01 - Combine graham cracker crumbs, granulated sugar, and melted butter in a bowl. Mix until evenly moistened and all crumbs are coated. Press firmly into the bottom and up the sides of a 9-inch pie dish, creating an even layer. Place in refrigerator to chill while preparing the filling.
02 - Dissolve strawberry Jello powder in boiling water, stirring until completely dissolved. Stir in cold water. Let mixture cool to room temperature, approximately 15-20 minutes, ensuring it remains liquid and does not begin to set.
03 - Beat softened cream cheese in a large bowl until completely smooth and no lumps remain. Add powdered sugar and vanilla extract, mixing until fully incorporated and smooth. In a separate chilled bowl, whip cold heavy cream to stiff peaks. Gently fold whipped cream into the cream cheese mixture until smooth and fluffy, being careful not to deflate the mixture.
04 - Stir diced fresh strawberries into the cooled room-temperature Jello mixture. Pour the Jello mixture into the creamy filling base and fold gently until just combined, creating a marbled effect. Do not overmix.
05 - Pour the combined filling mixture into the chilled graham cracker crust. Smooth the top with an offset spatula. Refrigerate for at least 4 hours or until completely set and firm to the touch. For best results, chill overnight.
06 - Remove pie from refrigerator just before serving. Spread or pipe whipped cream over the top of the set pie. Garnish with fresh sliced strawberries and optional pastel sprinkles or Easter candies. Slice into 8 wedges and serve cold.
