Creating these No-Bake Cheesecake Flag Bars is a simple and joyful process. Follow these steps:

1. Prepare the Pan: Line a 9×9-inch square baking dish with parchment paper, allowing some overhang for easy removal later.
2. Make the Crust: In a medium bowl, combine graham cracker crumbs and melted butter. Stir until fully combined and crumbly.
3. Press the Crust: Firmly press the crumb mixture into the bottom of the prepared baking dish to create an even layer.
4. Prepare the Cheesecake Filling: In a large mixing bowl, beat the softened cream cheese until smooth.
5. Add Sugar and Vanilla: Gradually add in powdered sugar and vanilla extract. Continue mixing until fully blended.
6. Whip the Cream: In a separate bowl, whip the heavy whipping cream until stiff peaks form.
7. Combine Mixtures: Gently fold the whipped cream into the cream cheese mixture until well combined, ensuring the fluffiness remains.
8. Layer the Filling: Spread the cheesecake mixture evenly over the crust in the baking dish.
9. Chill: Cover the dish with plastic wrap and place it in the refrigerator to chill for about 2 hours, or until set.
10. Add Toppings: Once set, remove the cheesecake from the refrigerator. Arrange the sliced strawberries and blueberries on top to resemble the American flag.
11. Slice: Use a sharp knife to cut into squares or bars, utilizing the parchment overhang to lift them out easily.
