01 - Preheat oven to 340°F. Grease a 9-inch springform pan and line the bottom with parchment paper.
02 - Layer 6 sheets of phyllo dough into the bottom of the prepared pan, brushing each sheet generously with melted butter. Combine the chopped pistachios, walnuts, granulated sugar, and cinnamon in a small bowl. Sprinkle half of this nut mixture evenly over the layered phyllo.
03 - Layer the remaining 6 phyllo sheets on top, brushing each with melted butter. Spread the remaining nut mixture over the final sheet and press down gently to compact the layers.
04 - Bake the crust for 10 minutes until lightly golden. Remove from the oven and allow to cool for about 10 minutes while preparing the filling. Maintain oven temperature at 340°F.
05 - Using an electric mixer, beat the softened cream cheese on medium speed until completely smooth and free of lumps. Add the Greek yogurt, sugar, and lemon zest, then mix until fully incorporated. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract until just combined — avoid overmixing.
06 - Pour the cheesecake filling over the cooled baklava crust. Gently tap the pan on the counter several times to release trapped air bubbles. Bake at 340°F for 45 minutes, or until the edges are set but the center still has a slight wobble when gently shaken.
07 - Turn off the oven and crack the door open slightly. Leave the cheesecake inside for 1 hour to cool gradually — this prevents cracking on the surface.
08 - Transfer the cheesecake to the refrigerator and chill for at least 3 hours, or preferably overnight, until fully set.
09 - In a small saucepan, combine the honey, water, sugar, and lemon juice over medium-low heat. Stir until the sugar dissolves completely, then bring to a gentle simmer for 3–4 minutes. Remove from heat and let the syrup cool to room temperature.
10 - Once the cheesecake is fully chilled, pour the cooled honey syrup over the top, allowing it to pool around the edges. Sprinkle with the remaining chopped pistachios. Slice with a sharp knife dipped in hot water for clean portions.
