Creating Magnolia Bakery Blueberry Jamboree is straightforward. Follow these simple steps to ensure a perfect outcome:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).

2. Prepare the Blueberries: In a medium bowl, combine the fresh blueberries, sugar, lemon juice, vanilla extract, cornstarch, and salt. Mix gently until well combined.

3. Prepare the Crust: In a separate bowl, mix the flour, oats, baking powder, cinnamon, and softened butter. Use your fingertips to work the butter into the dry ingredients until crumbly.

4. Assemble the Dessert: In a greased baking dish, pour in the blueberry mixture evenly. Top it with the oat mixture, spreading it to cover the blueberries well.

5. Bake: Place the baking dish into the preheated oven. Bake for 45-50 minutes or until the topping is golden brown and the blueberries are bubbly.

6. Cool Down: Once baked, remove from the oven and let cool for 15-20 minutes. This cooling time will help set the filling.

7. Serve: Cut into squares and serve warm or at room temperature. You can add a scoop of vanilla ice cream on top for an extra touch.

By following these steps, you’ll have a delightful Magnolia Bakery Blueberry Jamboree ready to be enjoyed.
