1-Preheat oven: to 325°F (163°C). Grease and flour a 9-inch springform pan and line the bottom with parchment paper to ensure easy removal later.

2-Combine crust ingredients: In a medium bowl, combine 2¼ cups graham cracker crumbs, ¼ cup brown sugar, and ½ cup melted butter. Press the mixture into the bottom and sides of the prepared pan using a flat-bottomed glass for even pressing, creating a sturdy base.

3-Bake crust: Bake the crust for 10 minutes, then remove it from the oven and let it cool while you prepare the filling.

4-Cream cheese mixture: Using a stand mixer with the paddle attachment, cream together 32 oz. cream cheese, 1 cup sugar, and 2 tablespoons all-purpose flour until smooth, which takes about 3 minutes on medium speed.

5-Add eggs: Whisk 4 large eggs and 2 large egg yolks together, then add them to the cream cheese mixture in two additions, mixing fully after each to avoid lumps.

6-Add sour cream, vanilla, and passionfruit: Add ¼ cup sour cream, ½ tablespoon vanilla extract, and ½ cup passionfruit pulp; mix until well combined, scraping the bowl sides and bottom with a spatula as needed for a uniform batter.

7-Pour batter: Pour the batter over the cooled crust in the pan.

8-Prepare water bath: Wrap the bottom of the pan with aluminum foil. Place the pan in a larger baking or roasting pan and add ½ to ¾ inch of water to create a water bath that helps the cheesecake bake evenly.

9-Bake cheesecake: Bake for 80 to 90 minutes until the center is just barely set with a slight jiggle in the middle.

10-Make passionfruit topping: For the passionfruit topping, whisk 1 tablespoon cornstarch with 1 tablespoon water until smooth. Stir in 1 cup passionfruit pulp and cook over medium heat until it boils and thickens, about 30 seconds.

11-Spread topping: Spread the topping over the baked cheesecake using an offset spatula for a neat finish.

12-Refrigerate and serve: Refrigerate for at least 4 hours before removing the springform pan and slicing. Optionally, decorate with fresh whipped cream before serving to add a special touch.
