add powdered sugar and vanilla extract, mixing until fully incorporated and no lumps remain. Set aside.
04 - In a separate chilled bowl, whip cold heavy cream using a hand mixer or stand mixer until stiff peaks form. Be careful not to over-whip. Gently fold whipped cream into the cream cheese mixture using a rubber spatula until smooth and fluffy, taking care not to deflate the air incorporated into the cream.
05 - Stir diced fresh strawberries into the room temperature Jello mixture. Gradually add the Jello-strawberry mixture to the creamy filling, folding gently with a spatula until just combined. The mixture should have a marbled appearance.
06 - Pour the filling mixture into the chilled graham cracker crust. Smooth the top with an offset spatula. Refrigerate uncovered for at least 4 hours, or until completely set and firm to the touch. For best results, chill overnight.
07 - Before serving, spread whipped cream evenly over the set pie. Garnish with fresh sliced strawberries arranged in a decorative pattern. Add pastel sprinkles or Easter candies if desired. Slice and serve cold.
