01 - Preheat oven to 350°F. In a medium bowl, combine crushed graham crackers, melted butter, and granulated sugar. Press firmly into the bottom and sides of a 9-inch pie dish, creating an even layer.
02 - Bake the crust for 10-12 minutes until lightly golden. Remove from oven and let cool completely while preparing the filling.
03 - In a large bowl, beat cream cheese, mascarpone, powdered sugar, and vanilla extract with an electric mixer until smooth and creamy, about 2 minutes.
04 - In a separate bowl, whip heavy cream to soft peaks using an electric mixer. Gently fold the whipped cream into the cheese mixture until fully incorporated and no white streaks remain.
05 - Divide the filling evenly into 3-4 small bowls. Add a small drop of different gel food coloring to each bowl and mix gently until pastel shades are achieved.
06 - Spoon dollops of each colored filling randomly onto the cooled crust. Using a skewer or butter knife, gently swirl the colors together in a circular motion to create a marbled effect. Be careful not to overmix.
07 - Smooth the top lightly with an offset spatula. Cover loosely with plastic wrap and refrigerate for at least 2 hours or until completely set, preferably overnight for best results.
08 - Remove from refrigerator and decorate with pastel sprinkles or mini chocolate eggs just before serving. Slice and serve chilled.
