Recipe(tried): Soft Chocolate Chip Cookies for Cathy/NY

Cathy, my family has made these for over 30 years!
Everyone asks for the recipe! They are delicious but the softness really comes from the baking time. Do not overcook. When they are baked, you won't be sure that they are quite done but they are. I always double the recipe as they are gone too fast! They freeze well and are still chewy. (If they aren't all gone!)

SOFT CHOCOLATE CHIP COOKIES

1/2 c. margarine
1/2 c. brown sugar
1/4 c. white sugar
1 egg
1 1/4 c. flour
1/2 tsp. salt
1/2 tsp. baking soda
1/2 tsp. vanilla
1 c. chocolate chips, not the tiny ones. (I add about another 1/4 c for each batch.)

Cream the sugars and margarine together. Add egg and mix well. Add the flour, salt and baking soda and mix well again. Mix in the vanilla. Add the chocolate chips and mix carefully.

Drop by the heaping teaspoonful on a greased baking sheet. Bake at 350 for 8-9 minutes. They will look just slightly underbaked but they aren't.

Note: I keep these cookies in an airtight cookie tin. Bake only one cookie sheet at a time and ALWAYS MIX by hand.
