Chocolate Chip Cookie Pie

Preheat oven to 325 degrees F. In a large bowl, beat eggs until pale yellow and foamy, 2 to 3 minutes. Add flour, sugars, and softened butter and mix until combined and fluffy. Stir in chocolate chips and walnuts. Grease a pie dish with cooking spray. Add refrigerated pie crust and fold up edges. Add cookie mixture and pat down to cover crust. Bake until a knife inserted into the center comes out clean and crust is golden, 55 minutes to 1 hour.
