Prepare the Crust:

• In a medium bowl, combine the graham cracker crumbs and melted butter until the mixture resembles wet sand.
• Press the mixture firmly into the bottom and up the sides of a 9-inch pie dish to form the crust.
• Place the crust in the refrigerator to set while you prepare the filling.

Make the Filling:

• In a large mixing bowl, beat the softened cream cheese until smooth and creamy.
• Gradually add the sweetened condensed milk, mixing until well combined.
• Stir in the vanilla extract.
• In a separate bowl, whip the heavy whipping cream until stiff peaks form.
• Gently fold the whipped cream into the cream cheese mixture until fully incorporated.

Color and Swirl the Filling:

• Divide the filling evenly into three or more bowls, depending on how many colors you wish to use.
• Add a few drops of gel food coloring to each bowl, stirring until the desired pastel shades are achieved.
• Spoon dollops of each colored filling into the prepared crust, alternating colors randomly.
• Once all the filling is added, use a knife or skewer to gently swirl the colors together, creating a marbled effect. Be careful not to overmix.

Set the Pie:

• Refrigerate the pie for at least 4 hours, or until fully set.

Serve:

• Once set, slice and serve the pie chilled.
