Making Easy Blueberry Bars with Cheesecake Layers is simple if you follow these organized steps:

1. Preheat Your Oven: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper for easy removal.

2. Prepare the Base: In a large bowl, combine flour, oats, sugars, baking soda, and salt. Pour in the melted butter and mix until crumbly. Press the mixture evenly into the bottom of the prepared baking dish.

3. Bake the Base: Bake the mixture for about 10-12 minutes or until lightly golden. Remove from the oven and set aside to cool slightly.

4. Make the Cheesecake Layer: In a medium bowl, beat the softened cream cheese and granulated sugar together until smooth. Add the egg and vanilla extract, mixing until combined.

5. Spread the Cheesecake: Pour the cheesecake mixture over the baked base, spreading it evenly.

6. Prepare the Blueberries: In a separate bowl, gently toss the blueberries with sugar, cornstarch, and lemon juice until well-coated.

7. Add Blueberries: Evenly distribute the blueberry mixture over the cheesecake layer.

8. Bake Again: Return the dish to the oven and bake for an additional 25-30 minutes, or until the cheesecake is set and the blueberries have burst slightly.

9. Cool Down: Remove the baking dish from the oven and let it cool at room temperature for about 15-20 minutes. Then, transfer it to the refrigerator to chill for at least 2 hours before cutting.

10. Slice and Serve: Once chilled, slice into bars and serve. Enjoy them chilled or at room temperature for the best experience!
