Chocolate chip cookies (the best recipe to freeze)

I make a batch of this cookie dough, freeze it in cookie dough balls and whenever we want a warm chocolate chip cookie (perfect with ice cream!) we can just throw them in the oven.  These are thick, chewy, big and must be eaten warm :)

Ingredients:

1 cup unsalted butter, softened
1/2 cup shortening
1 1/2 cups dark brown sugar
1/2 cup sugar
2 eggs
4 teaspoons vanilla extract
4 1/3 cups flour
2 tablespoons cornstarch
2 teaspoons baking soda
1 1/2 teaspoon salt
1 bag mini chocolate chips or half and half mini and chunks

Directions:

1. Mix the butter, shortening and sugar until light and fluffy.
2. Add the eggs and vanilla and mix until combined.
3. In a separate bowl, combine the flour, cornstarch, baking soda, and salt then slowly add to creamed mixture.
4.* the dough should not be sticky...
5.  Add chocolate chips.
6.Form cookie dough into balls using a 1/4 inch scoop or measuring cup and freeze for at least 2 hours or up to 3 months.

7.  To bake: place frozen cookie dough balls on a parchment lined baking sheet and bake at 350 degrees for 15 minutes.
