01 - Preheat oven to 340°F. Grease a 9-inch springform pan and line the base with parchment paper.
02 - Combine crushed biscuits, melted butter, and honey in a bowl until the mixture resembles wet sand. Press firmly and evenly into the bottom of the prepared pan. Bake for 10 minutes, then set aside to cool slightly.
03 - In a large bowl, beat cream cheese and sugar together until completely smooth. Add yogurt, vanilla extract, and lemon juice, mixing until well combined. Beat in the eggs one at a time on low speed, mixing just until each is incorporated. Gently fold in the roughly chopped pistachios.
04 - Lay one sheet of phyllo dough over the cooled crust and brush with melted butter. Sprinkle evenly with a mixture of finely chopped pistachios, walnuts, and cinnamon. Repeat with 4 to 5 layers, finishing with a butter-brushed sheet of phyllo on top.
05 - Pour the cheesecake batter over the baklava layer, spreading it into an even surface. Bake for 50 to 55 minutes, until the center is just set with a slight wobble remaining. Turn off the oven, crack the door open slightly, and allow the cake to cool inside for 1 hour.
06 - While the cheesecake cools, combine water and sugar in a small saucepan over medium heat, stirring until the sugar fully dissolves. Stir in honey, lemon juice, and orange blossom water, then simmer for 5 more minutes. Remove from heat and let cool to room temperature.
07 - Transfer the cooled cheesecake to the refrigerator and chill for at least 4 hours, preferably overnight, until fully set.
08 - Drizzle the cooled syrup generously over the cheesecake and scatter chopped pistachios across the top. Slice into 12 portions and serve.
