Making Pistachio Cheesecake can be a joyful culinary adventure if you follow these straightforward steps:

1. Preheat the Oven: Preheat your oven to 325°F (160°C).
2. Prepare the Crust: In a bowl, mix the graham cracker crumbs, melted butter, and sugar. Press the mixture into the bottom of a 9-inch springform pan. Bake for 10 minutes, then remove from the oven and allow to cool.
3. Prepare the Filling: In a large mixing bowl, combine the softened cream cheese and granulated sugar. Beat until smooth and creamy.
4. Add Eggs: Add the eggs one at a time, mixing well after each addition. Ensure everything is blended well.
5. Incorporate Flavors: Mix in the vanilla extract, heavy cream, finely chopped pistachios, and pistachio pudding mix until fully integrated.
6. Pour into Crust: Pour the cheesecake filling over the cooled crust in the springform pan.
7. Bake: Place the cheesecake in the preheated oven and bake for around 50-60 minutes or until the center is set but slightly jiggly.
8. Cool: Turn off the oven and leave the cheesecake inside with the door slightly ajar for about one hour. After that, remove it and let it cool at room temperature for another hour.
9. Chill: Cover the cheesecake and refrigerate for at least 4 hours, preferably overnight.
10. Add Topping: Once chilled and firm, spread whipped cream over the top and garnish with chopped pistachios before serving.
