Canadian Living's best chocolate chip cookies

So I needed some cookies for our VBS. These turned out really well. They were also flat too. Sorry no picture for this one.

Ingredients

* 1/2 cup butter
* 1/2 cup shortening
* 1 cup granulated sugar
* 1/2 cup brown sugar, packed
* 2 large eggs
* 2 teaspoons vanilla
* 2 cups all-purpose flour (for a firmer cookies, add about 1/4 cup more flour)
* 1 teaspoon baking soda
* 1/2 teaspoon salt
* 2 cups chocolate chips (I used mini chips)
* 1 cup walnut, chopped (I'd add more chocolate chips if you do not include pecans) (optional)
or pecan

Directions

1.
In a large bowl, cream together butter and shortening; gradually mix in sugars, creaming thoroughly.
2.
Beat in eggs and vanilla.
3.
Combine flour, baking soda and salt; blend into creamed mixture. Stir in chocolate chips and nuts.
4.
Chill for a few minutes or let stand at cool room temperature for 30 minutes.
5.
Drop by rounded teaspoonfuls onto lightly greased baking sheets.
6.
Flatten slightly and smooth edges to make 1/2-inch thick cookie.
7.
Bake in a 375°F oven for 8-9 minutes or until golden brown around the edges and still slightly under-baked in the center. Let stand on baking sheet for 5 minutes; remove to racks to let cool completely.
