Preheat your oven to 325°F (163°C).
In a mixing bowl, combine the melted butter, chopped pistachios, and sugar. Layer 5 sheets of phyllo pastry in the bottom of a 9-inch springform pan, brushing each layer with the butter mixture. Once you've added 5 layers, sprinkle half of the nut mixture over the crust.
Add the remaining 5 sheets of phyllo, again brushing each layer with the butter mixture. Sprinkle the remaining nut mixture on top, and brush another layer of melted butter over everything. Bake in the preheated oven for 10-15 minutes, until golden, then remove and set aside.
In a large bowl, beat the cream cheese and sugar until smooth using an electric mixer. Add the honey, eggs, vanilla, Greek yogurt, and ground cinnamon, mixing until fully combined and creamy.
Pour the filling over the baked phyllo crust, smoothing the top with a rubber spatula. Bake for 45-50 minutes or until the center is set and a slight jiggle remains.
While the cheesecake is baking, prepare the topping by gently warming the honey in a saucepan until it’s easy to drizzle.
Once the cheesecake is finished baking, let it cool at room temperature for about 30 minutes. Then, drizzle the warm honey over the top and sprinkle with toasted pistachios for added crunch.
Refrigerate the cheesecake for at least 4 hours or overnight for the best flavor and texture.
Before serving, slice the cheesecake and enjoy!
