ingredients
1      single crust of Perfect Pie Crust
1    cup   all-purpose flour
1/4   teaspoon   salt
1/4   teaspoon   baking soda
6    tablespoons   unsalted butter, softened
5    tablespoons   packed light brown sugar
5    tablespoons   granulated sugar
1      large egg
1/2   teaspoon   vanilla extract
1    cup   semisweet chocolate chips
directions
Heat oven to 350 degrees F and place rack in the lower third. Line a 9-inch pie plate with crust and trim edges. Place in freezer until ready to fill.
Combine flour, salt, and baking soda; set aside. In the bowl of a mixer cream butter, brown sugar, and granulated sugar until fluffy. Mix in the egg and vanilla. Add flour mixture and blend until just combined. Stir in chocolate chips. Smooth into crust-lined pan.
Bake until pie is golden and center is just set but not overcooked, about 45 min. Cover with foil during the last 10 min to prevent overbrowning. Let pie cool almost completely and slice.
