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. Chill in refrigerator while preparing remaining components.
02 - Dissolve strawberry Jello powder in boiling water, stirring continuously until completely dissolved. Add 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 free of lumps. Add powdered sugar and vanilla extract, mixing until fully incorporated. In a separate chilled bowl, whip cold heavy whipping cream to stiff peaks. Gently fold whipped cream into cream cheese mixture until smooth and fluffy, taking care not to deflate the cream.
04 - Fold diced fresh strawberries into the cooled Jello mixture. Pour the Jello-strawberry mixture into the creamy filling base. Gently fold together using a spatula 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 surface with a spatula, creating an even layer. Refrigerate for at least 4 hours or until completely set and firm to the touch.
06 - Remove pie from refrigerator. Spread whipped cream evenly over the surface or pipe decorative dollops. Garnish with fresh sliced strawberries and optional pastel sprinkles or Easter candies. Slice and serve immediately.
