01 - Preheat oven to 350°F. Grease a 9x9-inch baking dish. In a bowl, combine flour, melted butter, pecans, sugar, and salt. Press mixture into the bottom of the prepared dish.
02 - Bake crust for 18–20 minutes until lightly golden. Allow to cool completely before proceeding with the filling.
03 - Beat cream cheese and powdered sugar until smooth. Stir in vanilla extract.
04 - In a separate bowl, whip cold heavy cream to stiff peaks using an electric mixer.
05 - Gently fold whipped cream into the cream cheese mixture until fully combined and smooth.
06 - Spread the cream cheese filling evenly over the cooled crust using an offset spatula.
07 - Combine blueberries, sugar, cornstarch, lemon juice, water, and lemon zest in a saucepan. Cook over medium heat, stirring frequently, until mixture thickens and becomes glossy, about 6–8 minutes.
08 - Remove blueberry mixture from heat and let cool to room temperature. Carefully spread the blueberry topping over the cream cheese layer.
09 - Cover and refrigerate for at least 1 hour before serving to achieve the best texture and flavor.
