Chocolate Chip Bars

Chocolate Chip Bars - from My Baking Adventures, originally from Cookie Madness
8 oz regular salted butter (2 sticks) - I used unsalted butter
1 1/4 cup granulated sugar
1 cup of brown sugar, packed
4 large eggs
1 tablespoon of pure vanilla extract
3 1/2 cups all purpose flour
1 1/2 teaspoon baking soda
1/4 teaspoon salt (optional) - I added the salt
2 (12 oz) packages of semi-sweet chocolate chips
2 cups chopped pecans (optional) - I omitted the pecans

Cream the butter and sugars, beat in the eggs and vanilla.. Combine the dry ingredients and blend in. Add chips and nuts. Spread in a greased 15x 10 inch baking pan. Bake at 350F for 15-20 minutes. Cool and cut into bars.
