Follow these step-by-step instructions to ensure your No Bake Blueberry Cheesecake Bars turn out perfectly:

1. Prepare the Crust: In a mixing bowl, combine graham cracker crumbs, melted butter, and granulated sugar. Mix until well combined and crumbly.

2. Press the Crust: Press the graham cracker mixture into the bottom of a greased 9×9 inch baking dish to form an even layer. Set aside.

3. Make the Cheesecake Filling: In a large bowl, beat the softened cream cheese until smooth and creamy. Gradually add powdered sugar and vanilla extract, mixing well.

4. Whip the Cream: In a separate bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until fully combined.

5. Spread the Filling: Pour the cheesecake filling on top of the prepared crust. Smooth the top with a spatula and refrigerate for about 4 hours or until firm.

6. Prepare the Blueberry Topping: In a saucepan over medium heat, combine fresh blueberries, granulated sugar, lemon juice, and cornstarch (if using). Cook for 5-7 minutes until the blueberries start to burst and the mixture thickens slightly. Remove from heat and let cool.

7. Top the Bars: Once the cheesecake has set, remove it from the refrigerator. Spread the cooled blueberry topping evenly over the cheesecake layer.

8. Slice and Serve: Use a sharp knife to cut into bars. For best results, clean the knife between cuts.

By following these steps, you’ll create an unforgettable dessert that will leave everyone craving more.
