Preheat the oven to 350°F (175°C).
Prepare a 9-inch springform pan by greasing it lightly.
Mix the crushed nuts with melted butter and sugar.
Press the nut mixture firmly into the bottom of the springform pan.
In a large bowl, beat the softened cream cheese until smooth.
Add the sugar, sour cream, eggs, vanilla, and cinnamon to the cream cheese, mixing until combined.
Pour the cheesecake mixture over the nut crust in the pan.
Bake in the preheated oven for 45–50 minutes until the edges are set but the center slightly jiggles.
Remove the cheesecake from the oven and let it cool at room temperature for at least 1 hour before refrigerating.
While cooling, prepare the honey syrup by simmering honey with water in a small saucepan.
After chilling for at least 4 hours, drizzle the honey syrup over the cheesecake.
Slice and serve chilled, garnished with additional crushed nuts if desired.
