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. Refrigerate while preparing the filling.
02 - Pour strawberry gelatin powder into a medium heat-safe bowl. Add boiling water and stir continuously for 2 minutes until completely dissolved. Incorporate cold water and mix well. Allow mixture to 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 creamy, about 2-3 minutes. Add powdered sugar and vanilla extract, continuing to mix 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 on high speed until stiff peaks form, approximately 3-5 minutes. Be careful not to over-whip.
05 - Gently fold the whipped cream into the cream cheese mixture using a rubber spatula. Add about one-third of the whipped cream at a time, using a folding motion to maintain airiness. Continue until completely smooth and fluffy, with no white streaks visible.
06 - Fold diced strawberries into the cooled gelatin mixture. Gently pour the gelatin-strawberry mixture into the creamy filling. Fold carefully just until combined, creating a marbled effect. Avoid over-mixing to prevent deflating the filling.
07 - Pour the filling into the chilled graham cracker crust. Smooth the top with an offset spatula, creating an even surface. Refrigerate uncovered for at least 4 hours, or until completely set and firm to the touch. For best results, chill overnight.
08 - Once fully set, remove pie from refrigerator. Spread whipped cream evenly over the surface or pipe decorative rosettes. Garnish with fresh sliced strawberries and optional pastel sprinkles or Easter candies. Serve immediately or return to refrigerator until ready to serve.
