Creating the Magnolia Bakery Blueberry Jamboree is a simple yet rewarding process. Follow these steps to bring this incredible dessert to life:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Make the Crust: In a mixing bowl, combine flour, sugar, and salt. Cut in cold butter until the mixture resembles coarse crumbs.
3. Add Water: Stir in ice water, one tablespoon at a time, until the dough comes together. Form the dough into a disk, wrap it in plastic, and refrigerate for at least 30 minutes.
4. Prepare the Filling: In another bowl, mix blueberries, sugar, lemon juice, lemon zest, cinnamon, and cornstarch. Gently toss to combine and set aside.
5. Roll Out Dough: On a floured surface, roll out the chilled dough to fit your pie pan. Place the rolled dough into the pan, trimming any excess.
6. Fill the Crust: Spoon the blueberry filling into the prepared crust, spreading it evenly.
7. Prepare Streusel Topping: In a small bowl, combine flour, sugar, and cinnamon. Cut in cold butter until the mixture is crumbly.
8. Add Streusel: Sprinkle the streusel topping evenly over the blueberry filling.
9. Bake: Bake in the preheated oven for 40-45 minutes or until the streusel is golden brown and the filling is bubbling.
10. Cool: Once done, remove from the oven and allow to cool for 15-20 minutes before serving.
