Mom's Best Chocolate Chip Cookies

2 cups margarine - softened2 cups white sugar
1 cup brown sugar
4 eggs
4 tsp. vanilla
4 1/2 cups white flour
2 tsp. baking soda
2 tsp. salt
About 2 cups small chocolate chips (300 g package)

Soften margarine and beat in sugars, eggs, and vanilla till fluffy. Sift dry ingredients together, then add to egg mixture. Stir in chocolate chips. Spoon out onto ungreased cookie sheets. Bake at 350 degrees for 8-12 minutes.

Adjust the heat and timing so you have fully cooked cookies that are lightly brown on the bottom. Every oven is different!
