01 - Preheat oven to 350°F. Combine crushed biscuits, melted butter, and sugar in a bowl. Press firmly into the bottom and sides of a 9-inch pie dish.
02 - Bake the crust for 10-12 minutes until lightly golden. Allow to cool completely before filling.
03 - Beat cream cheese, mascarpone, powdered sugar, and vanilla extract in a large bowl until completely smooth and creamy.
04 - In a separate bowl, whip heavy cream to soft peaks. Gently fold the whipped cream into the cheese mixture until fully incorporated.
05 - Divide the filling evenly into 3-4 small bowls. Add a drop of different gel food coloring to each bowl and mix until pastel shades are achieved.
06 - Spoon dollops of each colored filling randomly onto the cooled crust. Using a skewer or knife, gently swirl the colors together for a marbled effect. Be careful not to overmix.
07 - Smooth the top lightly, cover with plastic wrap, and refrigerate for at least 2 hours or until completely set.
08 - Before serving, decorate the top with pastel sprinkles or mini chocolate eggs if desired. Slice and serve chilled.
