01 - Preheat oven to 350°F. In a bowl, combine crushed biscuits, melted butter, and sugar. Press firmly into the bottom and sides of a 9-inch pie dish.
02 - Bake crust for 10-12 minutes until lightly golden. Let cool completely on a wire rack before filling.
03 - In a large bowl, beat cream cheese, mascarpone, powdered sugar, and vanilla extract until smooth and creamy, about 2-3 minutes.
04 - In a separate chilled bowl, whip heavy cream to soft peaks using an electric mixer. Fold gently into the cheese mixture until fully incorporated.
05 - Divide the filling evenly into 3-4 small bowls. Tint each with a drop of different gel food coloring 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. Do not overmix to preserve distinct patterns.
07 - Smooth the top lightly, cover with plastic wrap, and refrigerate for at least 2 hours or until completely set and firm.
08 - Before serving, decorate with pastel sprinkles or mini chocolate eggs if desired. Slice and serve chilled.
