01 - Preheat your oven to 350°F. In a medium bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Press the mixture firmly and evenly into the bottom and up the sides of a 9-inch pie dish.
02 - Bake the crust for 10-12 minutes until lightly golden and set. Remove from oven and allow to cool completely on a wire rack before filling.
03 - In a large mixing bowl, beat the cream cheese, mascarpone, powdered sugar, and vanilla extract with an electric mixer until completely smooth and creamy, about 2-3 minutes. Scrape down the sides of the bowl as needed.
04 - In a separate chilled bowl, whip the heavy cream with a hand mixer or stand mixer until soft peaks form. Be careful not to overwhip.
05 - Gently fold the whipped cream into the cheese mixture using a spatula, being careful to maintain the light and airy texture. Mix until just combined and no streaks remain.
06 - Divide the filling evenly among 3-4 small bowls. Add a few drops of different gel food coloring to each bowl and fold gently until pastel shades are achieved. Start with a small amount—you can always add more color.
07 - Spoon dollops of each colored filling randomly over the cooled crust, alternating colors. Use a skewer, knife, or toothpick to gently swirl the colors together in a marble pattern. Work lightly and avoid overmixing to preserve the distinct swirls.
08 - Smooth the top lightly with a spatula. Cover the pie dish with plastic wrap and refrigerate for at least 2 hours, or until completely set and firm. For best results, chill overnight.
09 - Before serving, garnish the pie with pastel sprinkles or mini chocolate eggs if desired. Slice with a sharp knife dipped in warm water for clean cuts. Serve chilled.
