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 gelatin powder in boiling water, stirring continuously until completely dissolved. Stir in cold water and mix well. Allow the 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 free of lumps. Add powdered sugar and vanilla extract, mixing until fully incorporated and creamy. In a separate chilled bowl, whip cold heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until smooth, fluffy, and uniform in consistency.
04 - Fold diced fresh strawberries into the cooled room-temperature gelatin mixture. Add the strawberry gelatin mixture to the creamy filling and fold gently until fully combined, taking care not to deflate the mixture. The filling should be smooth with strawberry pieces evenly distributed throughout.
05 - Pour the filling mixture into the chilled graham cracker crust. Smooth the top with a spatula, creating an even surface. Refrigerate for at least 4 hours or until completely set and firm. The pie is ready when the center no longer jiggles when gently shaken.
06 - Remove pie from refrigerator just before serving. Spread whipped cream evenly over the top or pipe decoratively. Garnish with fresh sliced strawberries and sprinkle with pastel sprinkles or Easter candies if desired. Slice into 8 wedges and serve cold.
