Mix 2 soften sticks of Imperial Margarine with 1 C. of dark (& I mean DARK) brown sugar and 3/4 c. of sugar. Add two eggs, one at a time. 3/4 tsp. of baking soda, 1/8 tsp of salt. Gradually add 3 C. of flour, then 1 tsp. of vanilla. Mix in 2 cups of chocolate chips. Bake at 350 for 10 minutes. The cookies will appear light in color but they are finished baking. The cookies will be similiar to a soft drop cookie.
