Step 1: Prepare the crust. In a medium bowl, combine the crushed graham crackers, melted butter, and sugar. Mix until well combined.
Step 2: Press the crust. Press the mixture firmly into the bottom of a 9-inch pie plate. You can use the back of a spoon or your fingers. Place in the refrigerator to chill while you prepare the filling.
Step 3: Beat cream cheese. In a large mixing bowl, beat the softened cream cheese until smooth and creamy.
Step 4: Add sweetness and flavor. Gradually beat in the powdered sugar until fully incorporated and smooth. Stir in the vanilla extract. If desired, add green food coloring at this stage, a few drops at a time, until you reach your desired Grinch-y green hue.
Step 5: Whip the cream. In a separate cold bowl, whip the cold heavy whipping cream until stiff peaks form.
Step 6: Combine filling. Gently fold the whipped cream into the cream cheese mixture until no streaks remain. Be careful not to overmix, as this can deflate the whipped cream.
Step 7: Assemble the pie. Spoon the cream cheese filling into the chilled graham cracker crust, spreading it evenly.
Step 8: Chill the pie. Refrigerate the pie for at least 4 hours, or preferably overnight, until it is firmly set.
Step 9: Serve and enjoy! Once set, slice and serve your delightful No-Bake Grinch Cream Cheese Pie. Garnish with a single red heart candy or whipped cream if desired.
