Sarah's Chocolate Chip Cookies

These are the best cookies ever. The key is to add just the right amount of flour and take them out of the oven at the right time.

1 cup sugar
1 cup firmly packed brown sugar
1 cup margarine or butter, softened
2 eggs
1 1/2 teaspoons vanilla
1 teaspoon baking soda
1 teaspoon salt
2 1/2 cups all-purpose flour
12 ounces semi-sweet chocolate chips

Place sugar, brown sugar and margarine in bowl and mix. Then add eggs and vanilla and mix.

Gradually add baking soda, salt and flour to the sugar mixture and beat until mixed well. Add chocolate chips and mix briefly.

Drop onto cookie sheets about 2 inches apart. Bake at 375 degrees for 10-12 minutes. Take out of oven when outside of cookie is just turning brown (the middle will look slightly undercooked) Let sit on cookie sheet for 2-3 minutes then cool on wire racks.
