Place soft margarine and both sugars in a bowl. Beat them until the mixture is very smooth. This should take about two minutes.

Add the eggs and vanilla to the bowl. Mix again on a medium speed. Ensure everything is well combined and creamy.

Stir in the flour, baking soda, and salt. Mix slowly so the flour does not fly out. Stop mixing once you see no white streaks.

Fold in the chocolate chips using a big spoon. Distribute them evenly throughout the thick dough. Do not overmix the batter here.

Drop rounded tablespoons of dough onto the sheets. Space them two inches apart for spreading. Bake for ten to twelve minutes until golden.
