These cookies are perfectly soft and chewy, and the first cookie I have ever had that is fantastic right out of the oven but ever better the next day.
Adapted from Apple a Day
3 sticks unsalted butter, softened
1 1/2 c. brown sugar
1/2 c. granulated sugar
1 Tbsp vanilla extract
4 c. flour
4 tsp. cornstarch
2 tsp. baking soda
1 tsp. salt
1 (10 oz) bag peanut butter chips
1 (12 oz) bag chocolate chips
Beat the butter until smooth. Beat in the brown and granulated sugar and continue beating until light. Beat in the eggs and vanilla extract.
In a separate bowl combine the flour, cornstarch baking soda, and salt. Beat into the butter and mix until thoroughly incorporated.
Beat in both bags of chips.
Shape dough into 1 inch balls, flatten slightly, place on a baking tray and bake at 350 for 8 - 10 minutes. (They wont be browned on the top) Let sit on the pan for 5 minutes then transfer to a cooling rack. They are very soft when they first come out of the oven but they are cooked.
Makes 8 dozen cookies
Form the dough into balls, flatten slightly, and freeze until solid in a single layer on a baking sheet. When the dough balls are solid store in a plastic freezer bag. To use, let the dough thaw for 15 minutes then bake at 350 for 15 - 18 minutes
