Double Blueberry Cookie Pie

1 (18 ounce) tube refrigerated sugar
    cookie dough, room temperature
1/3 cup all-purpose flour
3 cups fresh or frozen blueberries
3/4 cup granulated sugar
3 tablespoon cornstarch
Dash of salt
1 teaspoon lemon juice
1 cup heavy (whipping) cream, whipped

Preheat oven to 350 degrees F. Spray a 9-inch pie pan and small cookie sheet with nonstick cooking spray.

In a small bowl combine sugar cookie dough and flour until mixed. Remove about one-fourth of the cookie dough; cover with plastic and refrigerate for later use.

With floured hands, press unrefrigerated dough onto bottom and up sides of prepared pan. Place in freezer to firm up, about 15 minutes.

On a lightly floured surface with a floured rolling pin, roll out refrigerated cookie dough 1/4-inch thick. With a floured cookie cutter, cut out stars or other shapes; place on prepared cookie sheet. Bake cookie dough pie crust until golden, about 11 minutes and stars for about 6 minutes. Cool on wire racks.

Meanwhile, in a medium saucepan, combine 1 cup of the blueberries, the sugar, cornstarch and salt. Stir in 2/3 cup water and the lemon juice. Over medium-high heat, bring to a boil. Boil, stirring constantly, until mixture thickens, crushing blueberries. Stir in remaining 2 cups blueberries; chill.

Spoon blueberry mixture into cooled cookie shell. Decorate with the star-shaped cookies and whipped cream.
