Place softened cream cheese in a mixing bowl. Beat until smooth and creamy. Add powdered sugar and mix again. Make sure there are no lumps for a soft filling texture.

Pour in peppermint extract and mix well. Add green food coloring slowly. Stir until you get a light green shade. Do not add too much color at once.

In another bowl, whip the heavy cream until soft peaks form. Use an electric mixer for best results. The cream should be fluffy and hold its shape well.

Gently fold the whipped cream into the cream cheese mixture. Mix slowly to keep it light. Add whipped topping and fold again until everything looks smooth and airy.

Stir in crushed chocolate cookies or chocolate chips. Mix gently so they spread evenly. This adds a nice crunch and chocolate flavor to the pie filling.

Pour the prepared filling into the graham cracker crust. Use a spatula to spread it evenly. Smooth the top so it looks neat and ready for chilling.

Place the pie in the refrigerator for at least 4 hours. This helps it set properly. The filling should become firm but still creamy when ready to serve.

Before serving, add whipped cream on top. Garnish with cherries and extra chocolate pieces. Slice and serve cold. Enjoy your delicious No Bake Shamrock Shake Pie Recipe.
