Creating Blueberry Cream Cheese Bars is a fun process if you follow these simple steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C). Grease an 8×8-inch baking pan or line it with parchment paper for easy removal.
2. Combine Dry Ingredients: In a mixing bowl, combine the flour, rolled oats, granulated sugar, baking soda, and salt. Mix well until combined.
3. Add Butter: Pour the melted butter into the dry ingredients. Stir until everything is well moistened and crumbly.
4. Press Mixture: Take two-thirds of the oat mixture and press it evenly into the bottom of the prepared baking pan to form a crust.
5. Prepare the Cream Cheese Mixture: In another bowl, beat the softened cream cheese with the powdered sugar and vanilla extract until smooth and creamy.
6. Spread Cream Cheese Mixture: Spread the cream cheese mixture evenly over the oat crust in the pan.
7. Add Blueberries: Gently scatter the blueberries over the cream cheese layer, distributing them as evenly as possible.
8. Top with Remaining Oat Mixture: Crumble the remaining oat mixture over the blueberries, covering them completely.
9. Bake: Place the pan in the preheated oven and bake for 30-40 minutes or until the top is golden brown.
10. Cool and Slice: Once baked, remove from the oven and let the bars cool in the pan for about 15-20 minutes. After cooling, cut them into squares and serve.

With these straightforward steps, you will be able to bake an incredibly delicious batch of Blueberry Cream Cheese Bars!
